Awards Finalists Australian Composites Pty Ltd − Australia Name of Product or Process: Rapid sun-light UV-curable prepregs Partners: LM GlasFibre (Denmark) and Cooperative Research Centre for Advanced Composite Structures Limited. Recycled Carbon Fibre Limited - United Kingdom Name of Product or Process: Continuous pyrolysis process for the recovery of carbon fibre from carbonfibre-reinforced composites Partner: the Boeing company. Studio Noach United Kingdom Name of Product or Process: A ‘green floating' house. A full concept for living on water on a foundation of recycled waste (Polystyreen/RexwallTM). Winner “Building & Construction” >> FRPM Pipes for sewage system Kurimoto Ltd (Japan) Partner: National Institute for Rural Engineering (Japan) The FRP layer consists of high-strength glass fibres wound in the circumferential and axial directions by the filament winding process and hardened by thermosetting unsaturated polyester resin. The included resin mortar is a polyester concrete made from selected fine sand hardened by unsaturated polyester resin, having a compressive strength several times as high as an ordinary cement concrete. The interior and exterior FRP layers bear the bending stress of pipes, while the middle resin mortar layer keeps each FRP layer at a certain interval and transmits shearing force. Dynamically, this structure is ideal, in particular excelling in strength against external pressures such as soil and truck load, and against as various internal pressures as well. FRPM pipes have such excellent corrosion resistance properties that they can serve as sewage pipes for a long time, whereas concrete sewage pipes are corroded by the highly acid environment in sewage systems. FRPM pipes have such excellent earthquake-proof properties that they do not crack even in case of strong earthquake. These flexible pipes can adjust to ground displacement, due to the flexibility and elasticity of joints. The strength of FRPM pipes is great enough to protect them from internal and external pressure. As they are flexible, the stress occurring in the ground is lower than those of non-flexible pipes. Therefore, they don’t require any special foundation, regardless of ground depth, deep or shallow. Superior dimensional precision at joints and an original rubber ring design guarantee outstanding water-tightness, with no risk of leakage or external injuries. FRPM pipes are substituted for steel pipes and concrete pipes to reduce costs and to prolong the system’s service life. The applications of FRPM pipes are the following: sewage, jacking pipes, water for irrigation, tube well casing & screen, protection for power & communication cables. Kurimoto Plastics Co., Ltd has developed rehabilitation methods for overage pipelines or tunnels through a joint research project with the National Institute for Rural Engineering. One is the SIL method using thin-walled FRPM pipes to rehabilitate over-aged pipelines. Another is the horseshoe-type pipe-in-tunnel construction method to rehabilitate over-aged tunnels. These methods allow fast rehabilitation while reducing costs. Finalists Mahindra Composites − India Name of Product or Process: Bamboo composite pole Partner: Internal teams to develop the winding machine, end castings, connectors and applications.
