Abstract
Differentially armored, vehicle fuel tank structure possessing contiguous, united and integrated, tank-wall regions including a high-puncture-risk region formed of lightweight, penetrable, non-armoring material, and joined thereto, a low-puncture-risk region formed of hardened and heavyweight, anti-penetration, armoring material. Included also is a sprayed-on, allover, tank-exterior, self-sealing, anti-fuel-leak barrier coating formed principally of a high-elastomeric material which reacts in a material-swelling manner on contact with fuel in the tank structure.
Claims4
Differentially-armored, altered-armoring-priority, liquid fuel tank structure for a vehicle comprising
- a liquid fuel tank having a defining tank wall possessing an outside surface, and both a high-puncture-risk, entry-wound zone, and a low-puncture-risk, exit-wound zone, and in association respectively with said zones, integrated, functionally differentiated, tank-wall regions joined to one another, and including, for said entry-wound zone, a region formed of lightweight, non-armoring material, and for said exit-wound zone, a region formed of heavyweight, armoring material, and
- distributed over the entirety of said outside surface, a self-sealing, anti-puncture-wound-leak, barrier coating formed throughout with a high-elastomeric material which reacts in elastomeric and material-swelling self-sealing manners on contact with leakage fuel coming from said tank.
A method for creating a differentially-armored, altered-armoring-priority, vehicle liquid-fuel tank structure possessing a tank with a wall having an outside surface, and characterized by contiguous, united and integrated, functionally differentiated, a high-puncture-risk, entry-wound and a low-puncture-risk, exit-wound zones, said method comprising
- forming for the entry-wound zone a tank-wall region utilizing lightweight, non-armoring material,
- forming for the exit-wound zone, in joinder with the first-mentioned formed tank-wall region, another tank-wall region utilizing heavyweight, anti-penetration, armoring material, and
- jacketing the tank-wall's outside surface with a self-sealing, anti-puncture-wound-leak, barrier coating formed throughout with a high-elastomeric material which reacts in both elastomeric and material-swelling self-sealing manners on contact with leakage fuel coming from the tank.
