Recycling and Application Technology of the Fiber Reinforced Composite
■ Technology Overview
Carbon fiber reinforced composite (CFRP) has great potential to replace the use of metals. Airbus and Boeing Co. announced that the recycling rate of CFRP will increase by 70% to 90%. Also, it will be an
issue for the evolution of the light weight body of the vehicles in the future because the European Union sets regulations to stipulate the recycling shares and reuse of automobiles. This project used the chemical degradation method with the environmental friendly catalyst and the microwave pyrolysis technique by utilizing the microwave absorption characteristics of carbon fiber to design a high-efficiency fiber composite material recycling system. The process is fast, energy saving and the CFRP recycling rate exceeds 95%.

Carbon Nanotube Modified Vibration Damping Carbon Fiber Composites
■ Technology Overview
The damping effect from the micro-slip between the wall layers of the carbon nanotubes is used to suppress the vibration and greatly reduce the attenuation time during the robotic arm operation. This technique can be widely used in various vibration suppression and high payload robot components. This technology has been imported into the prototypes of Delta robot, six-axis multi-joint lightweight robot arm, and heavy-duty robotic arm, all of which have completed the α-Test verification.
■ Features
• Carbon nanotube amine-based modification technique, reducing liquid waste by 80% and cost down by 85%
• The vibration attenuation time of the robotic arm is reduced by 50~60%
• 2021 ITRI Outstanding Research Award
