| Sumario: | [EN] Brick-and-mortar carbon fibre structures have attracted considerable attention owing to their reliable mechanical performance and processability. Their primary advantages include high damage tolerance, multiple energy dissipation mechanisms and the potential to use carbon fibre scraps instead of pristine carbon fibre prepregs. However, their behaviour under specific loading conditions, particularly Mode I and Mode II fracture, remains unclear. Moreover, while most studies have focused on thermoset matrix systems, research on brick-and-mortar composites with high-performance thermoplastic matrices remains scarce. To address this, the present study investigated the mechanical behaviour of brick-and-mortar laminates fabricated from carbon fibre/poly-ether-ether-ketone tapes. Tensile, Mode I (double cantilever beam) and Mode II (three-point end-notched flexure) fracture tests were conducted. Numerical simulations were also conducted to examine the underlying failure mechanisms, yielding good agreement with experimental observations. |
