In this study, PMI foam and aluminum are used as reinforcement materials for filling the cells of carbon fiber-reinforced composite square honeycomb sandwiches (CSHSs), forming two new sandwich structures, namely, foam-reinforced CSHS (PRCSHS) (AFRCSHS). The impact resistance residual flexural performance composites is compared by using low-velocity (LVI) three-point bending (3 PB) experiments. different energy levels 25 J, 50 65 100 J applied. failure process mechanism analyzed a...
In urban combat, sub-millimeter inert metal powder is used to replace fragments in explosive bombs, which can effectively reduce collateral damage. order investigate the damage effect of high-speed particles on human body, a particle ring filled with charge was designed create an explosion-driven cloud for penetration ballistic gelatin. The made polytetrafluoroethylene (PTFE) and tungsten powder. dispersion properties driven by explosion were studied photography Furthermore, numerical...
A composite multifunctional radar absorption polymethacrylimide (RAPMI) foam sandwich (MRAPS) was constructed. Analytical models for out-of-plane and in-plane compression of the MRAPS were established. Three-dimensional failure mechanism maps specific strength cubic cloud drawn. Finally, a multiobjective particle swarm optimization (MOPSO) algorithm used to achieve an integrated design, calculation example tested verified through experiments. The resulting with 43.0 mm thickness core 0.13...
Abstract In this study, aluminum honeycomb cells were filled with polymethacrylimide (PMI) foam of high strength and stiffness, carbon fiber reinforced composite (CFRC) skins added to create a sandwich structure. Nine types specimens varying cell node spacing density constructed, stiffness equations derived. To compare the performances PMI structures, their compressive responses examined using edgewise flatwise compression tests. Moreover, failure was analyzed finite element methods (FEM)....
Abstract This article reports a carbon fiber–reinforced plastic Kagome composite honeycomb sandwich structure reinforced with polymethacrylimide (PMI) foam (PKCSS). Low‐velocity impact performances on the node, rib, and two cell centers of PKCSS were experimentally compared those (CKHS), failure mechanism was investigated. The process analyzed through an explicit numerical analysis using ABAQUS. A three‐dimensional Hashin criterion introduced VUMAT subroutine. Results confirmed that exhibits...
Abstract This article presents a new radar‐absorbing polymethacrylimide (RAPMI) foam, measures the electromagnetic (EM) parameters of and establishes mechanical prediction models. The reflection loss (RL) curves foams with different thicknesses absorbent weight ratios (wt%) were analyzed along shear compression behaviors RAPMI foam. Gibson models foam then established. parametric effects absorption performance multilayered using multimedia transmission‐line theory. A numerically designed...
