Résumé : |
A new carbon foam system has been developed that results in a low-cost, high-strength material that has been proving attractive for creation of tooling for composite parts. Composites are stronger, lighter, and less subject to corrosion and fatigue than materials that currently used for fabrication of advanced structures. Tools to manufacture these composite parts must be rigid, durable and able to offer a coefficient of thermal expansion (CTE) closely matching that of the composites. Current technology makes it difficult to match the CTE of a composite part in the curing cycle with anything other than a carbon composite or a nickel iron alloy such as invar.
Fabrication of metallic tooling requires many expensive stages of long duration with a large infrastructure investment. Carbon fiber reinforced polymer resin composite tooling has a shorter lead-time but limited production use because of its low cost, light weight, machinability, vacuum integrity, and compatibility with a wide range of curing processes. Large-scale tooling case studies will be presented detailing carbon foam's potential for tooling applications. |
