Vacuum can be applied selectively to permit adjustment of materials at the selected sites, and vacuum is applied continuously to maintain the reinforcing materials firmly against the Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas mold inner surface during application of the fiberglass matting-resin mixture 42 to the reinforcing material upper surface 44 and to the mold inner surface 34 as shown in FIG. Thus, personnel have access to the inside of mold 32 while vacuum is applied externally to the mold to firmly hold the reinforcing material against the mold inner surface during placement of the fiberglass mixture and during adjustment of same.

Next, the vacuum bag 46 is fastened to mold edges 48 in a manner after FIGS. After curing Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas the vacuum is released from the vacuum bag and from the vacuum ports and the composite hull is removed from the mold. The fiber reinforced plastic is readily cured Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas and with some resins may be cured at room temperature, but some may require elevated temperature. A wide variety of reinforcing materials may be used, as polyolefins such as polyethylene Boat Hull Construction Methods Gas or polypropylene; however, desirably the reinforcing material is fiber backed ultra high molecular weight UHMW polyethylene.

Desirably, the aramid fiber backing is in the form of a woven matting Boat Hull Construction Methods Gas with the woven portion facing the mold cavity, which provides excellent sites for the fiberglass matting-resin mixture to form a bond. The fiberglass-resin mixture may use a variety of resins, preferably vinylester or epoxy resins, and desirably a resin with room temperature curing characteristics.

A glass to resin weight ratio of to is employed, although higher glass to resin ratios may be used. A modification of the present invention is shown in FIG. In accordance with FIG. Otherwise, the procedure is as shown in FIGS. A further Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas modified structure, prepared in accordance with the procedure of FIGS. At least one hook or flange 84 is welded to the UHMW polyethylene to serve as an anchor for Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas the applied layers.

In a preferred embodiment shown in FIGS. Note that the UHMW material 70 is stiff and does not conform to the mold shape, nor does it Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas necessarily adhere to tape 86 at this stage. A vacuum bag is then stretched over the mold and vacuum applied as shown in FIGS. This forces the UHMW material Boat Hull Construction Methods Gas to conform to mold inner surface 88, with tape 86 gripping the UHMW material 70 and helping to maintain material 70 in position as it deflects to the position shown in FIG.

While still applying vacuum via the vacuum bag, a second vacuum source is applied to ports 90 so as to maintain the UHMW material in place when the vacuum from the vacuum bag is removed.

After removal of the vacuum from the vacuum bag and after removal of the vacuum bag, the inner surface 88 Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas of the mold and the UHMW material are exposed and accessible for applying the layup material as well as other layers in a conventional fashion.

The second vacuum via Boat Hull Construction Methods Gas ports 90 is maintained during the layup process and during curing. It is to be understood that the invention is not limited to the illustrations described and shown herein, Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas Boat Hull Construction Methods Gas which are deemed to be merely illustrative of the best modes of carrying out the invention, and which are susceptible of modification of form, size, arrangement of parts and Boat Hull Construction Methods Gas details of operation.
