Carbon Fiber customers have developed wide varieties of usage of the fibers making best use of the fibers' favorable properties as presented below. Another favorable point is that JCMA member companies are able to offer wide range of assortments of fiber performances as attained by using different raw materials and by applying different processes under different processing conditions.
| Types | Specifications | Major Usage |
| Fillament | A yarn constituted of numerous number of fiber: twisted, untwisted, twisted-and-untwisted | Resin reinforcement material for CFRP, CFRTP or C/C composites, having such usage as Aircraft/Aerospace equipment, sporting goods and industrial equipment parts |
| Tow | An untwisted bundle of yarn constituted of extremely numerous number of fiber | Ditto |
|
|
A yarn made of spinning of staples | Heat Insulator, Anti-friction material, C/C composite parts |
| Woven fabric | A woven sheet made of filament or staple yarn | Resin reinforcement material for CFRP, CFRTP or C/C composites, having such usage as Aircraft/Aerospace equipment, sporting goods and industrial equipment parts |
| Braid | A braided yarn made of filament or tow | Resin reinforcement material particularly suitable for reinforcement of tubular products |
| Chopped fiber | A chopped fiber made of sized or non-sized fiber | Compounded into plastics/resins or portland cement to improve mechanical performances, abrasion characteristic, electric conductivity and heat resistance |
| Milled | Powder made by milling fiber in a ball-mill etc. | Compounded into plastics/resins or rubber to improve mechanical performances, abrasion characteristic, electric conductivity and heat resistance |
|
|
A felt or mat made by layering up of staple by carding etc. then needle-punched or strengthened by organic binders | Heat insulator, base material for molded heat insulator, protective layer for heat resistance and base material for corrosion-resisting filter |
| Paper | A paper made from staple by dry or wet paper-making | Anti-electrostatics sheets, electrodes, speaker-cone and heating plate |
| Prepreg | An intermediate material in a form of half-hardened sheets made of Carbon Fibers impregnated with thermo-setting resin, qualities of which being stable and sustained long enough and therefore easily applicable for automatic sheet-layering | Aircraft/Aerospace equipment, sporting goods and industrial equipment parts needing lightness in weight and high performances |
| Compounds | A material for injection moulding etc. made of mixture of thermo-plastics or thermo-setting resins added by various additives and chopped fiber and then being compounded | Housing etc. of OA equipment taking advantages of electric conductivity, rigidity and lightness in weight |
