Komatsu Refining Co., Ltd. and Fanuc Corporation have developed a technology for making high-strength carbon fiber reinforced plastics (CFRP) products using an injection molding machine having a carbon fiber length of 5 mm and a content of 35%, which is smaller than that of the conventional product Long, high content.
The injection molding products expected to put on the market, the company consolidated sales revenue from the current about 38 billion yen to about 50 billion yen, of which the carbon fiber business will reach 5 billion yen.
The project is jointly completed by both parties, of which Komatsu refining responsible for material design, Fanuc responsible for injection molding technology.
The molded product made of Komatsu's uniquely developed thermoplastic CFRP material 'CABKOMA KB chip' has a tensile strength of 150 N / mm 2, a flexural strength of 260 N / mm 2, and a bending strength of about 3 times that of polycarbonate. For intensity than the current level increased by 50%.
Komatsu Refinery is developing a carbon fiber building materials application market and has successfully developed and successfully manufactured CFRP screws, joint plates, etc. Aiming at the seismic strengthening of building materials, preventing the corrosion of metal screws and nails and the wood deterioration due to condensation.
At the same time, Komatsu Refinery is using its advantages of fiber textile manufacturing technology to expand its carbon fiber business, and earthquake-resistant reinforcing ropes and elevating fences have been put into practical use and anchor plate projects to prevent landslide hazards are also underway.
