  • SOLID COMPOSITE SHAFT AND SOLID CORE FILAMENT WINDING
    Publication number: 20240262049
    Abstract: A composite shaft or rod formed by filament winding. The composite shaft is a solid shaft and the filament winding does not involve a mandrel. A filament core can be suspended between rotatable spindles and the filament materials can be laid directly onto the filament spindle, without any mandrel. A plurality of payout eyes can be used to simultaneously lay filament materials onto the filament core. A bridge plug can be formed with the solid composite shaft located within the bridge plug shell of the bridge plug.

  • High strength connection for composite sleeve and composite mandrel and related methods
    Patent number: 11401775
    Abstract: A composite downhole tool, such as a frac plug or a bridge plug, having a composite sleeve located around a composite mandrel and defining an overlapping or overlapped section between the two. One or more shear pins with each shear pin having a pin hole is provided with the downhole tool to reinforce the downhole tool from interlaminate shear. The one or more shear pins can further be reinforced from rotation by overlapping at least part of the one or more pins with a lip of a ring.

  • Optimized composite downhole tool for well completion
    Patent number: 10920524
    Abstract: A composite cone assembly for use with a frac or bridge plug system is discussed herein having shaped outer contours and the strength needed for high pressure applications but with reduced machining requirements by forming part of the cone assembly from a high strength fiber material and the contoured surface from molding, such as from injection molding or compression molding.

  • Filament wound composite tools and related methods
    Patent number: 10780671
    Abstract: Composite products and related methods are disclosed. In some examples, methods of filament winding composite components and products, such as a sleeve and/or a mandrel for use in down-hole applications, are disclosed. The winding of components can involve using a percentage of fiber roving strands that are blown during manufacture such that they have fiber loops that when wound as layers forms bridges across the discrete layers to enhance the inter-laminar strength of the composite product.
