DUNA-USA Inc. (Baytown, Texas) is debuting its BLACK CORINTHO HT 800 high- temperature tooling board, which offers low coefficient of thermal expansion (CTE) at temperatures up to 400°F, coupled with high thermal conductivity for reducing oven and autoclave cycle times.
In addition to standard and high-temperature tooling boards, DUNA-USA also is showcasing its high-temperature sealers and adhesives. DUNA-USA also says that BLACK CORINTHO HT 800 offers excellent machinability and easier handling than traditional metal tooling, making it a cost-effective alternative for low-volume prototypes and composite layup tools. DUNA-USA also manufactures the CORAFOAM line of polyurethane tooling boards, with densities from 4-31 lb/ft3. Known for its ultrasmooth surface and ability to produce chips instead of dust, CORAFOAM applications include composite layup tooling, vacuum forming, prototyping, and CAD verification tools.
BMW AG's Dingolfing, Germany, auto manufacturing facility is well known for churning out a variety of car models and types, and the 7 Series is among them, famous for its steel/aluminum/composites construction. Does this car represent the optimum of composites use in vehiicles? This plant tour of the Dingolfing plant looks at how composites on the 7 Series come together.
ATL and AFP-based preforming options now abound for processing dry and/or impregnated reinforcements as quickly as 1 minute or less with potential yearly part yields in the millions.
Compared to legacy materials like steel, aluminum, iron and titanium, composites are still coming of age, and only just now are being better understood by design and manufacturing engineers. However, composites’ physical properties — combined with unbeatable light weight — make them undeniably attractive.
