Patent ID: 7854964

Claim:
A method for forming an uncured structure that is suitable for storage at ambient temperatures, said method comprising the steps of: a) providing a porous body comprising an exterior surface and interior surfaces located within said porous body that define interstitial spaces located within said porous body; b) providing a resin composition located at said exterior surface of the porous body, said resin composition forming a cured resin when exposed to a curing agent and heated to a curing temperature that is higher than said ambient temperature, said resin composition comprising: a first non-crystalline component, said non-crystalline component including one or more non-crystalline thermosetting resins; a second non-crystalline component, said non-crystalline component including one or more non-crystalline thermosetting resins; and a crystalline component that comprises one or more crystalline thermosetting resins wherein said crystalline component is located between said first and second non-crystalline components and wherein said one or more crystalline thermosetting resins has a melting point that is above said ambient temperature and below said curing temperature; and c) providing a curative component comprising a curing agent for said resin composition, said curing agent being separated from said resin composition during storage of said uncured structure at said ambient temperatures.
