Embodiment

[0064] In this embodiment, the equipment for rapidly setting the molding process parameters of the resin-based composite material is used to formulate the molding process parameters of the high-temperature-resistant polyimide resin-based composite material, and the specific steps are as follows:

[0065] The first step: determine the resin matrix composite material process parameters to be screened for the polyimide resin matrix composite material: target temperature, heating and cooling rate, holding temperature, curing temperature, pressurization temperature, pressure, vacuum degree, a total of 7;

[0066] The second step: according to the determined seven process parameters of the polyimide resin matrix composite material, install the corresponding seven groups of test unit devices in the integrated combined box;

[0067] The third step: put the pre-cured polyimide resin-based composite material used in the test into the vacuum tank 3;

[0068] The fourth step: start the te...

Abstract

The invention discloses a device and method for rapidly formulating molding process parameters of resin-based composite materials. The device includes an integrated box body, a display console, a modular test unit device, and an integrated control system, wherein: the display The console and the integrated control system are embedded on one side of the integrated combined box; the modularized test unit device is located inside the integrated combined box. The present invention can obtain the optimal molding process parameters by iteratively screening different parameter variables through one test, abandons the traditional method of controlling a single invariant to screen and determine the remaining invariants, greatly reduces the number of tests and cycles, saves costs, and improves the production efficiency. Parameter optimization efficiency, and at the same time, for the first time, real-time data collection under the joint influence of different parameters is realized, which makes up for the shortcomings of large deviations in traditional screening process parameters.

Description
