Method for producing bamboo fiber composite material

Abstract

The invention discloses a method for producing a bamboo fiber composite material. The method comprises the following steps: 1, blending a bamboo fiber with a thermofusible fiber to prepare a yarn; 2, preparing a cloth from the yarn with a weaving technology; 3, compression molding: covering a thermofusible film with the cloth, laying in a die, hot pressing, stopping heating when the bamboo fiber and the hermofusible fiber are combined with the thermofusible film, cooling to 30-70DEG C, and stopping pressurization; and 4, removing a cooled substance from the die to obtain the bamboo fiber composite material. The composite material which is prepared through mixing the natural bamboo fiber with a thermoplastic in the invention and has the characteristics of certain environmental compatibility, light mass, high dimension stability, low cost, good processing performance, and less wearing to production equipment has wide application prospects in many fields. The tensile strength, the bending strength, and the impact strength (notch) of the bamboo fiber composite material of the present invention are greater than 29MPa, greater than 42MPa, and greater than 5.9K / Jm<2> respectively.

Description

technical field [0001] The invention relates to a composite material, in particular to a production method of a bamboo fiber composite material. Background technique [0002] my country is a country rich in bamboo resources but lacking in wood resources. Bamboo has the reputation of fast-growing forest in my country. Replacing wood with bamboo and making full use of bamboo resources is an important means to restore the natural ecological environment in our country. In recent years, with the acceleration of my country's industrialization process, bamboo products have received great attention and development, but the utilization of bamboo fiber composite materials still remains in the treatment of many bamboo product processing wastes. The emergence of bamboo fibrous bamboo fiber developed by Zhejiang Forestry University is an improvement in the utilization of natural bamboo resources, but how to make wider use of bamboo, improve the utilization rate of bamboo resources, impr...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a production method of bamboo fiber composite material, using hot-melt fiber and continuous bamboo fiber to form a reinforcing material as the structural phase in the fiber-reinforced composite material, and using long fiber three-dimensional textile structure preform as Reinforcement, hot-melt fibers are intertwined with bamboo fibers and form a matrix with the upper and lower coatings to form a composite material, which fundamentally eliminates whiskers, short fibers, particles, and unidirectional and laminated composites with low interlayer strength and easy separation. Layers, poor impact resistance, low cracking and damage tolerance and other shortcomings and shortcomings, greatly improve the strength and stiffness of composite materials, improve the toughness of composite materials, and the products can be used in fields that require higher mechanical properties
