Problems solved by technology

[0012] At present, the production of pultrusion uses chopped glass fiber stitched mat. The strength of both mat and FRP products is relatively low. For products with high strength requirements, chopped stitched mat cannot meet the requirements, and continuous glass fiber is used. The price of felt is too high

Abstract

The invention belongs to the technical field of non-woven reinforcing materials, and in particular relates to a production device and a production method of a continuous glass fiber stitched mat. The continuous glass fiber stitched mat production device includes a creel, a creel, a yarn dividing device, and a spinning head that are connected in sequence. A conveyor belt is installed under the spinning head, and a yarn pressing device is installed above one end of the conveyor belt. The conveyor belt, The transition plate, the sewing machine head, and the pulling roller are connected to the coiler in sequence, and the sewing machine head is connected to the stitching line pan head. The continuous glass fiber precursors are led out from the creel and enter the spinning machine head through the spinning device. The spinning machine head sprinkles the continuous glass fiber precursors on the conveyor belt to form a mat, and the conveyor belt conveys the felt tire through the yarn pressing device. The felt tire is thinned, and the thinned felt tire passes through the transition plate and enters the sewing machine head for sewing and forming, and then enters the coiler through the pulling roller for framing coiling. The invention has the advantages of large output, high production stability, stable quality and low production cost.

Description

technical field [0001] The invention belongs to the technical field of non-woven reinforcing materials, and in particular relates to a production device and a production method of a continuous glass fiber stitched mat. Background technique [0002] Conventional continuous glass fiber mat is a non-woven reinforcement material, mainly used in various FRP mechanical forming, such as pultrusion, resin transfer molding (RTM), winding, high-performance SMC, etc. Continuous felt has excellent performance, good isotropy, higher tensile strength and bending strength than chopped strand felt, good migration resistance, and resistance to resin erosion; in the RTM process, high-pressure resin felt will not be deformed; impregnation Good, easy to cut, good mold coverage, good flow conductivity, high surface finish, especially suitable for high-performance, high-strength composite products. [0003] There are two production methods of continuous glass fiber mat: one is one-step method, t...
