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

A hip and ridge shingle includes a base sheet having colored granules adhered to the top surface. A chip is adhered to the base at the trailing edge of the base sheet. A sealant bead is provided parallel to and adjacent the leading edge of base sheet.

Wind resistant roofing shingle

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).

Method and apparatus for the in-line production and conversion of

A method and apparatus are provided for forming a fabric, suitable for mailing a finished composite product, using one or more composite strands. One embodiment of the apparatus comprises at least one bushing for forming reinforcing fibers; supply equipment for supplying matrix fibers; at least one applicator for applying bonding size (i.e., bonding chemical treatment) to the fibers; a gathering mechanism for gathering the treated fibers into at least one composite strand; a pulling mechanism for pulling the at least one composite strand; and a fabric forming mechanism for forming a fabric using the at least one composite strand. One embodiment of the method comprises the steps of drawing a plurality of reinforcing fibers; supplying a plurality of preformed matrix fibers; applying bonding size directly to the reinforcing fibers and the matrix fibers from one or more applicators at least before the reinforcing fibers are gathered together into a strand; gathering the fibers together into at least one composite strand; and forming the at least one composite strand into a unidirectional fabric. The resulting unidirectional fabric comprises a plurality of stitching threads and a continuous glass/polymer composite strand in the form of a plurality of transverse loops. The composite strand can comprise a plurality of first reinforcing fibers drawn from a bushing of molten glass, a plurality of preformed matrix fibers made from a polymer matrix material, and bonding size which bonds together the fibers of the composite strand.

Manufacture of a undirectional composite fabric

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 comprises 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.

A method and apparatus using pneumatic pressure and reduced, controlled clamping pressure to provide reliable, high speed pneumatic forming of thin foil workpieces at ambient temperatures without lubricants or cull plates. Forming elements are provided which incorporate a combination of surfaces and features which enable the reduced, controlled net clamping pressures for forming thin foil workpieces, and control of material slip during forming. Thin foil workpieces formed therewith have reduced incidence of tearing and wrinkling of the foil material. The method is capable of fast cycle times and produces minimal waste.

Method and apparatus for pneumatic forming of thin foil materials

A pair of forming elements incorporate features which restrain a thin foil workpiece without requiring high or excessive clamping pressures. A retaining step is provided in the second forming element having the forming cavity. It has been found that thin foil workpieces bent over and engaged by contact with the retaining step are secured against slippage with reduced clamping pressures. Moreover, the thin foil workpieces exhibit material draw during forming without the excessive lateral pressure between clamping surfaces that causes wrinkles. Substantially wrinkle-free flanges remain in the formed article.
