以微纤竹纤维（BF）和可生物降解聚乳酸（PLA）树脂为原料，采用热压法制备了绿色环保复合材料（GCs）。研究了高炉掺量对碳纤维弯曲性能和冲击能的影响。结果表明，添加高炉对气相色谱试样的弯曲性能和冲击能有较大影响。当高炉掺量大于或等于40%时，抗弯性能和冲击能均随高炉掺量的增加而增加，随高炉掺量小于或大于40%而减小。这是由于内部缺陷的存在，如空洞，观察到GC样品与少于或多于40%的BF质量增强。
Environment-friendly or "green" composites (GCs) made from micro-fibril bamboo fiber (BF) and biodegradable poly-lactic acid (PLA) resin were fabricated using a hot-pressing methods. The effect of BF content on the flexural properties and impact energy of the GCs was investigated. The results show that the flexural properties and impact energy of the GC samples are tremendously affected by the addition of BF. Both the flexural properties and impact energy increase with increasing the BF content up to 40% and then decrease with BF contents less or more than 40% by mass. This was because of the existence of internal defects such as voids was observed for the GC samples reinforced with less or more than 40% mass of BF.
