Fender protective structures
First Claim
1. In a fender system for inside the hull of a ship comprising an elongated longitudinally extending fender, said fender having a first layer of ultra-high molecular weight material, a second resilient layer bonded to said first layer, said second layer having a plurality of openings in laterally spaced and longitudinally spaced relationship, a third layer of rigid non-resilient material bonded to said second layer, said third layer having a plurality of openings in laterally and longitudinally spaced alignment with said openings in said second layer, vent holes in said fender that communicate said aligned openings with the interior of said hull for venting fluids, and means for attaching said third layer to said hull of said ship.

Abstract
An impact pad for use in absorbing impact forces wherein the pad is composed of a first outer layer of an ultra-high molecular weight material, an intermediate layer of elastomeric material bonded to the first layer, a third or base layer of ultra-high molecular weight material wherein the base and the elastomeric layers have a plurality of laterally and longitudinally spaced bores to provide the resiliency to the impact forces on the outer layer.

- 8. An impact pad for use in absorbing impacts comprising a composite pad with an outer layer of rigid non-resilient low-friction material, said outer layer having an outer surface and an inner surface, said pad having a second intermediate layer of elastomeric material bonded to said inner surface of said outer adjacent layer, a rigid base layer bonded to said intermediate elastomeric layer said elastomeric layer and said base layer having coextensive apertures extending through said base layer and substantially through said elastomeric layer to provide a resiliency to an impact force on said outer layer, wherein each of said coextensive apertures define a chamber, and narrow vent bores in said composite pad communicates said chambers through said pad to the exterior of said outer surface of said outer layer.

13. An impact fender system for use in absorbing shocks and impact forces comprising a plurality of longitudinally extending impact fenders in laterally spaced rows, each of said fenders having a plurality of pads in horizontal alignment, each pad having an outer layer of ultra-high molecular weight material, each of said pads having a second intermediate layer of elastomeric material bonded to one of the surfaces of said outer layer, each of said outer layers having the other surfaces facing exterior of said pad, a base layer bonded to each of said elastomeric layers, each of said elastomeric layers and said base layer in adjacent abutting relationship having coextensive apertures extending through said base layer and into said elastomeric layer to define a plurality of chambers which facilitates the compression and bulging of said elastomeric layer on said fender receiving an impoact force, and vent holes extending through each of said fenders communicating said chambers exteriorly of and through said other surface of said pads.
