Study on preparation of SiO2/epoxy resin hybrid materials by means of sol-gel [J].

Thus, its use has been expanded gradually over time in many industrial areas such as aerospace, automotive, construction materials and sports goods.
But the application is only for low value waste such as filler, reinforcement, or construction materials.
Nitric acid solutions can decompose carbon fiber in the composite materials.
For this reason, they can dissolve organic materials.
The epoxy resin materials are manufactured by condensation polymerization, releasing small molecules such as water and alcohol.

The Effects of Fiber Volume Fraction on the Vibration Damping Characteristics of Three-layer-connected Biaxial Weft Knitted Fabric Reinforced Composite Materials Jingxue Liu1,a, Jialu Li1,b 1 Composites Research Institute of Tianjin Polytechnic University & Tianjin and Education Ministry Key Laboratory of Advanced Textile Composite Materials, Tianjin 300160, China aliujingxue1031@sina.com, bfhcls@tjpu.edu.cn Keywords: three-layer-connected biaxial weft knitted fabric (TBWK), damping, composite materials, vibration test.
Mostly, soft yarn with finer yarn count (5 ~ 50tex), high fracture strength and high shear strength, is used as knitting yarn, such as polyester, Kevlar and other materials.
Materials The materials considered in the analysis are constituted of carbon fibers in an epoxy matrix and were fabricated to TBWK fabrics: The first inserted layer of the TBWK fabric is weft yarns, the middle inserted layer is warp yarns and the last inserted layer is weft yarns.
