Coconut fiber composite material for automotive interior material and preparation method of coconut fiber composite material

The invention provides a coconut fiber composite material for an automotive interior material and a preparation method of the coconut fiber composite material, and belongs to the technical field of automotive interior materials. The invention provides a coconut fiber composite material for an automotive interior material. The coconut fiber composite material comprises a coconut fiber felt layer, wherein the coconut fiber felt layer is a dense felt material which is formed by opening, scattering, fully mixing and carding coconut fibers and oil/oil-free polypropylene short fibers to form a fiber net, and then needling the fiber net to form the fiber net, wherein the coconut fibers and the oil/oil-free polypropylene short fibers are hooked together. The coconut fiber composite board produced from the coconut fibers and the oil-free polypropylene short fibers is resistant to corrosion, free of mildew, antibacterial, breathable and low in price, and compared with a composite material produced from hemp fibers or g
