竹/塑复合材料力学性能评定及其应用

EVALUATION OF MECHANICAL BEHAVIOUR AND APPLICATION OF BAMBOO REINFORCED PLASTIC COMPOSITES

复合材料从利用天然材料到利用人工材料,从原始经验到高技术的发展,标志了材料发展史上,从第一代利用天然材料的复合材料到第四代先进复合材料的进程。先进复合材料性能优越,但高性能的碳纤维、芳纶纤维等造价高,影响了广泛应用。利用天然纤维采用新的复合工艺,制成性能良好而又价廉的复合材料,将是广泛应用于生产、生活的材料新品种。

This paper summarizes the work on a number of bamboo reinforced plastic composite materials (BRPs) developed by the authors. Their (BRPs) mechanical characteristics as well as microstructure were investigated. The exp-perimental evaluation shows that BRPs possess favorable properties. The effects of bamboo species, scale of reinforcement, constituent of matrix and processing condition on mechanical properties of BRPs are obvious. The reinforcing mechanism of bamboo/plastic is discussed. Bamboo/plastic is a new breed of materials which utilizes abundant natural bamboo resourse with reasonably gocd properties and low cost, and exploits a wide spectrum of applications.
