Problems solved by technology

However, in the above method, the wound material is not extruded, resulting in low dimensional accuracy of the thin-walled carbon fiber composite skirt.
[0005] In addition, the existing mandrel and the mandrel are of an integrated structure, and the mandrel is generally a wearing part. When the mandrel is damaged, the mandrel and the mandrel need to be replaced together, which increases the maintenance cost

Abstract

The invention relates to a winding and curing device for thin-walled skirts made of carbon fiber composite materials, which includes a mandrel, a core mold installed on the mandrel, an inner wedge-shaped cylinder, an outer wedge-shaped cylinder, an upper pressure plate, a base, a screw, The upper regulating plate and the lower regulating plate, after using the winding curing device of the carbon fiber composite material thin-walled skirt type part of the present invention, can squeeze and solidify the fibers wound in the mandrel as a whole, and then heat and demould, in this way An extrusion curing process is added between winding and heating, which can further improve the dimensional accuracy, shape tolerance and surface finish of the carbon fiber composite thin-walled skirt.

Description

technical field [0001] The invention relates to the molding of the skirt body of the accessory part of the solid rocket motor casing, in particular to a winding and curing device for the thin-walled skirt part of carbon fiber composite material. Background technique [0002] The solid rocket motor is the power device of the aerospace vehicle, which is composed of a charge combustion chamber, a nozzle and an ignition device. As an important power device for space delivery and missile propulsion systems, with the rapid development of aerospace technology, the development trend of solid rocket motors is high speed, high precision, small mass, high specific impulse, and high thrust-to-mass ratio. The structural quality of the solid rocket motor shell is the most important part of the negative mass of the engine, which has a great impact on the performance of the engine. Therefore, high-strength and light-weight shell materials should be selected. Carbon fiber composite material...
