Example Embodiment

[0018] Example 1

[0019] A preparation method of a thermoplastic fiber hybrid woven composite material includes three steps: the production of thermoplastic wrapping yarn, the weaving of the composite material preform and the woven composite material molding process, wherein the thermoplastic wrapping yarn is made of reinforcing fibers It is composed of thermoplastic resin fiber, and the existing fiber wrapping technology is used to mix the reinforcing fiber with the thermoplastic resin fiber in a feasible volume ratio. The volume fraction of thermoplastic fiber is 40%, and the volume fraction of reinforcing fiber is 60%. The thermoplastic resin fiber is evenly coated on the reinforcing fiber to form a thermoplastic wrapping yarn. Using a fancy twisting machine, three filament fibers of industrial polyester (PET), glass fiber (GF) and polypropylene (PP) are combined without twist at a volume ratio of 3:3:4, and then thermoplastic resin fiber is used PP filaments are coated to p...

Abstract

The invention discloses a method for preparing a thermoplastic fiber-hybrid woven composite and is characterized by comprising the following three steps: preparing thermoplastic fasciated yarns, weaving a pre-manufactured composite and molding the woven composite, wherein the thermoplastic wrapping yarns consist of strengthened fibers and thermoplastic resin fibers which are mixed according to the volume by adopting a fiber wrapping technology, the thermoplastic fibers are 40 to 80 volume percent and the strengthened fibers are 20 to 60 volume percent; and then the thermoplastic resin fibers are uniformly covered on the strengthened fibers to form the thermoplastic wrapping yarns. The thermoplastic composite is a big trend in the further composite development and has a bright development prospect.

Description

technical field [0001] The invention relates to a preparation method of a thermoplastic fiber hybrid woven composite material, which belongs to a low-cost processing method that can be recycled and reused. Background technique [0002] In recent years, with the development of automobiles, electrical appliances, construction, aviation, etc., thermoplastic resin-based composite materials have attracted more and more attention at home and abroad, and have become an extremely active research and development point in the field of composite materials. Compared with thermosetting composite materials, thermoplastic composite materials have many advantages: (1) thermoplastic resin composite materials have high toughness and high damage tolerance, and good impact resistance. (2) The fatigue resistance of thermoplastic composite materials greatly exceeds that of thermosetting resins, so the service life is relatively high. (3) The thermoplastic composite material has strong chemical a...
