Teho Tenax, the core company of the Teijin Group's carbon fiber and composites business, announced that it has developed a new high tensile strength, high impact prepreg that combines the carbon fibers developed by Toho Tenax for aviation applications and Dedicated carbon nanotubes (abbreviated as 'CNT').
Currently, Toho Tenax's new hybrid prepreg has been adopted by Mizuno Corporation to create a new golf club that weighs nearly 30% less weight than conventional components of the same thickness.
When the ball is struck, this high tensile prepreg allows the club to bend properly, reducing the impact by more than 10% to reduce club movement in the next swing.
The surface of the carbon nanotubes (CNTs) has been specially treated, and the structural elements of the carbon nanotubes (CNT) have been uniformly dispersed when the carbon fibers (CNTs) containing the matrix resin impregnate the carbon fibers of Toho Tenax.
The hybrid combination of carbon fiber and carbon nanotubes (CNT) achieves a high-quality carbon fiber composite (CFRP). This carbon fiber composite material provides higher tensile strength and impact resistance, and is also very durable. This is because the carbon nanotubes (CNTs) are uniformly dispersed, so that the carbon fibers and the matrix resin do not peel off from each other.
Teijin Group is accelerating its new high-strength, high-impact prepreg materials for high-end applications such as sports, leisure and aviation. In these applications, weight reduction and high functionality are very important.
Teijin Group is also integrating upstream and downstream to strengthen its ability to provide solutions for diversified global businesses.
Since CFRP is used in a range of areas from aerospace and automotive to infrastructure and leisure, its specified performance must vary greatly depending on the application.
To meet these special requirements, Teijin is developing technologies for the diversified combination of carbon fibers and matrix resins and for special processing needs because when the formed CFRP products are subjected to a strong impact, carbon fiber sheets are Matrix resins tend to peel off from each other, resulting in decreased strength and strain.
Therefore, people have been looking for technologies that can better combine carbon fibers with carbon nanotubes (CNTs), but until now, the cohesiveness of carbon nanotubes (CNTs) makes them unable to be uniformly dispersed in the matrix resin, resulting in Prepreg quality is unstable.
