Vette, the magazine focusing on, what else, Corvettes, has a comprehensive history of the body materials used throughout the beloved sports car’s history. From fiberglass to carbon fiber, Vette has a great historical record. The best part is, it’s all available online.
Here’s an excerpt, but make sure to click through to read the rest. Even if you don’t have a Corvette or aren’t particularly a car nut, it’s a great history of material engineering.
Fiberglass was first considered for use on a GM vehicle by legendary designer Harley Earl. Besides a certain “exoticness” for the early ’50s and the undeniable weight advantage, fiberglass offered an economical way to create the low-volume Corvette without investing in expensive sheetmetal-stamping dies.
GM’s Parts Fabrication Operation was tasked with figuring out the intricate requirements for the ‘53 Corvette’s body, while supplier Molded Fiber Glass Company (with some support from Owens Corning Fiberglass) got the contract to build them. Amazingly, the company was awarded the business in April 1953 and was asked to deliver the bodies by the June 1953 start-of-production deadline—and they had never built a car body previously.Not surprisingly, there were plenty of unknowns when it came to designing and building those first Corvettes. Tests had to be done to determine how many layers of fiberglass were needed for the various areas of body, as well as the interior “tub.” And for products so large, the correct ratio of resin and plastic hardener had to be determined, not to mention figuring out how long it would take for each hand-laid body to cure. Also, it wasn’t clear at first how many separate parts would be required to construct each body, and a surface finish suitable for production-quality paint was far from assured.
