Problems solved by technology

However, the mechanical properties of natural plant fibers are relatively poor, and when used as a reinforcement material, the improvement of the performance of the resin base is also limited.
On the other hand, the heat resistance of natural plant fibers is poor, and the processing temperature should not be too high or too low. If the temperature is too high and exceeds 250°C, the hemp fiber will easily burn and deteriorate. If the temperature is too low and below 150°C, the hemp fiber will not soften easily. , poor processability, making the choice of resin base material more stringent

Abstract

The invention relates to an automotive internal decorative plate composite material and a production method thereof. The automotive internal decorative plate composite material comprises a base layer, and non-woven / woven surface layers which are laminated on at least one surface of the base layer, wherein the base layer is made from the following composite fibers: first fibers, second fibers and third fibers; the first fibers are polylactic acid fibers; the second fibers are selected from at least one of jute fibers, sisal fibers, ramie fibers, linen fibers, hemp fibers and kenaf fibers; and the third fibers are basalt fibers; and the weight percentage of the first fibers to the second fibers to the third fibers is (20-70) to (10-60) to (10-60). A surface layer is made from the polylactic acid fiber. The composite material disclosed by the invention can be used for preparing a high-strength automotive internal decorative plate capable of three-dimensional stretching; and the material is safe, firm and green when being used as an inner plate of an automotive door and a base material of an automotive ceiling.

Description

technical field [0001] The invention relates to a composite material for an interior trim panel of an automobile, in particular to a composite material for an interior trim panel of an automobile and a production method thereof. Background technique [0002] Green, environmental protection and low carbon have become the key words in the development of automotive materials. Natural plant fibers have the advantages of low density, high specific performance, low cost, abundant resources, and degradability. In recent years, natural fiber composites have attracted much attention. A lot of research work has been carried out at home and abroad, and some of them 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 improvement of the performance of the resin base is also limited. On the other hand, the heat resistance of natural plant fibers is poor, and the processing temp...
