Developing thermoplastic hybrid titanium composite laminates (HTCLS) at room temperature: Low-velocity impact analyses

Hybrid titanium composite laminates (HTCLs) are high-performance light-weight fiber metal (FMLs) that being increasingly used in various industries such as aeronautical, military, and marine thanks to their optimized fracture toughness, impact resistance, thermal performance. In the current study, low-velocity (LVI) characteristics of a new generation thermoplastic (TP) HTCLs at energy levels investigated. To do so, Ti-6Al-4 V sheets, carbon fabrics, ultra-high molecular weight polyethylene (UHMWPE) fabrics fabricate multiple with different types, volume fractions, lamination layups. A low-cost resin infusion process is employed for manufacturing room temperature by using novel liquid methyl methacrylate resin, Elium® 188. Before fabrication, multi-step surface treatment method applied on Ti alloy sheets enhance interfacial properties between layer sheet. addition TP-HTCLs, equivalent thermosetting (TS) an epoxy Epolam, fabricated compare results evaluate possibility fabricating recyclable TP-FMLs enhanced out-of-plane properties. Impact including contact force, deflection, parameters, related damage modes investigated presented each laminate. It concluded newly developed TP-HTCLs can be cured have compared those TS-HTCLs. Besides, HTCL UHMWPE its sides (before sheets) performs better LVI fibers top bottom (of core) since exhibits higher strain failure toughness fibers.
