    摘要: A method of manufacturing a fiber-reinforced article. The method includes the steps of providing a mat fiber stricture defining voids therein. A membrane structure is applied over at least a portion of the fiber structure. The membrane structure includes a microporous membrane. At least the microporous membrane of the membrane structure has an oil resistance rating of at least a number 8 determined by AATCC 118 testing. A resin and hardener mix is provided. The resin is infused into voids of the fiber structure by applying a vacuum to the fiber structure and the membrane structure wherein the membrane structure inhibits the flow of resin therethrough.

    摘要: A porous membrane assembly includes, in an exemplary embodiment, a porous membrane substrate having hydrophobic properties. The membrane substrate includes a first side, an opposing second side and a plurality of pores extending therethrough. The membrane substrate also includes a discontinuous layer of an oleophobic coating applied to the first side so that the plurality of pores in the first side are substantially free of the oleophobic coating, and a continuous layer of an amine containing hydrophilic polymer coating applied to the second side of the membrane substrate.

    摘要: A venting system for a temporary shelter that includes one or more vents that are positioned in the exterior shell of the temporary shelter. Each of the one or more vents may include a membrane that is moisture vapor transmissive and resistant to liquid penetration. The membrane may have a moisture vapor transmissive rate of at least 4,000 g/m2/day. The membrane may be expanded polytetrafluoroethylene. The one or more vents may have a size such that there is approximately 4 m2 of vent surface area in the exterior shell of the temporary shelter per 20 m3 of interior space within the temporary shelter.
