Abstract:

By applying ultra-high molecular weight polyethylene fiber (UHMWPE) and aramid as reinforced fabric panels and flexible polyurethane (PU) as core, a sandwich flexible composite with good cushioning property was developed by textile technique and one-step foaming process. PU composites reinforced by nylon nonwoven and basalt plain weave fabric were prepared as control group, and static and dynamic mechanical testing were conducted on all three composites. The results show aramid/UHMWPE plain weave reinforced sandwich composite has excellent mechanical property. The tensile strengths and elongation at breaks of aramid/UHMWPE plain weave reinforced sandwich composite in longitudinal and horizontal direction are 1 930 N, 1 744 N, 5.8% and 6.5%, respectively. The sandwich composite is compact when the compressive displacement reaches to 7.5 mm, and the compressive deformation is 93%. Impact strength of aramid/UHMWPE plain weave reinforced sandwich composite is 1 260 N with absorbed energy of 13.4 J and energy density of 4.95 J/g, proving good energy absorption capability on the basis of lightweight.

Key words: ultra-high molecular weight polyethylene fiber, aramid, polyurethane, sandwich composite, mechanical property
