Background
With the coming of the environmental protection and economic times, the composite material with low cost, good performance and certain environmental compatibility has wider and wider market prospect. In recent years, the advantages of natural plant fibers as reinforcing materials have been receiving increasing attention. Because it has the advantages of rich resources, low price, lower density than other inorganic fibers, and modulus and tensile strength similar to those of inorganic fibers, and also has the characteristics of repeated processing, difficult water absorption and moisture absorption, biodegradability and the like. Bamboo resources in China are rich and are called bamboo kingdom, and bamboo fibers as a class of plant fibers have the characteristics of the bamboo fibers, unique antibacterial and deodorant properties, excellent colorability and wear resistance, low cost and good plasticity.
The bamboo-plastic composite material is prepared by adding reinforcing material or filler in the form of bamboo fiber or bamboo powder into thermoplastic plastics, and heating to compound bamboo with molten thermoplastic plastics or by injecting organic monomer into the fine structure of bamboo, and then treating by radiation or catalyst method to make organic monomer and bamboo component produce graft copolymerization or homopolymer. The bamboo-plastic composite material fully combines the high-quality characteristics of bamboo and plastic, and has the advantages of good mechanical property, small material shrinkage and distortion, no pollutant generation and the like.

In addition, the complexity of the components of the bamboo fiber also determines the difficulty of the molding processing of the bamboo-plastic composite material, for example, as the proportion of the bamboo fiber increases, the processing fluidity and the mechanical property are reduced, and products with complex shapes cannot be produced. In addition, the obtained bamboo-plastic composite material has the defects of poor corrosion resistance, poor toughness, poor wear resistance, poor appearance and woody texture and the like.
