摘　　要：采用压机压制工艺方法研制了T700/3234管件,对其进行了拉伸、压缩和弯曲试验。结果表明,T700/3234管件胶接长度对于拉伸试验结果影响较大,安装记忆合金环有助于提高管件的抗拉伸性能,有记忆合金环试样可承受的最大拉伸载荷较无记忆合金环试样提高10.1%;压缩性能试验单独管件与不加记忆合金的金属胶接后的管件对于压缩试验结果影响不大,记忆合金环有助于提高管件的抗压缩性能,有记忆合金环试样可承受的最大压缩载荷、压缩强度较无记忆合金环试样提高10.0%以上,但压缩模量较无记忆合金环试样无变化;有记忆合金环试样可承受的最大弯曲载荷可达20.433 kN,较无记忆合金环试样提高5.5%;为高性能碳纤维复合材料管件设计提供了依据。The T700/3234 pipes manufactured by hot press were presented in this paper. The tensile, compres- sive and flexural properties of the pipes were tested with or without memory alloy ring. The results show that the pipes with memory alloy ring have an increase of 10.1% on max tensile load, more than 10% on compressive load and compressive strength and 5.5 % on flexural load. The pipes with memory ring demonstrate an improvement of mechan- ical properties except for compressive modulus. The work of this paper establishes a reference for design of high per- formance carbon fibre composite pipes.
