摘要/Abstract

摘要： 选用TPU无纺布/碳纳米纤维膜作为复合材料外层保护层,采用树脂传递模塑(RTM)工艺制备无纺布/碳纳米纤维/玻璃纤维/环氧(NTPU/CNF/GF/EP)复合材料,并对复合材料的机械性能、耐固体粒子侵蚀磨损性能进行了研究。结果表明,直径为～500 μm的尖角碳化硅侵蚀颗粒,在侵蚀距离为76 mm、冲蚀角度为90°的条件下,对复合材料的侵蚀磨损破坏行为较强;一层100 μm厚NTPU的加入使复合材料的拉伸性能相比于GF/EP(FRP)降低了大约10%,耐固体颗粒侵蚀性提高了8倍;NTPU/CNF膜的加入可以有效地提高玻璃纤维复合材料的力学性能和御蚀性能。

Abstract: The excellent wear resistance of nonwoven thermoplastic polyurethane (NTPU)was chosen as shielding structure. Vacuum assistant spray method was used to fabricate the NTPU/carbon nonfiber (NTPU/CNF) composites,the GF reinforced epoxy (EP) composites toughened by CNF/NTPU was fabricated via resin transfer molding (RTM) process, meanwhile the mechanical properties and solid particle erosion resistance of composites were measured and compared to EP fiber reinforced plastics (FRP). The results show that, compared to FRP, one layer of 0.1 mm NTPU made the tensile strength of the NTPU/CNF/GF/EP composites decrease about 10%, and the solid particle erosion resistance increase by 8 times. Meanwhile, ~500 μm of eroded particles exhibited a maximum erosion rate after 30 seconds of erosion at distance of 76 mm from the spout and impingement angle of 90°.
