Paper Title:
Energy Absorption of Ultra-High Molecular Weight Polyethylene Fiber-Reinforced Laminates at High Strain Rates
  Abstract

Some dynamic compressive tests about Ultra-High Molecular Weight Polyethylene Fiber-reinforced laminated Composites have been done using SHPB experimental system.The stress-strain curves of UHMWPE Fiber-reinforced Composites of three different laminated angles (0/90°, 0/90/45/-45°, 0/90/30/-60/60/-30°) are obtained at higher strain rates and their dynamic mechanical properties are also investigated at the same time.Based on all the stress-strain curves obtained, the characteristics of energy absorption of UHMWPE fiber angle-plied composites are analyzed and discussed.It is found that laminated angle has made little effect on the dynamic energy absorption of composites at higher strain rates.In addition,delamination and compaction in the thickness direction constitute the main dynamic failure mechanisms, which are studied by means of image analyses for the specimens after compression.
