Heterogeneous laminated composite materials and products thereof

Abstract

The invention discloses a different material laminated composite sequentially comprising a first layer of structure, a center substrate and a second layer of structure; the first layer of structure isat least one of a first woven fiber layer, a metal layer and a first plastic layer; the center substrate is a thermoplastic plastic plate; the second layer of structure comprises a second woven fiberlayer and a second plastic layer or comprises a second woven fiber layer and a nonwoven fabric layer; the woven fiber layers of the first layer of structure and the second layer of structure are connected with the center substrate by a rubber layer; the difference of mechanical strengths of the first layer of structure and the second layer of structure is smaller than 20%; the center substrate isa main structural filling and supporting layer and can be made of varied materials, the structural strength, rigidity and shock resistance can be regulated due to the adoption of different materials;and the woven plastic plate which is a relatively woven layer is low in processing cost and simple in thermoplastic process and has market competitiveness.

Description

technical field [0001] The invention relates to a composite material, in particular to a composite material in which different materials are laminated. Background technique [0002] At present, the main development trend of the suitcase manufacturing industry is hard-shell suitcases. Hard-shell suitcases can be mainly divided into two types: plastic or metal, because plastic or metal can be processed into special shapes or shapes, and plastic or metal Compared with soft materials such as cloth, suitcases have high strength, durability and water resistance, and are very popular among consumers. [0003] Hard-shell suitcases made of plastic can be roughly divided into traditional plastic boards or composite plastic boards, etc., which are laminated in the form of single-layer or multi-layer boards and then pressed into shape. Although plastic boards or composite plastic boards are cheap, However, the structural strength is not good, and it is often unable to withstand strong ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve various problems in the current production of plastic or metal hard-shell luggage, if the structural strength is increased but the cost is increased, or the cost is reduced but the structural strength is sacrificed and the material selection is limited, the present invention provides a different Material laminated composite material, which sequentially includes a first layer structure, a central substrate and a second layer structure, wherein: the first layer structure is at least one of a first braided fiber layer, a metal layer and a first plastic layer One; the central substrate is a thermoplastic plastic plate; the second layer structure includes a second woven fiber layer and a second plastic layer, or includes a second woven fiber layer and a non-woven fabric layer; the first layer The first woven fiber layer and the second woven fiber layer in the structure and the second layer structure are respectively connected to the central substrate through an adhesive layer; and the mechanical strength difference between the first layer structure and the second layer structure value less than 20%
