An asphalt-based roofing material includes a substrate coated with an asphalt coating, a protective coating adhered to the upper surface of the asphalt coating, a layer of granules adhered to the protective coating, and a web bonded to the lower region of the asphalt coating. A method of manufacturing a roofing material includes coating a substrate with an asphalt coating, applying a protective coating to the upper surface of the asphalt coating, applying a layer of granules to the protective coating, and applying a web to the lower region of the asphalt coating.

Storm proof roofing material

Protecting coverings are provided for glass windows and the like. The protective coverings comprise a fiber reinforced polymeric fabric flexible enough to be rolled upon itself.

Protective coverings

Protective coverings are provided for glass windows and the like. The protective coverings comprise impact and puncture resistant protective panels formed from strand material which includes reinforcing fibers and polymeric material.

A reinforced pultrusion product comprises a polymeric matrix, at least one longitudinally oriented buckled reinforcement fiber embedded in said polymeric matrix, and at least one longitudinally oriented linear reinforcement fiber embedded in said polymeric matrix. The product is formed through a pultrusion process wherein a set of composite strands comprising reinforcement fibers and polymeric fibers are provided. A supplemental tension force is applied to a first subset of the composite strands. The composite strands are heated such that the polymeric fibers of a second subset of composite strands shrink to cause the reinforcement fibers in each of the second subset of composite strands to buckle. The heated set of composite strands, including the buckled reinforcement fibers, are consolidated in a pultrusion die.

Transversely and axially reinforced pultrusion product

A method and apparatus is disclosed for the in-line pre-impregnation of glass or synthetic fibers with a non-aqueous chemical treatment. The apparatus includes a first applicator for applying a curable, non-aqueous chemical treatment agent and a second applicator for applying a curing agent for the chemical treatment agent. The fibers are passed over the first and second applicators which are arranged either in parallel or in series, and are then joined by a gathering device to initiate curing of the chemical treatment agent on the fibers. In an alternative embodiment, the apparatus includes a spray gun in which a mixture of the non-aqueous chemical treatment agent and curing agent are sprayed onto an applicator roll in contact with the fibers.

Method and apparatus for the in-line impregnation of fibers with a

A mat is provided which comprises a plurality of strands, each including reinforcing fibers and polymeric material. First portions of the strands are angularly positioned at an angle relative to second portions of the strands and are joined to the second portions via the polymeric material. Also provided is a method for forming the mat.

Reinforcement mat

A method and apparatus is provided for the in-line production of composite strand material and the conversion of at least a portion of the strand material into a composite product. The apparatus (10) includes a combining station (48) where glass fibers (14) with a second polymeric material (66) are combined to form composite strand material (16), and at least one mold (54) for receiving a portion of the composite strand material and forming the portion into a composite product. The apparatus also includes transfer equipment for moving the composite strand material from the combining station to the mold, which may include a computer-controlled robotic arm (52). In another embodiment, the apparatus includes a collecting device (18) for accumulating the composite strand material (16) in looped form and equipment for delivering the accumulated portion from the collecting device to the mold (54). In a further embodiment, the apparatus includes a chopping device (72) for chopping portions of the composite strand material prior to placement into the mold (54).

The improved joule effect glass melt apparatus and method of using the apparatus delivers isothermal glass to a glass forming bushing and reduces the erosion of refractory at high melt temperatures by isolating the refractory from joule effect currents. The glass melt apparatus uses molybdenum liners located on the side walls of the molten glass receptacle to receive joule effect current and provide a uniform temperature distribution through the glass. A molybdenum flow block and molybdenum heat sink located in the flow block complete the heat distribution in the molten glass, achieving an essentially isothermal cross section molten glass upon arrival at the glass forming apparatus or bushing.
