Abstract The effects of microscale oil penetration on mechanical and chemical properties of carbon fiber-reinforced polymer (CFRP) composites were investigated to address the adverse effects of lubricating oil on lightweight composites and improve the oil-proof performance of composites. The CFRP composites were confirmed to have lower mechanical properties after impregnation with oil at elevated temperature due to microscale oil penetration in the vicinity of carbon fibers on the surface of epoxy composite, and a high resin content and high heat curing conversion of epoxy polymer could reduce the oil absorption and tensile strength reduction of CFRP composite.

微观渗油对碳纤维增强环氧复合材料力学和化学性能的影响

摘要 研究微尺度渗油对碳纤维增强聚合物（CFRP）复合材料力学和化学性能的影响，以解决润滑油对轻质复合材料的不利影响，提高复合材料的防油性能。由于环氧树脂复合材料表面碳纤维附近的微尺度油渗透，CFRP复合材料在高温浸油后具有较低的机械性能，并且环氧树脂聚合物的高树脂含量和高热固化转化率可以降低CFRP复合材料的吸油性和抗拉强度降低。
