Problems solved by technology

The melt viscosity is large, and the viscosity changes little with temperature, which brings great difficulties to the molding process of thermoplastic resin-based composite materials. Conventional methods for manufacturing thermosetting resin prepregs are generally not applicable to the preparation of thermoplastic resin prepregs material

Abstract

The invention belongs to the technical field of materials and relates to a glass fiber reinforced PEEK (polyether-ether-ketone) unidirectional tape. PEEK resin is taken as a matrix, glass fiber is taken as a reinforcing material, a suspension glue solution impregnation technology is adopted, combing, suspension system stabilization keeping and gluing quantity control are realized by the aid of hydraulic pressure, and the glass fiber reinforced PEEK unidirectional tape is obtained through glue concentration control, preheating and high-temperature compression. The glass fiber reinforced PEEK unidirectional tape comprises the PEEK resin and the glass fiber, the fiber volume fraction is 50%-62%, the glue solution adopts an aqueous suspension system, the turbidity is 3.2-6.7 g / L, and the glass fiber reinforced PEEK unidirectional tape at least comprises components in parts by mass as follows: 10 parts of the PEEK resin and 10-30 parts of a composite wetting dispersant. The glass fiber reinforced PEEK unidirectional tape contains uniform glue, has stable glue content as well as excellent viscosity and drapability and is applicable to winding molding and hot-press molding, and a product can be applied to the industries such as spaceflight, aviation, automobiles, chemical engineering and the like.

Description

technical field [0001] The invention belongs to the technical field of materials. It involves the design technology of fiber-reinforced composite materials, especially the design and processing technology of fiber-reinforced high-temperature resistant thermoplastic resin-based composite material prepreg. Background technique [0002] Unidirectional tape is a kind of prepreg, which is impregnated with continuous fiber under strictly controlled conditions with resin matrix to make a composition of resin matrix and reinforcement. It is an intermediate material for the preparation of composite materials and the basis of composite materials. With the emergence of high-performance reinforcing fibers such as carbon fiber and aramid fiber in the early 1970s and new high-performance thermoplastic resins in recent years, some properties of composite materials have been greatly improved, prepregs have attracted people's attention, and technology has gradually development, the scope of...
