Carbon foam tooling system development finalised.(MANUFACTURING)
Advanced Composites Bulletin, June, 2009
After nearly two years of research and development, the processing and performance requirements of a carbon foam tooling system, which was developed by ACG, UK, in conjugation with GrafTech International Ltd, based in Parma, Ohio, USA, has now been fully characterized. The technology will be used for concepts in coefficient of thermal expansion (CTE), low mass composite tooling areas.
The tooling system, called ACG Grafoam FPA-20, not only exhibits a low CTE (2.3 x [10.sup.-6].[degrees][C.sup.-1]), but it also has a thermal resistance that exceeds composite processing requirements, according to ACG. This high thermal resistance offers significant advantages and cost savings when manufacturing high-temperature tooling. With no requirement for a master model,...
