High strength/high modulus fibers were prepared from polyethylene (PE) by melt spinning/hot drawing process. The fibers displayed an improved mechanical properties with increasing draw ratio. Modulus and tensile strength up to 35.6 GPa and 1.13 GPa, respectively, were obtained. All fibers displayed very similar work of rupture although their % elongation at break decreased with increasing draw ratio. These PE fibers were pressed into cross-ply composite by film stacking process. The composite displayed much higher puncture impact strength than isotropic PE.
