A simplified model with periodicity space characteristics is presented to simulate interpenetrating network composites. The cutting process on this material is analysed by FEM. The results show that reinforced phase volume percentage(V%) has great effects on cutting deformation. When reinforced phase V% is larger, the cutting forces especially back force Fp fluctuate obviously which causes the whole manufacturing system to vibrate intensely.

Silicon carbide has suitable properties for high power electronic applications. We present here results on 6H-SiC bipolar diodes protected by Junction Termination Extension. We have achieved breakdown voltage of ~1200 V, which is close to the theoretical value, and forward current density of 120 A cm -2 at 5 V. Optical Beam Induced Current measurements and simulations have shown that JTE are very efficient and that their parameters are close to the optimum. Nevertheless, a little increase of their doping level should increase the breakdown voltage up to ~1400 V.
