Fiber composites

The invention relates to the field of packaging materials, and provides a fiber-reinforced composite material with buffer and load-bearing properties. It is mainly composed of crude fiber and fine fiber compounded by an adhesive, in which the crude fiber is a tubular fiber with a length of 3-60 mm, the fine fiber is a fiber powder with a diameter of 10 to 60, and the weight ratio of the crude fiber to the fine fiber is 5 to 100: 100 At the same time, a molded packaging material made of the fiber composite material is provided. Mainly includes the shell layer, solid layer and floor layer. The solid layer adopts the fiber composite material provided by the present invention with buffer/load bearing properties. The molded packaging material is used for packaging of heavy products. The moulding packaging material provided by the invention can make heavy use of agricultural waste fibres, so the cost is low, and it is also an environment-friendly material, in particular it can meet the demand for heavy export product packaging materials.
