MATERIALS TECHNOLOGY

1. Existing materials technology:
A. Fiber types

Fiber types	Specification	Performance
Carbon fiber	PAN-based carbon fiber IM carbon fiber UM carbon fiber	Ÿ high strength Ÿ light Ÿ high elastic modulus Ÿ high fatigue strength
Fiberglass	E-fiberglass	Ÿ high temperature resistance Ÿ high resistance to corrosion Ÿ high strength Ÿ small extension
Carat fiber		Ÿ ultra-high strength Ÿ high elastic modulus Ÿ excellent acid resistance and alkali resistance

B. Resin types: epoxy
C. Weaving materials: braided, 3K weaving carbon cloth
As the three-dimensional weaving material, braided mainly makes three-dimensional fiber bundles distributed symmetrically in the inner wall of hollow pipe to support it and strengthen the stability and rigidity of the structure.

2. New technology
We cooperated with the College of Materials of Xiamen University on the project “Industrial Development of Rackets with High performance Based on Nanocomposite”, which is to deeply develop the technology of organic/inorganic hybrid nanocomposite and apply it to the sports goods so as to greatly upgrade the technology of materials of sports goods.

3. Main materials of products
Carbon fiber (hot-melt weaving board): Our Company has the technology of hot-melt weaving board which is put into production at a large scale.
