Abstract:

In this Research effort, the tension-compression fatigue behavior of the 3D and 2D PMCs with 090 deg fiber orientation newly developed was investigated. These polymer composites consist of an NRPE high-temperature polyimide matrix with carbon fiber reinforcement. Compressive properties were assessed at 1 room temperature and 2 elevated temperature with one side, Tsub right, at 329 deg C and the other side open to the ambient air. Tension-compression fatigue tests were conducted at elevated temperature with a frequency of 1 Hz and a ratio of minimum to maximum stress of -1.
