Fiber continuous forming process based on composite chain preparation

Abstract

The invention discloses a fiber continuous forming process based on composite chain preparation, and relates to the field of fiber processing, the fiber continuous forming process comprises the following steps: S1, glass fiber, carbon fiber and polyurethane resin fiber are bundled and woven to prepare a pre-impregnated material; s2, carrying out melting treatment on the pre-impregnated material, and carrying out melt impregnation; uniformly mixing the dried components according to the proportion, and putting the mixture into a premixing device for high-temperature melting; s3, rolling the pre-impregnated material in the molten state to prepare a composite blank pre-impregnated belt; and S4, the composite blank prepreg tape sequentially passes through a forming mold, a heating mold and a cooling mold under the cooperation of a traction device, and finally continuous forming is conducted. Under the condition of room temperature, the continuously formed glass fiber has the characteristics of good strong acid resistance, strong alkali resistance and high-concentration salt resistance, the mechanical property loss is less in a damp-heat aging experiment, and the glass fiber has good aging resistance; the linear shrinkage rate is small, and the deviation from the design size is very small.

Description

technical field [0001] The invention relates to the field of fiber processing, in particular to a continuous fiber forming process based on composite chains. Background technique [0002] As an inorganic fiber with excellent performance, glass fiber is a brittle material with high elastic modulus, high tensile strength and low elongation at break, and has the advantage of designable mechanical properties. With the rapid development of market economy, glass fiber is widely used in construction, transportation, electronics, electrical appliances, chemical industry, metallurgy, environmental protection, national defense, aerospace and other industries. Due to the continuous expansion of the field of glass fiber, it has attracted widespread attention. [0003] The continuous molding process refers to the entire process from the input of raw materials, through dipping, molding, curing, demoulding, cutting, etc., to the final finished product, which is carried out continuously. ...

AI Technical Summary

Problems solved by technology

[0006] In the existing continuous molding process of glass fiber, due to the relatively single component of the existing glass fiber and the lack of reinforcing materials, the mechanical properties and corrosion resistance of the prepared glass fiber are relatively weak. Therefore, it is necessary to propose a A new fiber continuous molding process to improve the mechanical properties of the produced glass fibers
