Embodiment 1

[0017] Step 1: Mixing

[0018] The dosage of each fiber in the core layer is as follows: 20kg of basalt fiber, 20kg of hemp fiber, 25kg of polyester fiber and 35kg of polypropylene fiber are uniformly mixed to make a mixture; the dosage of each fiber of the surface layer is as follows: 15kg of polyester fiber, 25kg of polypropylene fiber and 10kg of spandex fiber into a mixture;

[0019] Step 2: laying the net

[0020] The mixture made in the first step is spread out in sequence to make a core layer and a surface layer to make a composite substrate semi-finished product.

[0021] Step 3: Thermoforming

[0022] The composite base material semi-finished product is thermocompressed into a composite sheet product.

Embodiment 2

[0024] The dosage of each fiber in the core layer is as follows: 15kg of basalt fiber, 25kg of hemp fiber, 25kg of polyester fiber and 35kg of polypropylene fiber are uniformly mixed to make a mixture; the dosage of each fiber of the surface layer is as follows: 15kg of polyester fiber, 25kg of polypropylene fiber and 10kg of spandex fiber into a mixture;

Abstract

The invention relates to an environmental-friendly recyclable basalt fiber and jute fiber composite plate for automotive interiors and a production method thereof. The environmental-friendly recyclable basalt fiber and jute fiber composite plate is produced by manufacturing a felt by combining a surface layer with a core layer and then carrying out hot-press forming. The core layer is manufactured by lapping and needling two natural fibers, i.e. basalt fibers and jute fibers, and mixtures of two chemical fibers, i.e. polyster fibers and polypropylene fibers; and the core layer comprises the following components in percentage by weight: 10%-30% of the basalt fibers, 10%-30% of the jute fibers, 20%-30% of the polyster fibers and 30%-40% of the polypropylene fibers. The invention has the advantages of low density, light weight, low cost, high strength, good toughness, large deformation, high safety, environment friendliness, recyclability, and the like.

Description

technical field [0001] The invention relates to a composite board made of natural fibers and chemical fibers and mainly used for interior decoration of automobiles. Background technique [0002] With the rapid development of the automobile industry and the rapid increase of automobile ownership, people have higher and higher requirements for the quality and environmental protection of automobile interior parts. The materials for automotive interior parts are developing in the direction of green environmental protection and recyclability. The composite substrates currently used for the production of automotive interior parts are usually polyurethane (PU) boards, polypropylene (PP) wood powder boards, glass steel plates, etc. Due to the defects of toxic chemical pollution, the original PU board and PP wood powder board can no longer meet the needs of modern automobile development, and are gradually being replaced by natural fiber composite materials. The processing of natural...
