•We develop biomimetic designs of the human annulus fibrosus.•We propose lattice structure with specially designed octagonal cells patterns.•We introduce hydrogel as matrix reinforced by polylactide fibers.•We model hydrogel time-dependent response in relation to polylactide features.•We show a perf...
