Ultra-high molecular weight polyethylene UHMWPE fibres

The materials selected used for this work are based in polypropylene (A), an Ultra-High Molecular Weight Polyethylene (UHMWPE) (B, C, D) and an aramid fibre (E, F, G, H, I, J, K). The UHMWPE based materials B and C are made by the same manufacturer the main difference between them is their weight. The material based on aramid fibres (K) is from a different manufacturer than the materials E, E, G, H, I and J. The difference between them (E, E, G, H, I and J) is the number of layers. 

Aerospace composite structures can also employ high-performance polymeric fibres such as the aramids Kevlar (DuPont) or Twaron (Teijin Twaron), poly(p-phenyl-ene-2,6-benzobisoxazole) (PBO) (Toyobo) and high-modulus polyethylene (PE) (Dynema, Certran and Spectra). Generally ultra-high-molecular-weight PE (UHMWPE) can be considered to be inert to most environments except that the service temperature is limited to <130 °C.
