A fiber reinforced core is formed from plastics foam material having elongated porous and fibrous webs and/or rovings extending through the foam material. The rovings may extend angularly through the webs, and strips of the foam material may be helically wound with layers of crossing rovings to form the webs. Porous and fibrous skins for the core may be formed by the wound rovings and by parallel continuous rovings, and the foam strips may be formed with internal grooves adjacent the webs and connected by a feeder channel for infusing a hardenable adhesive resin into the grooves and outwardly through the webs to the skins with differential pressure on the resin.

Fiber reinforced composite cores and panels

An outer skin or facing of wood sheet material and an inner skin or facing of wood sheet material are adhesively bonded to opposite sides of a core of rigid expanded foam material to form an elongated wall unit having a horizontal length greater than its vertical height. A longitudinally extending upper portion of the wall unit incorporates adhesively bonded members which form an integral continuous beam extending horizontally from one end of the wall unit to the opposite end. The integral beam has a vertical height substantially greater than its thickness for supporting a substantial load above a door or window opening which may be subsequently formed within the wall unit at any selected location between the ends of the wall unit. A plurality of spaced wood furring strips are adhesively bonded to the inner facing of the wall unit and are provided with channels adjacent the inner facing for receiving electrical wiring. The furring strips also function to strengthen the wall unit against wind deflection and provide for an air space between the inner facing and gypsum dry wall sheeting which is subsequently attached to the furring strips. In one embodiment, the beam is formed by wood members which are vertically spaced between the facings to form a box beam. In another embodiment, thin sheets of metal are bonded by adhesive to the inner surfaces of the facings and to the foam core panels which are uniform in thickness throughout the entire wall unit.

Composite wall panel assembly and method of production

An outer skin or facing of wood sheet material and an inner skin or facing of wood sheet material are adhesively bonded to opposite sides of a core of rigid expanded foam material to form an elongated wall unit having a horizontal length greater than its vertical height. A longitudinally extending upper portion of the wall unit incorporates adhesively bonded members which form an integral continuous beam extending horizontally from one end of the wall unit to the opposite end. The integral beam has a vertical height substantially greater than its thickness for supporting a substantial load above a door or window opening which may be subsequently formed within the wall unit at any selected location between the ends of the wall unit. A plurality of spaced wood furring strips are adhesively bonded to the inner facing of the wall unit and are provided with channels adjacent the inner facing for receiving electrical wiring. The furring strips also function to strengthen the wall unit against wind deflection and provide for an air space between the inner facing and gypsum dry wall sheeting which is subsequently attached to the furring strips. An integral continuous beam may also be located within a lower portion of the unit. In one embodiment, the beam is formed by members which are vertically spaced between the facings to form a box beam, and in another embodiment, the vertically spaced beam members are bonded only to the inner facing to form a 'C' shaped continuous beam.
