Winning Partnership Makes World Beating Ice Hockey Sticks

11 May 2009

Working closely with Huntsman, Composite Busch S.A has led the design and production of an innovative world beating one-piece hockey stick.

The stick uses a third generation toughened high-end resin system, Araldite NanoTech Composite new RTM system, to meet the most stringent demands of ice hockey players.

Players are always looking for the right combination of opposing features - flex, bend, stiffness and whip. The challenge is therefore in designing an ice hockey stick which has good stick and blade slashing properties as well as bending, resistance and torsion features. The player is not only hitting the puck directly, he is sometimes hitting the ice. The energy stored during this shock needs to be released efficiently onto the puck and this is where the one-piece “joint-less” design brings full benefits. The energy is smoothly and accurately transferred through the stick to the blade to the puck with total control from the player who always keeps close and direct contact with the puck.

Huntsman Advanced Materials has patented a new concept based on nanotechnology which significantly improves fracture resistance without affecting vital physical properties such as flexural modulus, temperature resistance and viscosity. The technology relies on the use of specific, dispersed organic nano-particles which exhibit outstanding toughening effects when incorporated in Araldite resins.

The Busch ice hockey stick is made of carbon and glass braids around a synthetic foam core which provide the stiffness needed to release maximum energy. This assembly is then inserted in a mould with an injection point at one end and an outlet point at the other end. Araldite NanoTech Composite is injected into the mould to impregnate the braids. This technology has been patented by Busch to produce the only true one-piece composite hockey stick with continuous fibre strengthening and no joints.

Members of the Swiss National Ice Hockey Team who used the “Nano IV” prototypes at the 2008 World Championships in Canada were extremely enthusiastic.
