A device for the continuous control of the distribution of the binder on the structure of the wound product and study of new technical features compared to the prototype is based on the following theoretical assumptions: physico-mechanical properties of the products obtained by winding of composite materials in determining the extent determined by such process operations as impregnation, winding and heat treatment (curing). When organizing an information display process bottleneck is getting the information about the peculiarities of the process of mass transfer in the wound product. However, it is known that the processes occurring at the boundary of the filler - binder, largely determine the physico-chemical properties of the product. The parameters of these processes depend on the specifics of diffusion phenomena in the surface layer. These two the situation, basically, describes the laws of penetration (diffusion law Darcy, laws of transfer Fika). So, according to the first law Fika density of the particle stream grade A (flux binder) - JmAin the direction of the axis x from greater concentration to lesser described by the expression

JmA=DAdcA/dx,

where DAis the diffusion coefficient of the particles grade A;

cAthe concentration of particles varieties of A.

The second law Fika describes the dependence of the derived concentration by the time dcA/dt diffusing particles:

dcA/dt=DAd2(cA)/dx2.

The laws indicate that the properties of mass transfer in the boundary layer flux binder JmAthe rate of change of the concentration of the binder dcA/dt, the average concentration of cAdepend on the magnitude of the second derivative of the concentration of the binder in the tape thickness wound of the product G(r). Assuming the value of Δr is equal to the thickness of the layer (tape) h0, the value of G(r) can be expressed through the number of wound layers:

where n is the layer number;

,,accordingly, the average content of the binder in the tape layers with n, n-1, n-2.

Thus, the measurement function G(n) in the winding process allows AEC to obtain information about the characteristics of the distribution of concentration of the binder thickness wound of the product.

Important information about the phenomena in the surface layer can be obtained if to determine the value of Sras the ratio of the time derivative on the content of the binder in the tape to the flux density:

Given that the diffusion current density JmAdefined as the number of particles that passed in unit time through a unit surface, is expressed as the product of the velocity v on the concentration of diffusing particles cAafter transformation taking into account the above notation we obtain:

where

k=l0/πr0, l0- the length of the mandrel;

r0is the radius of the mandrel;

Hn- the content of the binder in the tape during winding of the n-th layer.

Denoting Pn/Hnthrough δHnthe expression (2) let us write in the form

where

The value ofandnproportional to the magnitude of the average velocity of the particles of the binder in the surface layer.

Therefore, for accurate display of the migration process, the binder, the volume of the winding process of the product it is necessary to organize continuous monitoring of parameters: H(n), G(n), P(n), an.

In order to improve the accuracy of control of the distribution of the binder by volume, the surface is divided into k is Chertkov (zones) and measured the content of the binder in the tape during the winding of the belt and then it is averaged. Each zone is controlled by the value of the parameters H(in)G(in)P(in),ainwhere i is the number of zones, n is the layer number.

The operation of the device is as follows: an information signal proportional to the content of the binder in the tape is fed from the output device for the continuous control of a percentage composition of carbon tape 3 that is installed near the surface of the mandrel winding machine 2, to the third input of the block timebase winding products 4. To monitor the distribution of the binder on the structure of the product is spatio-temporal decomposition of the winding process. To this end, the output of the shaper time intervals winding layer 10, the input of which receives signals from the limit switches 1, a pulse signal whose duration is proportional to the time of the winding layer of the product. The positive edge of the pulse starts a block of time marking the surface of the product 12, which represents, for example, a multivibrator, the duration of the positive pulse of the output voltage which is proportional to the time of winding the belt. The number of zones k is determined during the design process. The logical product of the positive values of the output voltage of the shaper time intervals winding layer 10 and the temporary block size is key the surface of the product 12, generated by the scheme And 14 by connecting its inputs respectively to the outputs of the shaper time intervals winding layer 10 and block temporary marking the surface of the product 12, is used to shift the contents of the cells of the register 16. This logical 1 is written in the first cell of the register 16, sequentially shifted by the cells of the register 16 and through the first group of valves 17, to the first inputs of which are connected to the third input of the block timebase winding of product 4, and control inputs connected to the outputs of the cells of the register 16, and connects the output device for the continuous control of a percentage composition of carbon tape 3 to the contact group output GR when winding the first and odd layers. Time intervals proportional to the second winding and the even-numbered layers of the product formed by the logical product of voltage and the inverse of the output of the shaper time intervals winding layer 10 and the output voltage of the temporary marking surface 12 formed by the output of the circuit And not 15 by connecting its inputs respectively to the respective outputs of the shaper time intervals winding layer 10 and block temporary marking the surface of the product 12. The output voltage of the circuit And not 15 is used as clock pulses for the reverse shift cell content of the register 16. The "reverse" resort is e 1, recorded in the k-th cell is shifted sequentially to the first cell of the register 16. The operation of the block timebase winding product 4 is illustrated in Fig.6. The time base percentage content of binder in the wound product on its surface is formed by the sequence of values of a group of signal present on the pin GR.

