Novel engineering materials and structures are increasingly designed for use in severe environments involving extreme transient variations temperature loading rates, chemically reactive flows, other conditions. The Texas A&M University Hypervelocity Impact Laboratory (HVIL) enables unique ultrahigh-rate characterization, testing, modeling capabilities by tightly integrating expertise high-rate behavior, computational polymer chemistry, multi-physics multiscale numerical algorithm...
When developing protective structures to defend against hypervelocity impacts (HVIs), optimizing specific energy dissipation is critical. Incorporation of lightweight materials, such as polymers, into novel layered shielding concepts could improve HVI performance in space and military applications without compromising cost or weight. One key challenge a fundamental understanding the effects molecular architecture on macroscopic dynamic material response damage formation. In this work, two...
In this study, hypervelocity impact experiments were performed on both unstitched and through-thickness Vectran™-stitched laminates. Both laminate types fabricated from DMS-2436 class-72 warp-knit multiaxial carbon fabric, infused with API-1078 resin using a Controlled Atmospheric Pressure Resin Infusion (CAPRI) process. The laminates impacted by 4 mm diameter, spherical, Nylon 6/6 projectiles at nominal velocities of km/s two-stage light gas gun. primary measures the performance composite...
In-flight lightning strike damage to aircraft composite structures may compromise airworthiness. Hence, it is crucial incorporate adequate protection systems mitigate the current. Most (LSP) techniques involve bonding a metallic conductive layer cured laminate exterior. In this study, novel LSP integration technique was used develop unitized panels with three different layers: pitch carbon fiber paper (PCFP), graphene (GP), and copper mesh (CM). Each overlaid on through-the-thickness...
