Epoxies improve Aircraft skin process. (Assembly in Action).
Assembly, April, 2003
Boeing Aircraft Co. has used its unique low-cost tooling for composites (LCTC) process to build a series of eight 6- by 8-foot tools for prototyping 10 bismaleimide (BMI) exterior aircraft skins.
The project was undertaken at the Boeing Tooling Center in St. Louis. The LCTC process uses an aluminum honeycomb substructure in combination with RenPaste RP 4040 syntactic epoxy patties from RenShape Solutions, the tooling arm of Vantico Inc. Adhesive and Tooling Div. (East Lansing, MI). This provides a cost-effective rapid tooling system. The resulting models can be machined directly from computer-aided design (CAD) data and can withstand temperatures of up to 193 C for the initial supported cure of prepreg parts.
Boeing Rotorcraft and Vantico created the...
