Carbon Nexus Innovations in Carbon Fibre Research Sanctuary Cove 22 April 2015 Carbon Nexus Introduction & Capabilities Innovations in Carbon Fibre Research Industry Engagement & Applications Introduction & Capabilities The Carbon Nexus leadership team Derek Buckmaster, Executive Director Derek recently joined Carbon Nexus from SABIC where he was leading the technical aspects of their carbon fibre manufacturing project. Prior to joining SABIC Derek spent 19 years with GE Plastics where he worked in composites and engineering thermoplastics. With a background in technology management, strategy and product development, marketing, Six Sigma and design, Derek oversees the strategic development and marketing of Carbon Nexus. Professor Bronwyn Fox, Research Director Bronwyn leads the carbon fibre and composite research team. She has been researching more than 10 years of experience in composites research, in fields as diverse as fibre manufacture, surface treatment, 3D preforms for complex components, out‐of‐autoclave cure of composites, and structure‐property relationships. She has published more than 100 papers and has built up a team of approximately 30 researchers to establish one of the world’s leading carbon fibre composites research facilities. Steve Atkiss, General Manager Steve offers a skill base to the carbon fibre industry combining engineering and operational experience from research and development to full commercial scale carbon fibre processing. Steve has over 10 years of CF mufacturing experience with SGL Carbon Group. Key positions held during this period included Maintenance Manager, Engineering Manager, Production Manager and Commissioning Manager. Prior to joining Carbon Nexus he was the chief design expert for carbon fibre production line equipment and processing techniques with Despatch Industries. Adjunct Professor Brad Dunstan, Business Development (CEO, VCAMM) Brad’s background is a unique mix of defence, automotive industry and technology commercialisation experience.
