【摘要】 通过模压工艺制备了短切碳纤维/空心玻璃微珠(K46)/环氧树脂复合材料,并对复合材料的断面形貌、密度、抗压强度和吸水率进行了研究。研究结果表明,随着碳纤维含量的增加,复合材料密度变化较小,抗压强度上升,当碳纤维含量为4%时,抗压强度最大,微珠含量分别为50%、55%、60%的复合材料的抗压强度分别为68.9MPa、65.1MPa、57.2MPa;随碳纤维含量的增加,复合材料饱和吸水率下降,当碳纤维含量为4%时,微珠含量为55%、60%的复合材料达到最小饱和吸水率,分别为0.81%、1.15%。更多还原

【Abstract】 In this paper,a composite consisting of chopped carbon fiber,hollow glass microsphere and epoxy resin was prepared by molding process. The section morphology,density,compression strength,water absorption rate of the composite were studied. The results show that the density of the composite has little change,but its compression strength increased with the increase of carbon fiber percentage. When the carbon fiber content was 4%,the maximum compression strength of the composite with 50 wt%,55 wt%,60 wt% glass microsphere were 68. 9 MPa,65.1 MPa,57. 2 MPa,respectively. The saturated water absorption rate decreased as the increase of carbon fiber percentage. When the carbon fiber content was 4%,the composite with 55 wt% and 60 wt% glass microsphere show the minimum saturated water absorption rate of 0. 81% and 1. 15%,respectively.更多还原
