When developing a new composite component, one of the most important early decisions is selecting the right curing process. Autoclave and out-of-autoclave (OOA) methods both deliver high-performance parts, but each offers distinct advantages depending on design requirements, production volume, and cost targets.

Autoclave processing remains the gold standard for aerospace-grade parts because it offers maximum consolidation, minimal void content, and excellent mechanical performance. The elevated heat and pressure produce highly consistent laminates with exceptional strength-to-weight ratios. It’s ideal for complex geometries, structural components, and applications that demand the highest reliability.

Out-of-autoclave processing, by contrast, can achieve impressive mechanical performance without the need for a pressure vessel. Utilizing vacuum bagging, controlled oven curing, and specialized materials, OOA is efficient, flexible, and well-suited for medium-to-high production volumes. It also reduces cycle times and operational costs, making it an attractive option for many OEM programs.

The choice between autoclave and OOA depends on the part’s engineering requirements, tolerances, and production scale. An experienced composite manufacturer can guide OEMs through this decision, ensuring the selected process delivers optimal performance and long-term repeatability.
