研究了经硅烷偶联剂处理碳纤维填充增强HPVC板材的力学性能,测量、分析了拉伸断裂面的分形维数,详细论述了数盒子法计算分形维数的原理和计算机的模拟过程。结果表明:经硅烷偶联剂KH550处理的碳纤维能与HPVC牢固地结合,当碳纤维填充量小于30%时,随着碳纤维加入量增多样条的拉伸强度增大;材料拉伸强度与断面视图的分形维数呈正线性关系。
The mechanical properties of HPVC sheets filled with carbon fiber reinforced with silane coupling agent were studied. The fractal dimension of tensile fracture surface was measured and analyzed. The principle of calculating the fractal dimension by digital box method and the computer simulation process were discussed in detail. The results show that the carbon fibers treated with silane coupling agent KH550 can be firmly combined with HPVC. When the amount of carbon fiber is less than 30%, the tensile strength of spline is increased with the addition of carbon fiber. The tensile strength and the cross-sectional view The fractal dimension has a positive linear relationship.
