Abstract

Validation of the RAVEN cure kinetic model is presented for the CYCOM 5320-1, FM309-1, and FM300-2 epoxy resin systems. Validation is performed through comparison of predicted results to physical test results by DSC, TMA, and DMA. Further, mechanical testing is performed at varying degrees of cure and determined that potential reductions in the specification minimum cure requirements are justified. Additionally, a scalable mechanical strength table was developed to provide knockdown factors for under-cured parts.Implementation methodologies are introduced to validate the RAVEN cure kinetic model and to determine the true minimum degree of cure. These methodologies adhere to standards adopted by the Aerospace Industry. Enhancements are made to the kinetic model software to promote the adoption of large-scale composite bonded structure, including features providing visual cure status, calculation of additional time at temperature required to meet a minimum degree of cure, and determination of whether pressure is needed during a re-cure.
