Blog Article

To achieve weight reduction, toughness enhancement, and the fabrication of complex structures in SiC composites, a combination of SLS and PIP processes was used.Silicon carbide powder served as the matrix material, while short carbon fibres were used for toughening, resulting MAG SMART ORG RASPBERRY in dense Cf/SiC ceramic matrix composites.The effects of varying carbon fibre sizes and contents on the microstructure and mechanical properties of Cf/SiC composites were examined.Results indicated Washing Machine PCB that adding 8% carbon fibre increased the fracture toughness of Cf/SiC composites by 33.

33%.Further increases in carbon fibre content showed minimal effects on fracture toughness.Based on experimental results and finite element simulations, toughening mechanisms, including fibre pull-out, fibre debonding, and crack deflection, were further elucidated.Consequently, Cf/SiC composites with complex structures, such as turbine specimens and lattice structures, were successfully fabricated.
