摘要: The co-curing process for advanced grid-stiffened (AGS) composite structure is a promising manufacturing process, which could reduce the cost, augment advantages and improve performance of AGS structure. An improved method named soft-mold aided replaces expansion molds by whole rubber mold adopted in this paper. This capable to co-cure typical with manufacturer’s recommended cure cycle (MRCC). Numerical models are developed evaluate variation temperature degree during process. simulation results were validated experimental obtained from embedded sensors. Based on modeling framework, can be optimized reducing more than half time MRCC while obtaining reliable cure. shape size effects distrib...
