Abstract

The invention discloses a preparation method of three-dimensional in-plane quasi-isotropic sewn fabric. The method comprises the following steps that n pieces of cut cloth are alternately layered andthen fixed on sewing equipment through a fixture; a machine needle is inserted into the cloth to be sewn and pierces the cloth, and a needle tube is placed on the needle tip of the machine needle andpushed into a needle hole to eject the machine needle out; the machine needle moves along the x axis at equal intervals, and the operation is repeated until the placement of a row of needle tubes is completed; a manual sewing needle with z-directional yarn penetrates into the needle tube close to the edge to eject the needle tube out, the z-directional yarn is tensioned, then the manual sewing needle penetrates into the second adjacent needle tube to eject the second needle tube out, the z-directional yarn is tensioned, the operation is repeated until the needle tubes of the whole row are replaced, punching is repeatedly conducted, a needle tube is placed to eject the machine needle out, and the manual sewing needle penetrates in to eject the needle tube out for sewing until the whole piece of cloth is sewn. Compared with a traditional method, the preparation method has the advantages that the needle tubes are introduced, the fraction of the yarn is reduced, and the friction breakage of the high-performance yarn in multiple times of sewing is avoided.

Description

technical field [0001] The invention belongs to the technical field of materials and textiles, and relates to a preparation method of a quasi-isotropic stitched fabric in a three-dimensional plane. Background technique [0002] Fiber-reinforced composite materials have the advantages of high specific strength and specific modulus, strong designability, and good fatigue resistance, and are widely used in various fields such as aerospace, medical equipment, and sporting goods. As the main structural form of fiber-reinforced composites, laminates have good in-plane mechanical properties and flexible designability, and have been used in shipbuilding, aerospace, and automobile manufacturing for many years. However, due to the lack of through-thickness reinforcing fibers, the through-thickness properties of laminates are determined by the lower performance resin and fiber-resin interface, resulting in poor interlayer bonding, low interlaminar strength, and weak resistance to delam...
