| Abstract Scope |
Hydrogen is emerging as an alternative to fossil fuels, particularly for automobiles and airplanes. Storing hydrogen presents challenges, since its volumetric energy density is significantly lower than that of gasoline. Presently, there is currently no method for recycling thermosetting composites, and typically, at end-of-life (EOL) these materials are sent to landfills. However, by replacing the matrix with a vitrimer epoxy, constituents can be separated at EOL and H2 pressure vessels can potentially be recycled. Here we demonstrate a method to prepare vitrimer-based composites via filament winding. The vitrimer resin is formulated to exhibit suitable processing characteristics, such as viscosity and pot-life. The vitrimer material was shown to be suitable for filament winding in a manner comparable to conventional thermoset matrix composites. Future work includes mechanical testing such as short beam shear, tensile, and pressure loadings. |
