Blast performance of polyurethane foam-filled auxetic honeycomb ...
2024年6月15日 · This paper examines the impact of polyurethane foam (PUF) filling on the dynamic response of honeycomb sandwich beams (HSBs) through the blast testing. The HSBs are composed of steel face sheets and an aluminium alloy honeycomb core filled with PUF.
3D printed polyurethane honeycombs for repeated tailored …
2016年12月15日 · Thermoplastic polyurethane (TPU) honeycombs were designed and manufactured by fused filament fabrication 3D printing. The energy absorption capabilities of TPU honeycombs, with relative densities 0.18–0.49, were assessed. Compressive energy absorption behaviour of all structures was dependent on strain rate and cell orientation.
Development of microcellular thermoplastic polyurethane honeycombs with ...
2021年5月1日 · In this study, thermoplastic polyurethane (TPU) honeycombs with ordered macrostructure and microcellular lattice structure was fabricated via the integration of fused deposition modelling (FDM) and solid-state CO 2 foaming. The physical foaming induced and introduced the microcellular structure with cell size of about 2.77-12.27 mm into TPU ...
