Abstract Carbon fiber reinforced polymer (CFRP) auxetic composite structures have attracted an increasing attention in recent years due to their lightweight and superior mechanical properties compared with traditional structures. However, most of the reported all‐CFRP are often accompanied cliff‐like stress drops during failure process, resulting lower energy absorption. This paper reports design, fabrication characterization a novel type petal‐like lightweight, high‐strength, good absorptive properties. Four uniform/gradient were first made different angle values continuous CFRP composites. Then, properties, Poisson's ratio mechanism under quasi‐static compression loading analyzed. Based on experimental results, gradient structure constructed cells varying angles was further selected study its dynamic response initial impact energies positions. The results show that composites can maintain even large deformation. Impressively, these exhibit plateau phase compression, indicative exceptional absorption capabilities. low velocity point tests also displacement peak number peaks load–displacement curves significantly influenced by changes position energy. research offers valuable insight into developing fabricating characteristics. Highlights Auxetic high EA capacity designed fabricated. Their static loads studied. significant performance. exhibits abundant forms.

Auxetic laminates, i.e. with a negative Poisson’s ratio (NPR), show great engineering promise, enhancements in shear resistance, fracture toughness, energy absorption, and delamination damage extension limitation. This study focuses on the tensile properties of in-plane (IP) NPR fibre-reinforced polymer (FRP) namely carbon/epoxy (C/E) carbon-glass/epoxy (C-G/E) lay-up sequences which maximised effect. An analytical was conducted to achieve maximum sequences. Laminates were manufactured via hand hot compression moulding techniques. ratios −0.33 −0.18 achieved for C/E C-G/E IP auxetic lay-ups, respectively. A 72% reduction longitudinal stiffness between unidirectional (UD) sequence verified, further 24% from configurations due less anisotropy G/E plies. Regarding strength, showed low failure strengths, 1213 MPa UD case, 209 studied laminates. alternative design analytically incorporation 0° layers sequences, improved stiffness, albeit at auxeticity. Further research is recommended explore influence enhancements.

Abstract The vibration modals of composite sandwich cylindrical shells with auxetic honeycomb cells arrayed in the circumferential direction and axial were studied theoretically numerically. equivalent moduli relative density cores derived validated. Subsequently, differences these physical quantities caused by number layers taken into consideration. Based on works, a verified third order shear deformation theory (TSDT) was applied to deduce free governing equations shells. Specially, effects deepness terms not ignored. To prove accuracy theory, four finite element modellings different numbers established for analysis. Additionally, modeled verify theory. frequencies calculated good fit those obtained from numerical method. Thus, influences dimensions discussed TSDT. sensitivity analysis showed that layers, radius shells, thickness had great influence Highlights deduced Effects stiffnesses core considered. modal studied.
