CFRP/钛合金叠层构件低温钻削的轴向力与成孔质量研究
|
摘要
CFRP和钛合金叠层构件以其优异的性能广泛应用于航空、航天、汽车等领域。二者由于材料加工特性的差异,需要采用不同的钻削工艺参数才能获得满意的加工质量。为保证孔同轴度和加工效率,通常采用同一参数一体钻孔。一体钻孔会导致孔的界面烧伤、复材表面划伤、孔径一致性差等问题。为解决上述问题,提出一种低温钻孔工艺,通过钻削试验,研究低温条件下CFRP/钛合金叠层构件钻孔的轴向力、孔径一致性和表面质量。试验表明,低温条件下CFRP/钛合金叠层构件钻孔的轴向力增加,孔径一致性和表面质量均得到改善,证明了低温下CFRP/钛合金叠层构件一体钻孔的可行性。
Carbon fiber reinforced plastics(CFRP) and titanium(Ti) stacks are used widely in aviation, aerospace,automobile and other fields owing to the excellent performance. Because of the difference of material processing characteristics, different parameters are applied in drilling process of CFRP and Ti for satisfactory processing quality.However, CFRP and Ti are usually drilled together for the coaxiality of holes and machining efficiency. There are a lot of problems when drilling CFRP/Ti stacks, such as interface burns of holes, scratch of CFRP and the worse aperture consistency. In order to solve the above problems, a low temperature drilling process was proposed, and the drilling thrust,aperture consistency and surface quality of CFRP/Ti stacks in low temperature were studied by drilling experiments. The results show that the thrust force of CFRP/Ti stacks increases while aperture consistency and surface quality are improved in low temperature, which prove the feasibility of drilling CFRP/Ti stacks in low temperature.
