Abstract
A tank and methods for manufacturing the tank are provided. In one aspect, the tank includes a cylindrical wall formed into a shape that matches a cylindrical mandrel. The cylindrical wall can include a neat resin layer having a plurality of consolidated neat resin films, and a thermoplastic composite material layer having a plurality of consolidated fiber-reinforced composite tape layers. At least one fiber-reinforced composite tape layer of the thermoplastic composite material layer can be consolidated with at least one neat resin film of the neat resin layer.
