Abstract

The invention discloses a flat plate type thermoplastic PEKK carbon fiber one-way belt laminated plate and a processing method thereof. Comprising the following contents: (1) the laying mode of the flat plate type thermoplastic PEKK carbon fiber one-way belt laminated plate, (2) the processing technological parameters of the flat plate type thermoplastic PEKK carbon fiber one-way belt laminated plate, (3) the processing method of the flat plate type thermoplastic PEKK carbon fiber one-way belt laminated plate, (4) the mold surface structure design of the flat plate type thermoplastic PEKK carbon fiber one-way belt laminated plate, and (5) the mold surface structure design of the flat plate type thermoplastic PEKK carbon fiber one-way belt laminated plate. The paving mode of the flat plate type thermoplastic PEKK carbon fiber one-way belt laminated plate in the step 1 is as follows: the thickness of a thermoplastic PEKK carbon fiber one-way belt is 0.1-0.2 mm. And the laying direction of the 20 layers of materials is [45 / -45 / 0 / 0 / 90 / 0 / 0 / 45 / -45 / 0] S. All layers of thermoplastic PEKK carbon fiber one-way belts are prevented from sliding during compression molding in a spot welding mode or a mode that the peripheries of the thermoplastic PEKK carbon fiber one-way belts are fixed through high-temperature adhesive tapes, the effect on the angle between fibers is avoided, and it is guaranteed that a hole sealing agent and a release agent can be better and effectively attached to the surface of a mold through control over the construction temperature of the hole sealing agent and the release agent; and the effects of hole sealing and demolding are achieved.

Description

technical field [0001] The invention relates to the technical field of processing a flat thermoplastic PEKK carbon fiber unidirectional tape laminate, in particular to a processing method for a flat thermoplastic PEKK carbon fiber unidirectional tape laminate. Background technique [0002] There are mainly the following types of composite materials for aerospace: metal matrix composites, ceramic matrix composites, carbon / carbon composites and resin-based composites. Among them, resin-based composites are the most widely used in the aviation field. The weight of manufacturing aircraft parts is 20-30% lower than that of metal materials, and the maintenance cost is reduced by 15-20%. Therefore, the amount of resin-based composite materials has become one of the indicators to measure the advanced structure of aircraft. [0003] In the prior art, the processing method of a flat thermoplastic PEKK carbon fiber unidirectional tape laminate has disadvantages: [0004] 1. Patent do...
