Processing equipment of longitude and latitude overlapping non-weaving composite material

Abstract

The invention relates to a longitude and latitude overlapping non-weaving composite material, in particular to processing equipment of the longitude and latitude overlapping non-weaving composite material. The processing equipment comprises a creel, a dragging silk distribution device, a tension regulator, a wire feeder, a glue spraying device, an immersion device, a drier, an anti-static device and a winder which are successively connected in order. The product produced by the bidirectional equipment at 0-90 degrees adopted by the invention can solve the problem that fiber can not be completely immersed in thermoplastic resin to ensure that fiber is fully immersed in an immersion groove; thus mechanical properties and certain physical properties, such as tensile strength, flexural strength and the like of the product can be greatly improved; particularly, the bidirectional product at 0-90 degrees has same mechanical property and physical property in lateral direction and longitudinal direction so as to meet the high property requirement of various products.

Description

technical field [0001] The invention relates to a warp and weft overlapping non-woven composite material, in particular to a processing equipment for warp and weft overlapping non-woven composite material. Background technique [0002] The development of modern high technology is inseparable from composite materials. Composite materials play a very important role in the development of modern science and technology. Among them, continuous fiber-reinforced thermoplastic resin composite materials have excellent mechanical properties such as high tensile strength, bending strength / mold Weight, high and low temperature impact strength, etc., and has the characteristics of relatively low density and recyclability, so it has been greatly developed in recent years. [0003] The patent with the publication number CN101474868A discloses a continuous reinforced thermoplastic resin composite material and its preparation equipment. However, the material has certain limitations: 1. The ...

Problems solved by technology

[0003] The patent with the publication number CN101474868A discloses a continuous reinforced thermoplastic resin composite material and its preparation equipment. However, the material has certain limitations: 1. The glass fiber content of the unidirectional sheet produced according to the CN101474868A patent process is very low. 55%, while the glass fiber content of products produced by 0-90° two-way equipment can reach 75%, or even exceed; 2. The problem of incomplete impregnation of fibers in thermoplastic resins will directly affect the quality of products and finished products. Physical properties and mechanical properties, the key part of the patent of CN101474868A is that the fiber is passed through the twin die heads of thermoplastic resin in the extruding molten state, and the fiber is impregnated in the "S" type process, which can only be achieved by the tension of the fiber and the mouth of the die. The pressure of spraying molten resin or impregnating against the die mouth, its products cannot ensure that every bundle of fibers is impregnated
