Organic, High Temperature Resin for Lightweight Gun Barrels

CRG proposes to reduce the weight of gun barrels, including tank, howitzer, and mortar tubes, with its proprietary MG resin systems and composites. MG composites represent a new class of light weight, low-cost, easy-to-process high-temperature structural materials. They enable the use of light weight composites in gun barrels, reducing weight and cost, while enhancing lifespan and robustness. MG resin is low-viscosity at relatively low processing temperatures and compatible with a variety of reinforcements, enabling multiple manufacturing processes. CRG has previously demonstrated the high temperature capability of the materials, as well as the ability to filament wind over a metal mandrel in combination with IM7 carbon tow. Resin batch production has been scaled to 20 kg (45 lbs) batches, with clear routes forward for further scale up.
