Design and development of hybrid composite bistable structures for energy absorption under quasi-static tensile loading

摘要: Abstract The composite bistable structures discussed in this paper consist of a material-based mechanism with saw-tooth strain/stress curve. They have more damage-tolerant behavior, and considerably higher strain-to-failure than the corresponding monolithic material. Past work showed successful results composites made ultra high molecular weight polyethylene (UHMWPE). This investigates number hybrid configurations, geometry manufacturing process inspired by previous work. Bistable designs are based on synergy two parts, main links waiting links, user-configurable balance strain, strength stiffness. In paper, carbon UHMWPE (Spectra®) hybrids studied terms their maximum strain specific energy. Considerably ductility was experienced for some while increased may be obtained principle layers those current
