Problems solved by technology

However, in the general vacuum adsorption process, the guide cloth needs to be removed after the product is cured, so it is necessary to place a release cloth between the product and the guide cloth, which plays a very important role in the smooth implementation of the pro

Abstract

This invention relates to a river diversion fiberglass cloth and its method of vacuum adsorption, the river diversion fiberglass cloth mainly comprises radial fiberglass yarns (11); zonal fiber glass yarns (12) and stitching organic fiber yarns (13), the two former are laid up-down one another, laid down straightly and parallel to each other, and then stitch through stitching organic fiber yarns perpendicular to the plane of the cloth. The river diversion cloth of the invention can guide resin flow rapidly and penetrate. As river diversion cloth and the molding products have the same composition, and do not need to be removed after curing and solidification of products, the river diversion cloth can enhance the strength and stiffness of structure, the river diversion cloth reduces the cost, improves process efficiency and product quality. The invention can be used as structural components of large-scale composite, and will also highlight its merits and effectiveness.

Description

technical field [0001] The invention relates to a flow-guiding structure composition of glass fiber cloth and a vacuum adsorption method using the cloth, especially the glass fiber cloth with the flow-guiding structure composition, which can guide resin to flow and penetrate quickly. The use of this cloth can ensure fast and high-quality completion of the vacuum impregnation and curing process of the resin during the specified vacuum adsorption process. Background technique [0002] At present, a common process method for manufacturing large-scale or complex-shaped glass fiber-reinforced resin-based composite structural members is to remove the gas in the fiber reinforcement in a vacuum state, and use the flow and penetration of the resin to achieve rapid and high-quality The fibers and their fabrics are impregnated. That is, a single-sided rigid mold is used to lay reinforced fiber materials on it, and then sealed with a vacuum film, and the resin is impregnated with fiber...
