摘　　要：采用不同含量与尺度的玻璃纤维(GF)填充丙烯酸树脂(AR)复合材料,研究了GF/AR复合材料的压缩强度和洛氏硬度。并通过热失重分析、结晶性能分析、宏观与微观形貌表征来探索其力学强度硬度变化的机理。结果表明,1 500目GF含量为40%,GF/AR复合材料的压缩强度和洛氏硬度最优;GF的含量变化对GF/AR复合材料的力学性能、热降解性能、XRD衍射峰强度和断面微观形貌均会产生明显影响且表现出规律性,GF的尺度变化有影响,但并不显著。In this thesis,acrylic resin(AR)composites filled with different contents and dimensions of glass fiber(GF)were used to study the compressive strength and Rockwell hardness.The mechanism of mechanical strength and hardness change were explored by thermogravimetric analysis,crystallization performance analysis,macroscopic and microscopic characterization.The results show that the GF contents of 1500 mesh is 40%,the compressive strength and Rockwell hardness of GF/AR composites are optimal.The mechanical properties,thermal degradation properties,X-ray diffraction(XRD)peak intensity and section of GF/AR composites are changed by GF contents.The microscopic morphology will have a significant impact and show regularity.The scale change of GF has an effect,but it is not significant.
