| Résumé : |
A new carbon foam manufacturing process has been developed resulting in a low-cost, high-strength material that has been proving attractive for creation of tooling for composite parts. With the increasing number and scale of composite parts being manufactured, the reduction of cycle times and increased processing flexibility is crucial to both increasing production rates and lowering component costs. To meet these demands a composite tool can be constructed utilizing the new carbon foam material, CFOAM®, which serves as both the tool structure and heating element. The ability to heat a tool outside of an oven or autoclave provides additional flexibility as well as a reduction in capital equipment requirements and costs. Furthermore, using a self-heating tool in conjunction with autoclave processing can reduce cycle times and/or improve temperature uniformity as the tool becomes an active source of heating rather than a passive parasitic thermal mass. A CFOAM tool was constructed in which the material served as both structure and heating element. Construction techniques are discussed, and thermal imaging taken of the resulting tool during heating trials is examined. |
