  • Patent number: 11104042
    Abstract: Methods of making a composite article, such as a motor housing, are provided herein. The method can include applying a resin-fiber material to a shaped surface to form an intermediate article. The resin-fiber material includes an uncured resin composition and a fiber substrate material. The method further includes solidifying the uncured resin composition present in the intermediate article to form the composite article. Solidifying can be accomplished by applying heat to the intermediate article to initiate an exothermic reaction comprising polymerization, cross-linking, or both of the uncured resin composition. Application of the heat from the heat source can be ceased after initiation of the exothermic reaction, but polymerization, cross-linking or both of remaining uncured resin composition can continue in one or more of a radial, circumferential, or axial direction through a thickness of the resin-fiber material in the absence of heat from the heat source to form the composite article.

  • Patent number: 9109752
    Abstract: Provided is a pressure vessel able to sustain a circular shape without deforming to ellipsoidal shape due to machining of side port apertures therein, and maintain pressures as high as 800-1,200 PSI. The pressure vessel is intended for use in seawater desalination by reverse osmosis, and comprises a pipe body (1) formed by filament winding (FW), and is furnished with an occluding cover (2) at each end of the pipe body (1), the peripheral surface of the pipe body being furnished, inward from the occluding covers (2), with inflow/outflow parts (3) through which the fluid flows in or out. The pipe body (1) is constituted by a helical layer (4), hoop layers, and a seal layer (6) furnished as the innermost layer. The helical layer (4) is furnished with a divergent part (7) diverging away from the seal layer (6) and extending from a location outward from the occluding cover (2) to a location inward from the inflow/outflow part (3).

  • Patent number: 8991641
    Abstract: A toroidal pressure vessel having extremely high pressure resistance has laminated latitudinal reinforcing fiber layers to improve a strength in a latitudinal direction of the pressure vessel. Moreover, putting reinforcing fibers constituting those laminated latitudinal reinforcing fiber layers in continuity enables further improvement of strength in the latitudinal direction of the pressure vessel, for example compared with a case where the reinforcing fibers are divided for each layer.
