摘要
分别添加0%、5%、10%、15%、20%、25%的玄武岩粉体和短切纤维,研究添加后木质复合材料关键力学性能的变化.当粉体添加质量分数为15%时,复合板的拉伸强度达到峰值24.3 MPa,比未增强的复合板高了94.3%;而玄武岩短切纤维添加质量分数为10%时,复合板拉伸强度达到峰值18.9 MPa,比未增强复合板提高50.8%.当粉体添加质量分数和玄武岩短切纤维添加质量分数均为10%时,复合板的弯曲强度达到峰值各为41.8 MPa和39.2 MPa,比未增强的复合板各提高了43.3%和34.4%.结果表明,玄武岩粉体不仅仅价格远低于玄武岩短切纤维,其增强效果也远优于该纤维.
The key mechanical properties change of wood composites was introduced when basalt glass powder and chopped basalt fiber with the different content （0%, 5%, 10%, 15%, 20%, 25%） were added in wood composites. The tensile strength reached a maximum value of 24.3 MPa when the adding content of powder was 15%. Compared with the unreinforced wood composite panel group, the reinforced group increased tensile strength 94.3%. However, the tensile strength value was 18.9 MPa when the addition ratio of chopped basalt fiber was 10%. Compared with the unreinforced one, the reinforced group only improved tensile strength 50.8%. The maximum bending strength value of 41.8 MPa and 39.2 MPa were obtained when the content of the powder and chopped basalt fiber were all 10%. Compared with the unreinforced one, the reinforced group increased bending strength 43.3% and 34.4% respectively. The results showed that the price of basalt glass powder was far below than chopped basalt fiber, and the enhancement impact of powder was far superior to reinforcing effect of the fiber.
