Three-directional non-yielding fiber cloth and production method thereof

Abstract

The invention discloses three-directional non-yielding fiber cloth. The three-directional non-yielding fiber cloth includes three fiber layers and connecting lines (4) which connect the three fiber layers, the three fiber layers include the 0-degree fiber layer (1), the 45-degree fiber layer (2) and the 135-degree fiber layer (3), the 0-degree fiber layer (1) is formed by fiber bundles which extend in the 0-degree direction, the 45-degree fiber layer (2) is formed by fiber bundles which extend in the 45-degree direction, and the 135-degree fiber layer (3) is formed by fiber bundles which extend in the 135-degree direction. The invention further discloses a production method of the three-directional non-yielding fiber cloth. The three-directional non-yielding fiber cloth and the productionmethod thereof have the advantages that the cloth is woven in a non-yielding mode, the connecting lines are adopted for bind, and combined with high strength of epoxy resin in a composite material repair process, the transverse and longitudinal strength of fiber material can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of fiber cloth structure, in particular to a three-way non-yielding fiber cloth and a preparation method thereof. Background technique [0002] Most of the existing fiber cloths are woven with fibers using a rapier machine. The fibers will be deformed during the weaving process, and there is a problem that the fiber bundles cross up and down. The cross folding will cause the strength of the fibers to decrease, resulting in performance attenuation and product strength reduction. And the traditional unidirectional fabric has high transverse strength but low longitudinal strength. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a three-way non-yielding fiber cloth with improved product strength and a preparation method thereof. [0004] The object of the present invention is achieved through the following technical solution...

Problems solved by technology

[0002] Existing fiber cloths are mostly woven with fibers using a rapier machine. The fibers will be deformed during the weaving process, and there is a problem that the fiber bundles cross up and down. The cross-folding will cause the strength of the fibers to decrease, resulting in performance attenuation and product strength reduction.
