Problems solved by technology

The problem of dimensional deformation of the obtained non-woven fabric in the subsequent processing process has not been solved, and the influence of different raw materials on the forming strength of the sheet has not been mentioned
[0005] In addition, the above two patents both adopt the method of air-flow carding during carding, and the weight distribution in the width direction of the web-formed non-woven fabric is not uniform, resulting in a large standard deviation of the mechanical properties of the non-woven fabric in the width direction, resulting in the sheet material in the width direction. Variation in physical properties in terms of width becomes large, making it difficult to control the physical properties of products

Abstract

The invention discloses an automotive plate and a production method thereof. The plate is made of non-woven fabrics formed by mixing polylactic acid fibers with natural fibers, the strength of the polylactic acid fibers is higher than 1.4CN / dtex, the strength of the natural fibers is higher than 3.0CN / dtex, and the three-point bending strength of the plate is higher than 0.04N / 50mm / g / m<2>. The automotive plate has the advantages of high strength, fine dimensional stability, no environmental pollution and simple processing technology.

Description

technical field [0001] The invention relates to a sheet material for automobiles and a production method thereof, in particular to a sheet material for automobiles processed by hot pressing of high-strength non-woven fabrics and a production method thereof. Background technique [0002] At present, the use of natural plant fibers with the most abundant resources in nature to develop composite materials with excellent performance and low price has attracted people's attention. Natural plant fiber has excellent characteristics such as low price, light weight, high specific strength and specific stiffness, especially it is a renewable resource and a naturally degradable material, which is unmatched by other reinforcing materials. For example, the existing automotive interior products mostly use chemically synthesized materials, which are non-renewable and cause certain pollution to the environment after processing, and the strength of the obtained automotive interior products c...
