The NASA Engineering and Safety Center (NESC) performed an assessment to characterize the effects of abnormal grain growth (AGG) within a metallic liner of a composite overwrapped pressure vessel (COPV). This effort focused on evaluating the mechanical response of the liner material, including the strain amplification factor (SAF), using a series of custom-designed coupons that […]

The NASA Engineering and Safety Center (NESC) conducted a technical assessment to evaluate alternatives to dichloromethane, traditionally used for bonding transparent polymeric materials. This effort was initiated in response to potential regulatory restrictions under the EPA Toxic Substances Control Act (TSCA), which could impact critical bonding processes used in spaceflight hardware and experimental systems.
