东丽开发出了可提高碳纤维增强树脂基复合材料(CFRP)表面平滑性的技术。采用该技术的CFRP天窗(车顶)配备在了新概念车“TEEWAVE AC1”上。新概念车所配备的天窗采用树脂传递模塑(RTM)成型。RTM法在操作时将碳纤维织物放入模具内,浸润作为母材的环氧树脂并硬化,然后从模具中倒出(脱模)做成产品。采用RTM的原有成型法在脱模后,要涂布4次涂布剂,
Toray has developed technologies that improve the surface smoothness of carbon fiber-reinforced resin-based composites (CFRP). CFRP skylights (roofs) using this technology are available on the new concept car “TEEWAVE AC1”. The new concept car equipped with skylights using resin transfer molding (RTM) molding. RTM method in the operation of the carbon fiber fabric into the mold, infiltration as the parent material of epoxy resin and hardened, and then poured from the mold (mold) made of products. RTM using the original molding method after demolding, to be coated 4 times coating agent,
