Problems solved by technology

However, the mechanical properties of natural plant fibers are relatively poor, and when used as a reinforcement material, the performance improvement of the resin base is also limited. The literature (Composites Science and Technology, 2003, 63: 1287-1296) reports that jute is used as a reinforcement, polylactic acid As the matrix, the composite sheet was prepared by hot pressing, and the tensile strength was only nearly doubled.
[0003] Chinese patent 201010142221.4 discloses a polylactic acid fiber and hemp fiber composite material for automotive interior parts. The disadvantage is that the composite felt needs to be soaked in slurry, and the finished product is produced by two-step molding methods of hot pressing and cold pressing. The process is complicated and the composite material The strength is not greatly improved, and it is limited in applications with high mechanical performance requirements.
Its disadvantage is that the biodegradable resin polybutylene succinate used is still petroleum-based, not derived from biomass, and the fabric polyethylene terephthalate PET used is also derived from petroleum-based, not biological Degradable

Abstract

The invention relates to a composite fiber automobile interior board and a production method thereof. The automobile interior board comprises a base layer and a non-woven or woven surface layer which is laminated on the at least one surface of the base layer, wherein the base layer consists of the following composite fibers: first fibers, namely polylactic acid fibers, second fibers, namely bastose selected from at least one of jute fibers, sisal fibers, ramie fibers, linen fibers, hemp fibers and kenaf fibers, and third fibers, namely basalt fibers in a weight percentage ratio of (20-70):(10-60):(10-60); and the surface layer consists of polylactic acid fibers. The composite fiber automobile interior board can be made into a three-dimensional deep drawing high-strength automobile interior board, and is safe, firm and environment-friendly when used as the base material of an automobile door inner board and a ceiling.

Description

technical field [0001] The invention relates to an automobile interior trim panel, in particular to a composite fiber automobile interior trim panel and a production method thereof. Background technique [0002] Green, environmental protection and low carbon have become the key words for the development of automotive materials. Natural plant fibers have the advantages of low density, high specific performance, low price, abundant resources, and degradability. In recent years, natural fiber composite materials have attracted much attention. A lot of research work has been carried out at home and abroad, and some have been well applied in industry. However, the mechanical properties of natural plant fibers are relatively poor, and when used as a reinforcement material, the performance improvement of the resin matrix is ​​also limited. Literature (Composites Science and Technology, 2003, 63: 1287-1296) reported that jute was used as a reinforcement and polylactic acid was used...
