Effect of Interphase Thickness on Damping Behavior of 2D C/SiC Composites Qing Zhanga, Laifei Chengb, Wei Wang, Xi Wei, Litong Zhang, Yongdong Xu National Key Laboratory of Thermostructure Composite Materials, Northwestern Polytechnical University, PO Box 547, Xi'an 710072, China a coco195@163.com, bchenglf@nwpu.edu.cn Keywords: C/SiC composites; damping behavior; interphase thickness Abstract: Internal friction of 2D C/SiC composites fabricated by chemical vapor infiltration (CVI) method was measured by dynamical mechanical analysis (DMA) at different frequencies from room temperature (RT) to 400°C in air atmosphere.
Damping, i.e. internal friction, can give information about the change of internal structure, for instance, defects and cracks of matrix materials, debonding and sliding at interphase and so on[9-15].

Tungsten compound is an excellent matrix for RE ions to fabricate luminescent materials [2].
Rare earth tungstates, which introduce rare-earth metal atoms into tungsten compound, has attracted much attention because of their excellent luminescence characteristics as the fluorescent materials, phosphors, optical fibers, solid state laser material, stimulated Raman scattering (SRS) applications for their superior luminescence properties [3, 4].

“Low-carbon Technology” is the upgrade of science and technology, and scientific management shall go with the demand of low-carbon economy.
They are also high-cost industries creating pollution, especially the main targets of petrochemical engineering, chemistry, iron & steel, power, nonferrous metal and building materials.
On the one hand, low-carbon economy is closing materials cycle economy.
