The four stress-strain plots compare compressive behaviour of Onyx, G F F slash Onyx, K F F slash Onyx, and C F F slash Onyx composite materials under dynamic and quasi-static loading conditions. The x-axis represents strain, and the y-axis represents stress in megapascals. Each subplot contains multiple solid and dashed curves representing repeated tests and loading conditions. Onyx exhibits lower stress capacity and earlier softening behaviour, while fibre-reinforced composites display pronounced strain hardening and substantially higher stress resistance. K F F slash Onyx and C F F slash Onyx achieve peak stresses exceeding 140 megapascals at high strain levels, whereas G F F slash Onyx demonstrates intermediate strengthening behaviour with smoother stress progression.Stress–strain curve of gyroid: (a) Onyx; (b) GFF/Onyx; (c) KFF/Onyx; and (d) CFF/Onyx subjected to compression at quasi-static (2 mm/min) and dynamic (4 m/s) loading velocities
