Carbon Nanotubes Used to Make Customizable Surfboards
June 1, 2009
PITTSBURGH - Entropy Surfboards, a division of Entropy Sports, Amroy Europe (Amroy) Ltd., and Bayer MaterialScience (BMS) LLC have teamed up to deliver a new line of custom-made surfboards that incorporate carbon nanotubes from BMS.
Entropy Surfboards believes that epoxy systems are the future of and a key ingredient in making a more durable and lively surfboard. For that reason, the company is using Hybtonite®, an advanced epoxy system from Amroy that incorporates Baytubes® carbon nanotubes from BMS, resulting in composite structures that are tougher and more durable than standard epoxy systems. The surfboards combine performance and durability with the traditional feel of a custom-shaped board. The dimensions and weight of the boards will vary depending on the specifications of each customer.
The basic construction process for surfboards has remained basically unchanged for over 50 years, making customers very particular about how their boards look and feel. The core consists of a type of foam with a stringer made of wood or plastic that spans from the nose to the tail, and is then wrapped in fiberglass. It is the final step that sets Entropy surfboards apart from traditional boards, when the Hybtonite system is used. The incorporation of BMS’ Baytubes carbon nanotubes allows Entropy to achieve increased toughness without sacrificing the flex properties of the board.
The epoxy systems used in Entropy Surfboards, as well as other Entropy Sports high-performance products and materials, are lab tested at the Berkeley Composites Lab on the campus of the University of California, Berkeley. Entropy surfboards, featuring various materials, shapes and construction methods, are also tested year round in a variety of surf conditions.
“The Bayer carbon nanotubes increase durability by a factor of two to three, while also decreasing the fatigue that is often seen in traditional boards subjected to everyday conditions,” said Rey Banatao of Entropy. “Because of the benefits they offer, we decided to pursue using carbon nanotubes in our products once they became available and affordable.”
