Fiber product and manufacturing method thereof

Abstract

The invention discloses a fiber product which is characterized by comprising fiber bodies and connecting components arranged on the fiber bodies, wherein fiber plates, blanket products, or fiber plate-blanket product combinations are served as the fiber bodies; hook combinations or hook-loop combinations are served as the connecting components and arranged on one surface or both surfaces of the fiber plates or blanket products; the fiber bodies with the connecting components are immersed in a liquid matrix before or after being overlapped, so as to form three-dimensional fiber prepregs; and when a plurality of three-dimensional fiber prepregs are overlapped, the connecting components on the adjacent three-dimensional fiber prepregs are connected and firmly bound to form a three-dimensional composite. The invention further provides a manufacturing method of the fiber product. By adoption of the fiber product and the manufacturing method, the purpose of enhancing the mechanical strength, interlaminar strength, fatigue strength and impact strength of the three-dimensional composite can be fulfilled.

Description

[0001] This application is a divisional application for an invention patent application with an application date of October 26, 2007, an application number of 200710167767.3, and an invention title of "a fiber product and its manufacturing and application method". Technical field [0002] The present invention relates to a technology for reinforcing three-dimensional composite materials, specifically a fiber product and a method of manufacturing and application thereof. It relates to three-dimensional fibers, three-dimensional fabrics (including non-woven fabrics), three-dimensional predictions, three-dimensional prepregs and composite materials, and the use of Textile, non-woven industrial technology, hook and loop technology, plastic technology and nanofiber technology to manufacture the above-mentioned three-dimensional products. Background technique [0003] Although fiber composite materials are widely used in many industries, the low interlayer strength limits their use. The ...

AI Technical Summary

Problems solved by technology

[0003] Although fiber composite materials are widely used in many industries, the low interlayer strength limits the scope of application. The way to solve this problem is to improve the interlayer strength by three-dimensional weaving, weaving, knitting and interlayer sewing.

However, these three-dimensional technologies require complex machines and production processes, and are expensive, so layer-by-layer fiber stacking and fiber winding are still the main processes for composite material production

[0004] U.S. Patent No. 2717437, GDEMESTRAL, on September 13, 1955, introduced a Velcro technology, which is a layer or one side with a hook and loop connection element, used for buttons, zippers and other connectors. in that it cannot be stacked in multiple layers
