| Résumé : |
Autoclave technology is widely used by Tier 1 and Tier 1 suppliers to manufacture aerostructures for leadint aircraft manufacturers. This technology allows the production of very high-quality lightweight parts because, if the procedure is carried out properly, the autoclave pressure exerts on the carbon fibre laminate a force capable of highly compressing the trapped air and the volatile gases that would otherwise form gaps in the cured resin and thus be problematic in a finished composite part. However, a high specialization is often required to achieve these results in addition to the high cost the process involves, mainly due to the long cycle times and high energy consumption. |
