Results show that the silane and macromolecule coupling agent could reform the interface of the wood fiber and pvc . the mechanical properties of the treated wood fiber / pvc composite compared with the untreated wood fiber / pvc composite improved . the wood fiber / pvc composite could not be regarded as structure materials , but it is a sort of light , low cost wood - plastic material 本文对木纤维进行了改性处理，研究了木纤维pvc复合材料的形态结构与力学性能，结果表明：硅烷偶联剂和大分子偶联剂混合使用能改善木纤维与pvc的界面粘接，经过偶联剂处理的木纤维pvc复合材料的力学性能较未处理木纤维pvc材料高，虽然木纤维pvc复合材料不能作为结构材料使用，但可作轻质低成本的木塑材料使用。
