Abstract:The T700/3234 pipes manufactured by hot press were presented in this paper. The tensile, compressive
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 mechanical
properties except for compressive modulus. The work of this paper establishes a reference for design of high performance
carbon fibre composite pipes.
