Impact Resistance of Polyethylene Hybrid Composites

摘要

The instrumented impact test was used to elucidate a relation between the impact properties and hybridization of ultra-high strength polyethylene and composites of either glass or graphite fiber. Impact resistance in composite is substantially improved by addition of PE fibers. Penetration resistance is also improved when the composite is hybridized. Stacking sequence of the hybrid composites' layers is an important factor in determining the actual amount of energy that will be absorbed prior to failure. Characteristic fracture mechanisms of the alternating stacked composites is penetration and delamination of the sample. Impact resistance, Polyethylene, Hybrid composites. Reprints. (jes)
