SCIGRIP’s range of methyl methacrylate (MMA) structural adhesives has been developed to tackle the challenges of bonding metals, plastics and composites. Offering a combination of strength, toughness and ease of use, MMAs are proving their worth in numerous demanding applications in the marine, transportation, and building and construction industries. This whitepaper reviews the key features of MMA adhesives and highlights their benefits over other joining technologies.
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.
Cyclone Ltd. (Karmiel, Israel), a subsidiary of Elbit Systems (Haifa, Israel), has developed an innovative composite control surface demonstrator that utilizes the advantages of composite materials and a one-shot, resin transfer molding (RTM) process in order to reduce the number of parts and steps in the assembly and production time.
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).
An invariant-based approach to reduce the number of tests required for material evaluation by Stephen W Tsai, Jose Daniel D Melo, Alan Nettles, Waruna Seneviratne and Jared Nelson.
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
