C/C composite

C/C composite is a carbon-carbon composite material reinforced by high strength carbon fiber for the purpose of improving strength and shock resistance of carbon materials。 It is a hi-tech carbon material that is equally selected for general industrial use as it is used in advanced technological fields such as aerospace and semiconductor manufacture。 To meet the diversified needs of the 21st century, the Toyo Tanso Group offers a filament winding type in our FW Series, a two-dimensional type in our CX Series and special grade composites。
