While autoclave cure is the established standard for effective consolidation and cure of composite parts and structures, especially for aerospace manufacturers, out-of-autoclave (OOA) processes have been steadily evolving and becoming more prevalent as fabricators seek ways to reduce composites manufacturing cycle time. In fact, it is possible now to achieve autoclave properties — e.g., <1% porosity — out of the autoclave. And as fabrication migrates out of the autoclave, several benefits follow: Elimination of autoclave capex investment, elimination of freezers for prepreg storage, reduced energy consumption and shorter cycle times. Ultimately, the OOA process validates the use of composites for an expanded spectrum of applications.

Within this sphere, composites curing ovens have followed OOA’s evolutionary path, with more flexible systems and more accurate, higher-end controls to further improve part quality. Composites curing ovens now possess a range of footprint dimensions, temperature ranges, heat sources, specialization, and, depending on the supplier, are completely customizable in an attempt to fit the needs of specific process requirements. This is the fourth in a series of Tech Tables that CW has published, each designed to provide as comprehensive a list as possible of suppliers, their products and selected product specifications.

This table of composites curing ovens has been built with data provided by suppliers, and is intended to provide a representation of the products they offer. While CW was unable to receive data from all composite curing oven suppliers, prominent companies unlisted — but which should be distinguished in this area — include Taricco Corp.JPW Industrial Ovens & Furnaces and ASC Process Systems
