Abstract
A door assembly comprising a pair of relatively thin reaction injection molded skins adhered on opposite sides of a perimeter frame. A core comprised of a relatively rigid plastic foam is disposed within the frame. The reaction injection molded skins comprise a composite containing a reaction injection molded resin such as a polyurethane resin, and a reinforcing fibrous mat such as a glass mat which is impregnated with said resin.
Claims39
A door assembly comprising:
- (i) a frame containing two opposite sides, a top rail, a bottom rail, a first stile adapted to receive a lock mechanism, and a second stile adapted to receive at least one hinge;
- (ii) a core comprised of plastic foam disposed within said frame;
- and
- (iii) a skin having comprised of reaction injection molded resin having an exterior surface and an interior surface disposed on each of said opposite sides of said frame covering substantially all of said frame and said core and adhered to at least said frame.
A door assembly according to claim wherein said interior surface of said skin has a textured pattern effective to promote adhesion of said skin to said frame and core.
A door assembly comprising, in combination:
- (i) a perimeter frame comprised of wood defining a central cavity;
- (ii) a core comprising a plastic foam disposed in said cavity;
- and
- (iii) a pair of opposed skins comprised of glass fiber mat reinforced reaction injection molded resin mounted on said frame.
A door assembly comprising:
- (i) a wooden rectangular perimeter frame having two sides comprised of (a) a top rail comprised of a plurality of wood plies, (b) a bottom rail comprised of a plurality of wood plies, (c) a first stile adapted to receive a latch mechanism comprised of a plurality of wood plies, and (d) a second stile adapted to receive at least one hinge;
- (ii) a foam core positioned within said frame;
- and
- (iii) a composite skin having an exterior surface and an interior surface mounted on each of said sides of said frame, said composite skin comprising a fibrous mat impregnated with a reaction injection molded resin.
