Abstract:
1. A fuel tank, comprising: a plurality of walls composed of a first thermoset material, the plurality of walls defining a cavity; an insert material integrally formed with at least a portion of a wall of the fuel tank such that the insert material is positioned between an outer surface of the wall and an inner surface of the wall, the inner surface defining a portion of the cavity, the insert material comprises: a first layer material having a low permeation characteristic; a second layer material adjacent the first layer material having a relatively lower melting point than a melting point of the first layer material, the second layer to permanently attach a coupling apparatus to the wall of the fuel tank by melting at least a portion of the second layer material and at least a portion of the coupling apparatus; and a third layer material composed of a second thermoset material substantially similar to the first thermoset material of the walls, the third layer material being adjacent the first layer material, the third layer material defining a portion of the outer surface of the wall when the coupling apparatus is not attached to the fuel tank, wherein the first layer material is different than the second layer material, the second layer material is different than the third layer material, and the third layer material is different than the first layer material.
