Reinforcement materials will provides strength and rigidity to the composite and also helping to support structural load.
Apparatus and procedure Materials.
Impact test is a method for determining behavior of materials when subjected to shock loading in bending, tension or torsion [6].
After 30 days’ in seawater, white particles oozed from the specimens, this might be attributed to the extraction of soluble materials [7].

At present, more researches have been done on the change of materials than the surface structure to improve the brake disc performance.
Set the materials of the brake disc and friction plates, as brake disc is HT200, friction plates are resin with reinforced composite materials.

Study on Processing Properties of Epoxy Resin System in VARI Chenhui Zhao, Guangcheng Zhang, Weimin Sun and Aihua Shi Department of Applied Chemistry, School of Natural and Applied Science, Northwestern Polytechnical University, Xi’an,710129,P.R.China zhaohui18201@163.net, zhangguc@nwpu.edu.cn, outcast191@163.com and Shiaihua2000@126.com.
As a low cost moulding technology, VARI is widely used to produce advanced composite materials.
The resin is injected through either a single or multiple inlet ports (depending on the part size and shape),then transferred into the preform by a pressure gradient (induced by the vacuum pressure), and gravity and capillary effects; (c) curing of the impregnated perform[5,6].Because VARI process is usually used to produce the large-scale composite structures such as ships, refrigerated containers and bridge deck[7], a large amount usage of raw material usage, complex and time-consuming process make it necessary to study in-depth on resin used in VARI.
