Sophisticated control systems or process monitors can be installed on most ovens and autoclaves used to cure composite materials. A modern system combines control, monitoring, and documentation in a single unit. The result is greater process automation, improved quality and batch-to-batch consistency, and permanent and unalterable storage of process records to meet the most stringent requirements for demanding applications. This paper describes the benefits of upgrading to a new control system or process monitor and provides guidelines for choosing the best system.
This white paper, by Steve Zeller of Southbrook Technologies Inc. (Alpharetta, Ga.) addresses some of the technical and physical design parameters to be considered when designing a robust autoclave system for the curing of composite parts and structures.
This paper, presented in May 2010 at SAMPE 2010 in Seattle, is titled, "Application of abrasive-fluidjets for precision machining of Composites." Authors are H.-T. Liu, E. Schubert, D. McNiel, and K. Soo from waterjet machinery manufacturer OMAX Corp. (Kent, Wash., USA).

Numerical Algorithms Group (NAG) offers “The Benefits of Using Rigorously Tested Routines from Numerical Libraries—Composites Engineering Edition.” It provides a framework for
understanding how commercially available numerical libraries can be a powerful tool to manage today’s composites engineering studies, including discussion of: commercially available numerical libraries vs. numerical code developed in-house; commercially available numerical libraries vs. open source code; quality control– validation and testing issues; future-proofing costs of migrating to newer computational platforms such as GPU or HPC environments; future proofing—the value of library documentation vis-à-vis an application’s entire lifecycle and the given of staff turnover; tips on real-world trials to determine ability of numerical libraries to speed application development
