　Carbon Fiber Reinforced Plastic (CFRP) is said to be at the cutting edge in automotive weight reduction technology. Its use was limited to small-lot production vehicles but in recent years utilization has seen gradually increasing in Europe. The following report summarizes exhibits and lectures at workshops during the JSAE Exposition 2016 held in Yokohama. The latest developments in CFRP technology will also be introduced.

　Various CFRP molding methods have been developed and are still evolving. Among them, resin transfer molding (RTM) is finding increasing use in the automotive industry, and the molding processes of HP-RTM (High Pressure RTM), compression RTM, and wet-RTM will be analyzed as representative examples, along with the products they are used to make. Also CFRP-metal composite, in which CFRP is integrated with metals such as steel or aluminum, will be introduced. The tailored rolled blank B-pillar reinforced with a CFRP stiffener that was developed by Mubea Carbo Tech, and a new composite material called KRAIBON developed by KRAIBURG, will also be examined.
