Abstract

The invention provides a device and a method for preparing a composite material rib by using a thermoplastic fiber reinforced resin-based prepreg tape, and belongs to the technical field of preparation of composite material ribs. The problems of high porosity and low impregnation degree during preparation of the fiber-reinforced thermoplastic composite material rib at present are solved. The device comprises a top cover and a bottom groove, the top cover is divided into a top cover guide area and a top cover shaping area, the top cover shaping area is a convex platform arranged at the right end of the lower surface of the top cover, the bottom groove is divided into a bottom groove guide area and a bottom groove shaping area, and the bottom groove shaping area is a concave platform arranged at the right end of the upper surface of the bottom groove. The top cover guiding area and the bottom groove guiding area are respectively provided with a plurality of long-strip-shaped groove bases, a guiding roller is arranged in each long-strip-shaped groove base, the guiding rollers and the long-strip-shaped groove bases are fixedly connected with the corresponding top cover or the corresponding bottom groove through a plurality of fixing bolts, and the guiding rollers on the top cover and the guiding rollers on the bottom groove are arranged in a one-to-one staggered mode. The prepared product is low in porosity and good in dimensional stability.

Description

technical field [0001] The invention belongs to the technical field of preparation of fiber-reinforced thermoplastic composite material bars in civil engineering, and in particular relates to a device and method for preparing composite material bars by using thermoplastic fiber-reinforced resin-based prepreg tapes. Background technique [0002] The structural materials used in marine engineering are mainly steel, but under complex service environment, steel is susceptible to chemical corrosion, microbial corrosion and physical corrosion, which seriously reduces its bearing capacity, damages the structure, and reduces service life. Fiber reinforced polymer (FRP) has the characteristics of light weight, high strength and corrosion resistance. Its application in marine engineering to replace steel bars is expected to achieve high performance and long life of marine engineering structures. [0003] At present, FRP rods on the market are mainly thermosetting, and the resin matrix...
