Awards Winner “Aerospace” >> Composite applications for radio telescopes (CART) project design, the innovation has huge applicability. Several applications in the wind energy, ship, spacecraft and aircraft industries have been identified. For example, based on the first Partner: Profile Composites Inc. (Canada) analytical estimations, local hybridization is Mechanical fastening techniques are considered to be incompatible considered to offer a weight reduction of about 500 kg per intersegment joint for a full with the physics of fibre-reinforced plastics, as such fastening composite Ariane 5 booster, which results in techniques cut the bearing fibres at the bolt hole and induce high stress concentrations . The local hybridization technique is suitable considerable structural weight saving with the corresponding payload efficiency, and cost savings, considering that 1 kg costs for every application involving highly loaded composite bolted €25,000 in spacecraft applications. joints.

Winner “Sports & Leisure” >> One-piece “jointless” composite ice hockey Composites Busch SA (Switzerland) Partners: Huntsman (China) and EPFL (Switzerland) Ice-hockey players are always looking for the right combination of opposing features – flex, band, stiffness and whip. The challenge is designing an ice-hockey stick that has good stick and blade slashing properties, as well as bending 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 “jointless” design brings full benefits. The energy is smoothly and accurately transferred through the stick to the blade and then to the puck with total control from the player, who always keeps close and direct contact with the puck. Huntsman Advanced Materials provided the easy-to-process Araldite® NanoTech composite RTM system, blended with organic nanoparticles that exhibit outstanding toughening effects. EPFL independently quantified and validated the properties (toughness and resistance to impact and vibration). This only one-piece “jointless” composite ice hockey combines good stick and blade slashing properties, as well as bending and torsion features. The one-piece design allows the energy stored during the shock on the ice to be released efficiently onto the puck. It has better solidity and durability, and a longer lifetime. Fewer vibrations are transmitted to the body and therefore reduced associated injuries. Today, Busch is producing 5,500 hockey sticks a year (mainly custom sticks). The goal is to increase production by 25% to reach 7,000 sticks.
