Abstract

The invention relates to a composite material for manufacturing an automotive interior trim part. The bamboo fiber composite base material for manufacturing the automotive interior trim part is prepared by taking thermoplastic synthetic fibers (polypropylene PP, polyethylene PE or polyester PET and the like) as a bonding substrate and bamboo fibers as a reinforcing material through hot pressing. The bamboo fiber composite base material is characterized in that the bamboo fibers are prepared by sawing natural bamboo into pieces with length required by production, removing parenchyma from the bamboo by mechanical, physical, chemical and biological methods and directly extracting vascular bundle bamboo fibers from the bamboo, and have the length of 60 to 150mm, the diameter of 0.3 to 1.5mm, the strength of 60 to 120MPa and the water content of 10 to 12 percent. The automotive interior trim part can be subjected to press forming when the bamboo fiber composite base material covers artificial leather, leather or a knitted or non-woven fabric for surface decoration.

Description

technical field [0001] The present invention relates to a kind of composite material of automobile interior trim and its manufacturing method, especially a kind of composite material of automobile interior trim with bamboo fiber as reinforcement material and thermoplastic synthetic fiber as matrix, and the composite material of automobile interior trim The manufacturing method is mainly applicable to the manufacture of automotive interior parts. Background technique [0002] As people's awareness of environmental protection grows, people's requirements for the quality of automotive interior parts are also getting higher and higher. Lightweight and environmental protection have become an important trend in the development of today's automotive industry. In order to replace the application of metal materials and plastics in automotive interior parts. In recent years, the research and development of natural plant fiber composite materials has begun at home and abroad. Th...
