碳纤维增强热塑性复合材料与钛合金焊接技术研究进展
Research progress in welding technologies of carbon fiber reinforced thermoplastic composites and titanium alloys
摘要
Abstract
Carbon fiber reinforced thermoplastic composites(CFRTP)show great application potential in aerospace and other fields owing to their advantages of light weight,high specific strength,rapid prototyping,and weldability.As a commonly used lightweight metal in the aerospace industry,titanium alloy is a material that can be directly bonded to CFRTP without corrosion defects.Achieving high-performance joining between the two is of great significance for reducing structural weight,cutting carbon emissions,and ensuring the operational safety of equipment.However,due to the differences in their physical and chemical properties,joining the two materials poses numerous challenges.This paper reviews the research progress on the welding of CFRTP and titanium alloy.It summarizes and analyses the process characteristics of various welding technologies,surface treatment methods of titanium alloys,and interface joining mechanisms.Furthermore,it looks forward to the common issues that need to be addressed in the welding of CFRTP and titanium alloys,aiming to provide a reference for the large-scale assembly application of CFRTP/titanium alloy hybrid structure.关键词
