Advanced Low-Cost Composite Curing With High Energy Electron Beams. Phase 2

TL;DRAbstract

Abstract : Electron Beam (EB) curing of resin and adhesive offers significant advantages for fabricating and bonding of fiber-reinforced polymer composites for ground vehicle structural components. The EB curing process reduces the time to cross-link the polymer matrix or the adhesive compared to conventional heat curing. The process allows curing at room temperature for high throughput and reduced residual stresses for good part fit-up. EB adhesive curing also prevents de-bonding of dissimilar materials that can occur during the cool-down cycle. As part of this SBIR, Science Research Laboratory (SRL) has developed resins, adhesives and electron gun technology for high-energy electron beam curing and bonding of composites. During Phase I, SRL developed B-stageable, EB-curable resins suitable for a high for the resin transfer molding I electron beam curing process. SRL also developed a costing model for this process and applied the model to one high-quantity part. During Phase II, SRL o
