Mechanical and Electromagnetic Shielding Properties of Carbon Fiber Reinforced Multilayered(PyC-SiC) n Matrix Composites

Carbon fiber reinforcedmultilayered(Py C-Si C)n matrix(C/(Py C-Si C)n)com-posites were prepared by means of layer-by-layerdeposition of Py C and Si C and varying Py C-Si C se-quences via isothermal chemical vapor infiltration.Effects of the number of Py C-Si C layer(n=1,2 and 4)on the matrix microstructure,electri-cal conductivity,mechanical and

Carbon fiber reinforcedmultilayered （PyC- SiC） n matrix （ C/（ PyC -SIC） n） composites were prepared by means of layer-by-layer deposi- tion of PyC and SiC and varying PyC-SiC se- quences via isothermal chemical vapor infiltration. Effects of the number of PyC-SiC layer （n= 1, 2 and 4） on the matrix microstructure, elec- trical conductivity, mechanical and electromagnetic interference （EMI） shielding properties of C/ （PyC-SiC） n composites were investigated.
