Weave of composite material and method of preparation thereof

Abstract

A weave of composite material has a first weave and an X weave combined with the first weave. The X weave has multiple latitudinal fibers, multiple longitudinal fibers, and a woven center. Each longitudinal fiber is layered on two of the latitudinal fibers and then is woven through and layered under two of the latitudinal fibers. The longitudinal fibers are each woven by shifting in relative alignment position from one of the latitudinal fibers sequentially and woven radially with respect to a woven center, such that the longitudinal fibers form an X woven structure. Therefore, the intensity of the weave of composite material can be enhanced by the X weave with the X woven structure.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a woven product, especially to a weave of composite material and method of preparation thereof.[0003]2. Description of Related Art[0004]Generally, weave of composite material may be made of carbon fibers, glass fibers, aramid fibers, or other high toughness fibers, and include plain weave, unidirectional weave, or multidirectional weave. The weave of composite material is widely applied for the cases of portable electronic products to provide protection.[0005]With reference to FIG. 5, a plain weave 50 comprises multiple longitudinal fibers 51 and multiple latitudinal fibers 52. The longitudinal fibers 51 and the latitudinal fibers 52 are interwoven mutually and perpendicularly to form a one-layer structure. The plain weave 50 has a low production cost, but the intensity of the plain weave 50 is low, such that multiple plain weaves 50 have to be stacked and combined with each other to mai...

AI Technical Summary

Benefits of technology

The patent describes a special weave of material that is used as a base for other materials. This weave is made by weaving fibers in a way that enhances its elasticity. This weave is also made in a way that reduces stress concentration and warping, so it doesn't need to be layered with another weave to increase its strength. The weave is made using a controllable process that makes it relatively cost-effective. This weave is perfect for use in portable electronic devices.

Problems solved by technology

When the stress concentration occurs, the woven structure of the plain weave 50 is easily damaged.

Nevertheless, warping easily occurs on the stacked unidirectional weaves 60.

Yet the drawback is, the multidirectional weave 70 has a high production cost.

However, warping easily appears on the stacked plain weaves 50 and the stack unidirectional weaves 60.

The stacked plain weaves 50 and the stacked unidirectional weaves 60 have large thickness, such that adjusting the thickness to meet the demand of slimness for the portable electronic product is difficult.

On the other hand, when the plain weave 50 is forced with stress, the stress concentration of the plain weave 50 leads to structural damage easily.
