COMPOSITE PIPE MATERIAL FOR INSULATING JOYSTICK AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2019/047401

A1

Provided in the embodiments of the present invention are a composite pipe material for insulating a joystick and a preparation method therefor, the pipe material being made of a resin and fibre fabric composite, the resin comprising epoxy resin and the fibre fabric being cross-overlapped and wound into a roll. The embodiments of the present invention solve the problem of impregnation of traditional resin and fibre fabric by means of the winding composition of the fibre fabric and the design of the winding method, ensuring the effective infiltration of the epoxy resin system into the fibre fabric, effectively increasing the dipping amount of the composite material, improving the problem of the impregnation of the resin into the fibre fabric, and being able to ensure that the composite material tube has excellent mechanical properties and electrical insulation properties whilst effectively reducing the weight of the composite material tube.
