Method for coating composite structures with a multi-axial crystalline thermoplastic coat

摘要

A method for thermoplastic coating composite structures includes applying a crystalline multi-axially oriented thermoplastic layer (14) onto a working surface (12) of a tool (10). A layer of composite material (16) is applied onto the crystalline multi-axially oriented thermoplastic layer (14), and the crystalline multi-axially oriented thermoplastic layer (14) and the layer of composite material (16) are cocured at a specific temperature and pressure in an autoclave. The softening temperature of the crystalline multi-axially oriented thermoplastic layer (!4) is not substantially greater than the curing temperature of the composite material (16). To be accompanied, when published, by Figure 1C of the drawings.
