摘要:选取6种不同木质纤维制备PVC木塑复合材料，分析木质纤维的基本形态参数及表面接触角，对比研究不同木质纤维制备木塑复合材料的综合力学性能。结果表明：木质纤维长度、长径比及接触角值均较高的材种较适合制备木塑复合材料；在6种不同木质纤维中，纤维长度、长径比和接触角分别为266mm、6535和9032°的杉木制备的木塑复合材料综合力学性能最佳，弯曲强度、弯曲模量、拉伸强度和抗冲击强度分别可达4563、3247、2914MPa和641kJ/m2。 |

| Abstract: | The PVC based wood plastic composites (WPC) were prepared by six different wood fibers. The basic shape parameter and surface contact angle of each wood fiber were estimated, and tested the comprehensive mechanical properties for different WPC including flexural strength, flexural modulus, tensile strength and impact strength. The results showed that the mechanical properties of WPC were better when the values of length, length-diameter ratio and contact angle of wood fiber were higher. The best mechanical strengths were found on the WPC made by Cunninghamia lanceolata, its values of flexural strength, flexural modulus, tensile strength and impact strength were 45.63 MPa, 3247 MPa, 2914 MPa and 641 kJ/m2. |
