摘要

Many of the test methods for characterizing prepregs were developed in the last century andrnremain the baseline for material qualification, quality assurance, production and discrepancyrnanalysis. New test instruments and methods have created the potential for the development of arnnew baseline. The advances have occurred over a broad range of chemical and physical testsrnthat provide the opportunity for major cost savings and greater reliability of outcome. Thisrnpaper focuses on viscoelastic properties and the comparison of legacy test methods such asrnASTM D3532-12 (Standard Test Method for Gel Time of Carbon Fiber-Epoxy Prepreg) (1) andrnASTM D3531 (Standard Test Method for Resin Flow of Carbon Fiber-Epoxy Prepreg that relyrnon probing material or the weight of resin loss) with a new test method ASTM D7750- 12rn(Standard Test Method for Cure Behavior of Thermosetting Resins by Dynamic MechanicalrnProcedures using an Encapsulated Specimen Rheometer that generates quantitative viscoelasticrndata).rnWhile new test methods by themselves cannot change the specifications and therefore thernmethods of manufacturing; the recognition of the potential can help to drive the industry forwardrninto new specifications consistent with existing capabilities.
