Overview

Experimental analysis shows high-performance polymer composites maintain integrity under cryogenic exposure, indicating durability for extreme environments.

Key Points

  • The study aims to evaluate the structural integrity of polymer composites under cryogenic conditions.
  • Fabrication of composites using poly ether-ether-ketone and various fibers through compression molding at 380°C and 2 bars.
  • Exposure of composites to liquid nitrogen for 5 days to assess mechanical properties.
  • Characterization of composites using scanning electron microscopy, thermal conductivity, and other analytical methods.
  • Para-aramid fiber composite exhibits only 10% loss in ultimate tensile strength under non-exposure conditions.
  • Modulus toughness degradation is lower for para-aramid fiber composite compared to others when exposed to cryogenic conditions.
  • Limited oxygen index of para-aramid fiber composite indicates good fire resistance potential.
