Dipping technique for longitude and latitude overlapped non-weaving compound material

Abstract

The invention relates to the dipping technical field, in particular to a dipping technique for a longitude and latitude overlapped non-weaving compound material which comprises the steps of presoaking, dipping and suppressing. The invention adopts a constant-temperature wet process to dip, guides the uniformly unfolded fibers to pass through a dipping tank at a constant speed under a constant-temperature condition, can solve the problem that fiber cannot be steeped thoroughly in thermoplastic resin and can ensure that the fiber is fully steeped in a dipping tank so as to greatly promote the physical properties and the mechanical properties such as product tensile strength, flexural strength, and the like.

Description

technical field [0001] The invention relates to the technical field of dipping technology, in particular to a dipping technology of warp and weft overlapping non-woven composite materials. 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 glass fiber conte...
