As the demand for carbon fibers in hydrogen storage infrastructure increases, sustainable recycling of Composite Overwrapped Pressure Vessels (COPVs) becomes increasingly important. This study implements a low-temperature, low-pressure autoclave-based chemical process that efficiently recovers continuous from pristine carbon-epoxy COPVs without requiring disassembly or destructive sectioning. Remarkably, this method preserved 99% fibers. However, reclaimed exhibit slight reduction tensile...
Abstract Aircraft crashes often initiate or accompany fire incidents. Post‐crash fires, in particular, can mask destroy critical fractographic failure features necessary for accident reconstruction. As a first step developing coherent strategy composite aircraft post‐crash forensic analysis, series of vertical flame tests were performed on mechanically failed Cytec T40‐800/Cycom® 5215 graphite/epoxy unnotched compression, short beam strength, and in‐plane shear specimens. Visual inspection...
Fire damage involving mechanically failed composite aircraft structures can dramatically alter their exposed surface characteristics in ways that inhibit fire forensic analyses. In this work, the effects of exposure on Cytec T40- 800/Cycom® 5215 graphite/epoxy composites were examined. Coupon level vertical tests performed unnotched compression and in-plane shear specimens. The was characterized by visual inspection scanning electron microscopy. development specimens involved a concurrent...
In-flight lightning strike damage to aircraft composite structures may compromise airworthiness. Hence, it is crucial incorporate adequate protection systems mitigate the current. Most (LSP) techniques involve bonding a metallic conductive layer cured laminate exterior. In this study, novel LSP integration technique was used develop unitized panels with three different layers: pitch carbon fiber paper (PCFP), graphene (GP), and copper mesh (CM). Each overlaid on through-the-thickness...
