摘要

碳纤维复合材料（CFRP）与金属合金的叠层结构材料常应用于航空航天等领域的制造过程中，其中CFRP与钛合金（Ti）的叠层材料的应用较为广泛。在CFRP/Ti叠层材料的钻孔工艺中，由钻削热引起的在两材料相接触的界面处出现的加工缺陷较为显著，故对影响此类材料钻孔加工过程中的界面温度的主要因素进行了研究。设计了借助热电偶测定CFRP/Ti叠层材料钻削过程中界面温度的试验，在试验中改变了加工参数及超声辅助参数。获得了加工参数对界面温度的影响规律，同时确定了超声辅助加工对界面温度的改变规律。

Abstract

Carbon fiber reinforced plastics (CFRP) and alloy stacked materials are used in the manufacturing process in the fields of aerospace. And the CFRP/Ti stacked material is widely used. The processing defects caused by heat are more significant in the drilling of CFRP/Ti stacked material

and mostly appear at the interface where two materials are in contact. Therefore

the main factors affecting the interface temperature in drilling of CFRP/Ti stacks are studied. The experiment of the interface temperature monitoring in the drilling of CFRP/Ti stacks with the help of thermocouples is designed. The processing parameters and ultrasonic assistance parameters were changed in the experiment. The primary object of this study is investigating the relationship between processing parameters and interface temperature in the variable parameters drilling of CFRP/Ti stacks

and the influence of the ultrasonic is also discussed.
