Microstructure and mechanical properties of bio-inspired Cf/Ti/Mg laminated composites

Inspired by an old fish skin structure, the Cf/Ti/Mg laminated composites were fabricated by squeeze casting technology. No porous or voids were found in final composite, and carbon fiber was uniformly dispersed in Mg matrix. Furthermore, the addition of net-shaped Ti adsorbed Al element and facilitated the nucleation of Mg17Al12 nearby Ti. The reaction product Al4C3 was found at the Cf and AZ91 interface. Mechanical tests indicate that the introduction of Ti could greatly improve the toughness of Cf/Mg composites.
