Chopped Carbon fiber is made of sized or non-sized carbon fiber by chopping them to short fibers. The short fiber dispersed more evenly compared with fiber filament. So it is usually applied to carbon fiber reinforced plastics.
Chopped carbon fiber can be mainly used as follows:
(1) Reinforce the modified plastics such as nylon (PA), polypropylene (PP), polycarbonate (PC), phenolic (PF), polytetrafluoroethylene (PTFE), polyimide ( PI), etc.;
(2) Construction: reinforce the materials like cement, conductive coatings paint;
(3) Electric field: can be used to produce conductive paper, electric panels, conductive FRP, needle mat, etc.
