Glass fiber composite high-tensile fabric

Abstract

The invention discloses a glass fiber composite high-tensile fabric which is composed of a triaxial glass fiber composite fabric with the grams per square meter of 1215g and a biaxial glass fiber composite fabric with the grams per square meter of 800g, wherein the biaxial glass fiber composite fabric and the triaxial glass fiber composite fabric are bound together by binding yarns, and both the two glass fiber composite fabrics are formed by weaving epoxy glass fiber high-tensile yarns and polyester yarns. Only one layer of the glass fiber composite high-tensile fabric disclosed by the invention needs to be laid to achieve the effect of laying two layers of the triaxial glass fiber composite fabrics originally, thus obtaining a product which needs to be produced twice to meet the requirement of an impeller in the industry, avoiding material waste in use and improving the availability, the tensile strength and the tensile modulus. The glass fiber composite high-tensile fabric enables the produced impeller to meet the requirements of wind power generation equipment, can be used in the impeller of a large wind power generator of 1.5MW (40.3m), is mainly used in the whole body of the impeller, and ensures that the impeller has adequate longitudinal strength in the operating process.

Description

technical field [0001] The invention relates to a braided fabric of composite material, in particular to a high-strength braided fabric of glass fiber composite material. Background technique [0002] High-strength fiberglass fabrics are widely used in aviation, aerospace, wind power generation, automobiles, cruise ship manufacturing, oil pipelines and other industries. It can be made into high-strength FRP with resin. Compared with steel, the characteristics of FRP are: higher strength, lighter weight, and better corrosion resistance. [0003] In wind power generation, glass fiber fabric is the largest and most critical raw material in the manufacture of wind power blades. It is mainly used in megawatt-level wind power generators, such as: 1MW, 1.5MW, 2MW and other blades. [0004] Due to the requirements of the production process of the blade, the glass fiber fabric has several series of products such as uniaxial, biaxial, multiaxial, and unidirectional to complete the re...

AI Technical Summary

Problems solved by technology

[0005] 1: The material is seriously wasted during use, and the effective utilization rate is less than 77%, which increases the production cost

[0006] 2: In order to meet the needs of blades in the industry, the composite material fabric needs to be laid twice, which is time-consuming and labor-intensive, resulting in a production time of 35 hours for the entire blade, which reduces production efficiency
