Interpenetrating Phase Composites (IPC) belong to a special category of composite materials, offering great potential in terms of material properties due to the continuous volume structure of both composite components.
Composite materials are categorized according to the type of their reinforcement, being particle, fibre or interpenetrating reinforcements.
Resonant frequency damping analysis are carried out in cooperation with RWTH Aachen University, Division of Materials Science and Engineering.

Preparation and Properties of SiC Porous Ceramics Made by Oxidation-bonding Technique Hongfang Li1, a, Yi Xia2, b and Hongling Zhao2, c 1Dept. of Civil Engineering, Luoyang Institute of Science and Technology, Luoyang, China; 2College of Materials Science and Engineering, Henan University of Technology, Zhengzhou, Henan, China alihongfang1976@163.com, bxylirr@yeah.net, czhaohn2007@163.com Keywords: SiC porous ceramics, Oxidation-bonding technique, Carbon content.
The SiO2 glass phase or mullite is produced during oxidation and they endow the materials high strength.
Experimental Using high pure SiC powder (180 mesh，320 mesh，800 mesh), carbon black powder (C), uf-Al2O3 as main raw materials, carboxymethyl cellulose (CMC) as the binding material.
But the surface of the materials treated at 1450°C is severely oxidized.
There appeared needle-like materials in SiCC30, SiCC40 and SiCC50 after treated at 1350°C, and these needle-like materials gradually decrease with the increase of C content.

Thermoelectric (TE) materials were considered as the best at converting waste heat to electricity.
With these regards, Co-based oxide materials with layered structures are possible candidates for TE materials[4-6].
Hence, researchers endeavored to find polycrystalline materials with high ZT value.
