旭化成，推出碳纤维增强尼龙UD带与再生碳纤维屏蔽材料

Core Insights - Asahi Kasei has showcased two significant innovations in carbon fiber: carbon fiber reinforced polyamide UD tape and electromagnetic wave shielding material made from recycled carbon fiber (rCF) [1] Group 1: Carbon Fiber Innovations - The carbon fiber reinforced polyamide UD tape is a sheet material made by aligning carbon fibers in one direction and impregnating them with polyamide resin, resulting in high strength in specific directions. This material can be customized for different directional strengths by altering the layering angle and molding [1] - The UD tape has applications ranging from foldable smartphones to electric vehicle (EV) drive systems. For instance, using this tape to reinforce the resin electric motor casing of an EV reduced the weight from approximately 50 kg for a metal casing to just 5 kg, achieving a weight reduction of 90% [1] Group 2: Recycled Carbon Fiber Material - The rCF non-woven fabric is made from a blend of recycled carbon fiber and nylon fiber, offering excellent flexibility and comparable shielding performance to metal materials, achieving over 40 dB shielding effectiveness at frequencies above 100 MHz [1] - This material can reduce the weight of inverter housings by about 50% compared to traditional aluminum castings and supports secondary processing like drilling, making it suitable for automotive parts, drones, aerospace, and electronic devices [1]