In order to control the distribution of the binder by volume of the product signals from connector GR first group of gates 17 of the block timebase winding products 4, are separated in the control unit of volume distribution of the binder 5 in accordance with the number of zones and the number of layer. For this group the signal connector GR control unit of volume distribution of the binder 5 is distributed to the first group the inputs of the blocks forming the layer distribution spanning 18 a number equal to the number of zones the surface of the product that allows you to "cut out" of the group of signal layer components of this zone. This operation is implemented through the distribution chain, containing the first memory register 22, in the first cell of which the winding of the first layer 1 is written. For this purpose in its zero cell recorded 1, which upon receipt of the first pulse shifts it to the first cell. When this state outputs its cells used throughout the world is how the control signals for the formation of the States of the second group of gates 21. Direct inputs of the second group of gates 21 receives signals proportional to the values of the binder in the same zone, therefore, changing the position 1 in the cells in accordance with the temporal properties of the output signal of the shaper time intervals winding layer 10, coming from the first output of the block timebase winding articles 4 and is proportional to the time of the winding of one layer, which is used as clock positive fronts of the pulse voltage at the first output of the block timebase winding products 4 for odd cells of the first memory register 22 and negative fronts for its even-numbered cells, perform switching group signal number layer winding. For averaging the percentage of binder in the surface layer, the outputs of the second group of gates 21 are connected to the contacts of the group of output blocks forming the layer distribution of the binder 18 through the drive 23. Therefore, the connector contacts PH control unit of volume distribution of the binder 5 are signals that show the distribution of the binder as the belt surface, and the layers within the zone. To obtain values of indicators of the nature of the transfer process of the binder between the layers of the product signals from the connectors PH control unit about the roadways distribution of the binder 5 is coming to the same connectors on the control unit the migration of the binder in the structure of the wound product 6, containing k blocks of the same type control layer indicators winding 19, the first group inputs connected to corresponding connectors PH control unit the migration of the binder in the structure of the wound product 6. To generate a voltage proportional to the value ofdetermined by (1) for the selected zone group inputs corresponding to the same type of control block layer indicators winding 19 connected with the first inputs of gates of the third group of valves 24, control their inputs connected to the outputs of the cells of the second memory register 25. The outputs of the third group of valves 24 alternately with the second memory register 25 are connected to the inputs of the three valves of the fourth group of valves 26, the control inputs of which are connected to the outputs of the cells of the first ring of the distributor 27, synchronized shifts from the second memory register 25. The outputs of gates of the fourth group of valves 26 are connected, respectively, directly to the first input through a factor of 2 to the second entrance and directly to the third input of adder 30. At the output of the adder is formed by the value of. Using the third memory register 33, synchronized through the entrance T 2 control unit layer indicators winding 19 of the voltage output from the frequency divider 13 block the timebase winding products 4, gates of the sixth group of valves 32 and drives the sixth group of valves 36 signals G(n) are distributed according to the connector PG(n) control unit layer indicators winding 19. In the same way with the second annular valve 29, the fifth group of valves 28 and subtractive device 31 at the output of the latter signals are formed(formula (3)), which using the third memory register 33, the seventh group of valves 34 and drives the seventh group of valves 35 are distributed to the contacts of the connector RP(n) control unit layer indicators winding 19. Connectors PG and PN control units layer indicators winding 19 is connected to the corresponding connectors of the control unit the migration of the binder in the structure of the wound product 6.

Information about the migration of the binder into the interlayer space is formed in the control unit of the kinetic properties of the binder in the surface layer 7. For this purpose, the connectors RP, PG control unit the migration of the binder in the structure of the wound articles 6 and connectors PH control unit of volume distribution of the binder 5 are connected with the same connectors on the control unit of the kinetic properties of the binder in the surface layer 7 consisting of k identical poyasovyj modules control the migration of the binder 20, group inputs RN, RP, PG signals with the respective connector blocks forming the layer distribution of the binder 18, connectors PN and PG blocks control flow indicators winding 19. The signals from the contacts of the connector RP potato managed through the gates of the eighth group of the valves 37 are served during a cycle determined by the number of the layer to the second input of the first divider 40 is connected also to the first input of the second divider 41, the first input of the first divider 40 is connected to the outputs of the ninth group of valves 38, the inputs of which are connected to the contacts of the connector PG oesophago module parameters control the migration of the binder 20, and the control inputs of the eighth group of the valves 37, ninth group of valves 38, the tenth group of valves 39 and eleventh groups of valves 43 is connected to the input S oesophago module parameters control transfer binder 20. The second input of the second divider 41 through the inputs of the tenth group of valves 39 is connected with the connector pins PH oesophago module parameters control the migration of the binder 20. Therefore, the output of the second divider 41 is formed by a voltage proportional to the value of δHn(formula 4), and the voltage at the output of the first divider 40 is proportional to the value of Sn(formula 2). The output voltage of the second divider 41 is supplied to the first input of the third divider 42, to the second input of which receives the output voltage of the first divider 40, the output of the third divider 42 is formed voltage, proportion is lnoe the value of a n(formula 4). The output of the third divider 42 through the gates of the eleventh group of valves 43 and drives the eleventh group of valves 44 are connected to the contacts of the connector PA oesophago module parameters control the migration of the binder 20, the contacts of which signals are formed, reflecting the kinetic properties of the binder, influencing processes of curing of the binder and its adhesion with the filler.
