No. 15/632,062, filed Jun. 23, 2017 and now issued as U.S. Pat. No. 10,252,445, which claims the benefit of priority from U.S. Provisional Patent Application Ser. No. 62/354,472, filed Jun. 24, 2016, the disclosures of which are hereby incorporated by reference in their entireties.
- The present disclosure generally relates to methods and devices for injection of resins and similar materials. More specifically, the present disclosure relates to a system comprising a manifold for injecting and controlling the injection of resins. Systems of the present disclosure comprise a plurality of flow ports for the controlled application and dispensation of a resin or similar material into a mold, a structure, a part, or a similar item.
- Vacuum assisted resin transfer molding (VARTM) and related processes and techniques have been widely used to fabricate relatively large fiber-reinforced composite articles. Such articles include articles of various sizes including turbine blades, ship hulls, etc.
- U.S. Pat. No. 6,216,752 to Bailey, which is hereby incorporated by reference in its entirety, discloses a gravity feed resin distribution system. Proper application of resin is important for avoidance of structural weaknesses and deficiencies of the resultant article. Bailey, however, fails to disclose various novel features of the present disclosure, as shown and described herein.
- There exists a long-felt and unmet need in the art for an improved device for enhancing and simplifying resin distribution in comparison to the prior art. In various embodiments of the present disclosure, manifold assemblies, devices, and methods of use thereof for resin infusion processes and similar operations are provided. In certain embodiments, valve-controlled pipe manifold assemblies are provided. The valve-controlled pipe manifold assemblies of the present disclosure preferably comprise a plurality of outlet ports that lead to varying lengths of hose to ensure even coverage and cure of the resin over the required surface.
- In certain embodiments of the present disclosure, a resin infusion and/or application process is contemplated. The resin infusion process contemplates “pulling” at least one resin through a system or product by using a negative pressure differential (i.e. vacuum). An internal pressure within an assembly or manifold may range from 3 to 10 mbars (mbar=one thousandth of a bar, the centimeter-gram-second system unit of atmospheric pressure equivalent to 100 Pascal's.)
- It will be expressly recognized that the present disclosure is not limited to any particular resin, or the use of any particular resin. In various embodiments, however, it is contemplated that a resin is applied at an approximate temperature of between approximately 30° Celsius and approximately 50° Celsius, and preferably at about 39° Celsius (102° Fahrenheit) during an infusion process.
- In preferred embodiments, a pipe manifold for resin application and infusion processes is provided. The pipe manifold preferably comprises stock aluminum, but may comprise various other materials, materials and combinations thereof. Pipe manifolds of the present disclosure may comprise various dimensions, sizes, and proportions based on a desired application. In certain embodiments, however, it is contemplated that a manifold is provided comprising an aluminum body portion with a thickness of approximately 1.50 inches and a width of approximately 2.00 inches. Such body portions are contemplated as withstanding the stress (from vacuum pressure, for example) and heat associated with various molding operations while still providing a light-weight and cost-effective component. In various embodiments, manifolds of the present disclosure are contemplated for use as vacuum-assisted devices, wherein resin is moved through the manifold at least in part due a vacuum force at the injection outlets. Various existing technologies generally fail to provide the proper structure, heat resistance, etc. to withstand the demands of such processes and various components and features as shown and described herein are provided as non-obvious solutions to issues associated with prior art devices.
- In one embodiment, a pipe manifold is provided comprising one inlet port and a plurality of outlet ports (e.g. 2-6 outlet ports).

The first outlet port is located approximately 3.25 inches from an inlet end of the assembly, and the remaining transverse outlet ports are spaced approximately 5.00 inches apart thereafter.
- In one embodiment, a pipe manifold comprises a length of between approximately 5.0 inches and approximately 20.0 inches, and preferably of approximately 11.75 inches. An inlet port and the final outlet port are preferably collinear and spaced apart by the length of the part. A remaining plurality of ports are orientated transversely to the length of the part, along a 1.50″ thick surface. The ports are each preferably oriented substantially perpendicular to the inlet port and the outlet port.

Certain applications may require the movement of a resin application manifold as shown and described herein in order to evenly apply a resin or similar coating over a large area (e.g. during manufacture of large items such as ship hulls). Accordingly, embodiments of the present disclosure contemplate providing a manifold on a track and providing the manifold as a motor-driven unit that is controllable and moveable by a user in at a constant velocity over a given distance.
- Although specific embodiments are disclosed herein, wherein manifolds comprise various specific dimensions, it will be recognized that the present disclosure is not limited to such dimensions or to manifolds of any particular dimension(s). Manifolds of the present disclosure may be scaled up or down and/or varied in proportion.
