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 solidification device for a carbon fiber composite thin-wall skirt part. The winding solidification device comprises a core shaft, a core mold main body installed on the core shaft, an inner wedge-shaped barrel, an outer wedge-shaped barrel, an upper pressing plate, a base, a screw, an upper adjusting plate and a lower adjusting plate. After the winding solidification device for the carbon fiber composite thin-wall skirt part is used, fibers wound on the core mold main body can be extruded and solidified, then heating and demolding are carried out, an extrusion solidification working procedure is additionally arranged between the winding working procedure and the heating working procedure, and the size accuracy, the form and location tolerance and the surface smoothness of the carbon fiber composite thin-wall skirt part can be further improved.

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...
