Using opening carbon fiber bundle technology makes it easier for thermoplastic resin to penetrate the fibers. Additionally, creating woven fabrics from the opened fibers eliminates fiber crimping and allows the elastic modulus of the carbon fibers to be expressed. Polyamide 6 was chosen as the thermoplastic resin for automotive and industrial applications. The resulting CFRTP had 1.5 times higher tensile strength than general-purpose woven fabrics. Failure was primarily due to carbon fiber breakage rather than resin-to-fiber interface exfoliation. Thin-layer woven fabrics can be easily stacked at 0°/90° and fabricated into complex shapes.

摘要

Using opening carbon fiber bundle technology makes it easier for thermoplastic resin to penetrate the fibers. Additionally, creating woven fabrics from the opened fibers eliminates fiber crimping and allows the elastic modulus of the carbon fibers to be expressed. Polyamide 6 was chosen as the thermoplastic resin for automotive and industrial applications. The resulting CFRTP had 1.5 times higher tensile strength than general-purpose woven fabrics. Failure was primarily due to carbon fiber breakage rather than resin-to-fiber interface exfoliation. Thin-layer woven fabrics can be easily stacked at 0°/90° and fabricated into complex shapes.
