CN101880943A - Warp and weft overlapping non-woven composite material - Google Patents

Abstract

The invention relates to the technical field of composite materials, in particular to a warp and weft overlapping non-woven composite material which is formed by mutually overlapping, dipping and pressing a warp layer and a weft layer, wherein the warp layer is bonded by a warp, the weft layer is bonded by a weft, and the included angle between the warp and the weft is 0-90 degrees. The composite material with 0-90 degrees prepared by two-way equipment can solve the problem of impermeable dipping of fiber in a thermoplastic resin to some extent, and ensure the fiber is fully dipped in a dipping tank, thus greatly improving physical properties and mechanical properties of the product such as tensile strength, bending strength and the like; and particularly the two-way product with 0-90 degrees has the same physical property and mechanical property in horizontal and longitudinal directions, thus meeting the high-performance requirements.

Description

Longitude and latitude overlapped non-weaving compound material

Technical field

The present invention relates to technical field of composite materials, especially a kind of longitude and latitude overlapped non-weaving compound material.

Background technology

The development of modern high technology be unable to do without composite, composite is to development of modern science and technology, crucial effect is arranged, wherein continuity fiber-reinforced thermoplastic resin composite has excellent mechanical performance such as high-tensile strength, bending strength/modulus, high/low-temperature impact intensity etc., and have characteristics such as relatively low density and recyclable utilization, therefore obtained huge development in recent years.

Publication number be CN101474868A patent disclosure a kind of continuity strengthen thermoplas tic resin composite and preparation equipment, yet this material has certain limitation: 1, the unidirectional sheet material that goes out according to CN101474868A patent explained hereafter, its glass fiber content is difficult to reach 55%, and the 0-90 ° of product that bi-directional device is produced, glass fiber content can reach 75%, even surpasses; 2, fiber floods incomplete problem in thermoplastic resin, its consequence can directly have influence on the physical property and the mechanical performance of product and finished commodities, the patent key component of CN101474868A is the bimodulus head with the thermoplastic resin of fiber by extruding molten condition, walk " S " type technology impregnation of fibers, it can only or be close to die orifice by the pressure of the fiber tightened and one ejection molten resin of die head mouth and flood, and its product can not guarantee that every bundle fiber is all impregnated.

Summary of the invention

The technical problem to be solved in the present invention is: a kind of longitude and latitude overlapped non-weaving compound material is provided, has solved not high-technology problem of original composite physical property and mechanical performance.

The technical solution adopted for the present invention to solve the technical problems is: a kind of longitude and latitude overlapped non-weaving compound material, form by overlap the mutually dipping compacting of warp layer and parallel layer, the warp layer forms by warp is bonding, the parallel layer forms by parallel is bonding, and the angle angle between described warp and the parallel is 0～90 °.

The invention has the beneficial effects as follows, TENSILE STRENGTH of the present invention, some physical properties such as bending strength and mechanical performance all improve greatly, particularly 0-90 ° of two-way product horizontal, vertical two to having same physical property and mechanical performance, can satisfy the product of various high performance requirements.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is a side-looking structural representation of the present invention.

Fig. 2 is a plan structure schematic diagram of the present invention.

Among the figure 1, warp, 2, parallel.

The specific embodiment

In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.

A kind of longitude and latitude overlapped non-weaving compound material as shown in Figure 1, 2, form by overlap the mutually dipping compacting of warp layer and parallel layer, the warp layer is by warp 1 bonding forming, and the parallel layer is by parallel 2 bonding forming, and the angle angle between described warp and the parallel is 0～90 °.

The product that the present invention adopts 0-90 ° of bi-directional device to produce can solve the not saturating problem of the dipping of fiber in thermoplastic resin to a certain extent, guarantee that fiber fully floods at dipping tank, thereby product TENSILE STRENGTH, some physical properties such as bending strength and mechanical performance all can improve greatly, particularly 0-90 ° of two-way product horizontal, vertical two to having same physical property and mechanical performance, can satisfy the product of various high performance requirements.

Claims (1)

1. longitude and latitude overlapped non-weaving compound material, it is characterized in that: described composite is overlapped mutually to flood to suppress by warp layer and parallel layer and forms, the warp layer forms by warp is bonding, and the parallel layer forms by parallel is bonding, and the angle angle between described warp and the parallel is 0～90 °.
