Abstract

Boron doped carbon fibers reinforced lithium aluminosilicate matrix composites (C_f/LAS) were prepared by slurry infiltration combining with hot pressing procedure. The doping of boron significantly enhances the fracture toughness and fracture work of the C_f/LAS composites, which could reach the highest fracture toughness of 25.0 ± 0.4 MPa m^1/2 and the work of fracture of 24.5 ± 2.8 kJ/m², respectively. The work of fracture of boron doped C_f/LAS composites is 2.2 times of that of the boron free C_f/LAS composites. The fracture mode of C_f/LAS composites changed from ductile fracture to brittleness fracture with increasing the boron content from 0 to 4 wt%. The connection of the fracture behavior and the interfacial microstructure was examined to establish a direct relationship among interfacial microstructure, interfacial chemistry and fracture behavior of the studied composites.
