Abstract
A multi-arm forming device for space on-orbit composite braiding is provided. Through the rotary movement of a combination of circularly arranged mechanical arm-type laying apparatuses relative to a mold, a plurality of hot press laying heads are controlled together to implement high-efficiency and high-freedom winding and braiding formation of a composite member. The retraction and expansion deformation of the gasbag mold is achieved by inflating and deflating based on design, and the overall device is lightened by switching its structural volume in an operating/non-operating state, thereby achieving the purpose of facilitating the lift-off of rockets and the demolding, repair and weight reduction of winding and braiding structural members for operation in space. Additionally, gas in a gasbag can be used as emergency kinetic energy for the movement and attitude adjustment of the overall device in space. High-quality and efficient winding and braiding formation of composites in space are achieved ultimately.
