  • Patent number: 6755998
    Abstract: A method for making a composite panel includes the step (26) of providing a panel having elongated channels (14) that are positioned along areas of anticipated point compression loading. The panel (10) has a reinforcing fabric layer (41) attached to a non-woven fabric layer (43) forming an outside layer (12). The composite panel has foam core (8,9) within the outside layer. The method further comprises the step (27) of providing structural foam channel inserts (16) having an outer fabric layer (18), wherein the channel inserts have a cross section which matches the cross-sectional profile of each of the elongated channels of the panel. Resin is then applied to the outside layer of the panel and outer fabric layer of the channel inserts such the channel inserts are positioned within the channels of the panel (29 and 31). The resin is then allowed to cure (33) forming a composite structure.

  • Patent number: 6013213
    Abstract: A method of making a resilient composite structure having an exposed reinforcing fabric layer free of structural foam and curable resin and for manufacturing a composite article utilizing the resilient composite structure. The method for manufacturing a composite article includes the steps of positioning at an attachment point within the first plastic shell a resilient foam core composite structure having an exposed reinforcing fabric layer attached to a non-woven fabric layer on one side thereof, the resilient foam core substantially filling interstices of the non-woven fabric layer, without substantially penetrating the reinforcing fabric layer; saturating said reinforcing fabric layer with a curable plastic resin; positioning said second plastic shell on said first plastic shell so that said resilient composite structure contacts an attachment point of said second plastic shell and is compressed between the plastic shells; and allowing said plastic resin to cure.

  • Patent number: 5908591
    Abstract: A method for making a composite structure, comprising the steps of: arranging a fabric layer in a configuration constrained against outward movement and defining a cavity between opposing surfaces of the fabric layer; dispensing a predetermined amount of a self-expanding, self-curable, uncured structural foam into the cavity, the foam expanding and curing in the cavity at a molding pressure determined by the predetermined amount of the foam and thereby attaching itself to the fabric layer to form the composite structure, the molding pressure causing the expanding foam to substantially fill only interstices of an inner portion of the fabric layer, without substantially penetrating an outer portion of the fabric layer; and, freeing the cured composite structure from the constraint of the arranging step, the outer portion of the fabric layer of the composite structure being thereafter substantially completely saturable with a curable material for lamination to another structure in a subsequent processing step.

  • Patent number: 5800749
    Abstract: A composite structure and method of making the composite structure are disclosed. A reinforcing fabric such as fiberglass is mechanically attached, for example, by stitching to a non-woven polyester fabric. The attached fabrics are placed in a mold with the non-woven fabric facing the inside of the mold. A self-expanding, self-curing foam is filled into the mold in an amount sufficient so that upon expansion in the closed mold, the foam penetrates into the interstices of the non-woven fabric which upon curing forms a bond therewith. The resulting structure can be used in a number of applications wherein the reinforcing fabric is later impregnated, for example, with a resin, and allowed to cure. Typical use of such a structure is as a stringer in fiberglass boat construction.

  • Patent number: 4349341
    Abstract: A marine drive has a high aspect ratio, counterbalanced vane on the propulsion unit for generating hydrodynamic torque when rotated. Control cables fastened to a bar on the vane post extend to the rear end of a lever mounted on the steering arm of the marine drive. The forward end of the lever receives the control rod of the boat steering mechanism. Movement of the control rod moves the lever, pulling one or the other control cable and rotating the vane. The lever is so mounted on the steering arm that movements of the control rod are magnified in operating the control cables. Vane rotation may be used to counteract propeller torque components causing course deviations to the boat and to provide torque for turning the marine drive.
