A prepreg automatic laying process parameter determination device

Abstract

The invention relates to a prepreg automatic laying process parameter determination device, which belongs to the technical field of composite material automatic forming equipment design and is used for the simulation verification of the automatic laying process parameters of prepregs. The test device includes: a speed control unit, a pressure control unit, a temperature control unit, a control device and a data processing module. The prepreg data processing module (1) provides preset pressure to the prepreg through the flexible pressure roller (10) according to the set servo mechanism (8), sets the working parameters of the stepping motor (5), and sets the heating The constant temperature provided by the device (12) to the worktable (11) and the bonding force and strain force of the prepreg after the set laying process test are due to the optimal bonding force of the specific prepreg for laying and strain force are measurable data, and the best laying process parameters are determined according to the best bonding force and strain force of prepreg by adopting the reverse verification test method.

Problems solved by technology

[0003] The gliding warhead has a large size, complex shape, and many changes in curvature. The automatic lay-up and molding technology of the heat-resistant layer is difficult. During the lay-up process, the prepreg has undergone a complicated process. Only under the reasonable control of process parameters can a suitable adhesive bonding be achieved on the surface of the mold or the surface of the laid prepreg to ensure the molding quality of the heat-resistant layer. However, the determination of reasonable laying process parameters requires a large number of processes. Experiment and performance testing work, the development cost is high, the efficiency is low, and when the prepreg specification changes, the test verification of the laying process parameters needs to be carried out again
