Abstract

The invention relates to a monopolymer composite product supercooled membrane and superheated wire forming method and device, and belongs to the technical field of polymer composite material forming and processing. According to the method, membranes and continuous fibers of polymers of the same kind are prepared, the continuous fibers are in an overheated state through constraint traction, the molten membranes are rapidly cooled to an overcooled state, then fiber yarns are placed in the middles of the membranes, the fibers and the membranes are compounded through mold closing, and finally cooling and curing are carried out to obtain a monopolymer composite product. The device is composed of a mold, a fiber winding frame, a mold closing system and a temperature control system. The method and the device are used for preparing the monopolymer composite product small in density, high in recycling rate and good in interface cohesiveness, a processing temperature window wider than that of a traditional preparation method can be established, and the product with the mechanical strength close to the theoretical mechanical strength can be obtained.

Description

technical field [0001] The invention relates to a method and a device for forming a supercooled film superheated filament of a single polymer composite material product, and belongs to the technical field of polymer composite material forming and processing. Background technique [0002] In recent years, fiber-reinforced polymer composites have been widely used and developed rapidly, especially meeting the urgent needs of automotive lightweight development. With people's continuous attention to energy conservation and environmental protection, improving the recycling performance of fiber reinforced polymer composites has become a research hotspot in related industries. Traditional fiber-reinforced polymer composites are composed of a matrix and a reinforcement, usually with a polymer as the matrix, and glass fibers, carbon fibers, boron fibers, aramid fibers, silicon carbide fibers, etc. as reinforcements. The polymer matrix mainly includes two types of thermosetting polyme...
