| 摘要 |
A novel thermoplastic composite material which is reinforced with "hemp fibers" and which shows high impact strength, high tensile strength, high bending modulus and high heat deformation temperature. This composite material is obtained by mixing fibers of hemp such as ramie, flax, hemp, jute, Manila hemp or sisal hemp with a wooden material such as wood flour or wood particles to prepare a homogeneous mixture, adding thereto a thermoplastic matrix such as polypropylene or polyethylene, well mixing the total components to homogeneously disperse the hemp fibers and the wooden material in the matrix and form composite particles. The composite particles are then formed into sheets adapted for stamping or pellets adapted for injection molding or transfer molding. |
