摘要： A process, and apparatus for the production of fiber reinforced plastic structures, particularly high strength fiber reinforced plastic structures via an improved vacuum assisted technique. In apparatus which includes a fluid impervious outer sheet, or bag, provided with a resin inlet, marginally sealed upon a mold to provide a chamber in which can be place a fiber lay up and which in turn is provided with a vacuum outlet there is provided a resin distribution medium for location on one side of the fiber lay up of character which permits on application of a vacuum the ready, continuous flow of resin via the resin inlet into the chamber to the marginal edges of said resin distribution medium. Closure of the outer sheet, or bag, with the fiber lay up is prevented by the presence of the resin distribution medium while the flow of resin is continued throughout the resin distribution medium, the resin applied to one side of the fiber lay up, and the resin cured. The fiber reinforced plastic structure is removed from the mold after the resin has cured by peeling away the outer sheet, or bag, and resin distribution medium. The strength of the fiber reinforced plastic structures, and fiber reinforcement-to-plastic ratios are of quality and strength approximating structures made by the more complex prepreg-autoclave processes.
摘要翻译：一种通过改进的真空辅助技术生产纤维增强塑料结构，特别是高强度纤维增强塑料结构的方法和装置。在包括具有树脂入口的不透液体的外部片材或袋子的装置中，边缘密封在模具上以提供可以放置纤维铺设的室，并且还设置有真空出口用于位于纤维一侧的树脂分配介质，其特征在于，允许通过树脂入口将准备好的连续流动的树脂施加到真空室中，从而将树脂入口进入室中至树脂分配介质的边缘。通过树脂分配介质的存在可防止外层片材或袋子与纤维铺放在一起，同时在整个树脂分布介质中继续树脂流动，施加在纤维一侧的树脂铺设，树脂固化。通过剥离外部片材或袋子和树脂分配介质，树脂固化后，将纤维增强塑料结构从模具中除去。纤维增强塑料结构的强度和纤维增强塑性比是由更复杂的预浸料 - 高压釜工艺制成的质量和强度近似结构。

摘要： The hull of a wooden vessel is laminated and provided with an outer plastic skin which provides a hull of high structural strength, and protects the wood interior against rot and attack by marine organisms. In its preferred aspects, a skin of fabric-like fiberglass is chemically bonded (and preferably chemically and mechanically bonded) to a wooden hull constituted of wooden planking at least three-fourths inch in thickness by use of an elastomeric adhesive which, after curing, is capable of stretching at least twice, and preferably from about 3 to about 5 times its length, and the outer surface of the fabric-like fiberglass is saturated with resin, covered with a chopped fiberglass mat, cured, a fairing compound is applied to the exterior of the skin, and the surface is sanded and painted. The laminated structure is highly resistant to stresses produced by expanding, contracting and bending, particularly prevalent in thick wooden hulls, which tend to produce delamination between the skin and the working hull.

摘要： A new and further improved multi-ply fabric, and process for the manufacture of such fabric, particularly useful in boat building wherein the fabric must fit or assume the shape of compound-curved surfaces to suitably serve as a base or support for resin or liquefied plastics added thereon and cured or hardened as an initial step in the formation of, e.g., a fiberglass reinforced plastic boat hull. The fabric is characterized generally as of a two-ply construction embodying an upper and lower ply between which is "sandwiched" and secured a series of parallel aligned, spaced apart, springy elements of specific character between which can be placed yarns or rovings to impart tensile strength. The plies of the fabric consist of parallel aligned, continuous, pliable filaments bonded to said springy, plastic elements, each filament being laterally aligned with respect to said springy elements, the filaments being sufficiently pliable or flexible to permit some lateral or transverse movement, and also longitudinal movement, of the springy elements so that the fabric construction can assume compound-curved shapes.
