Abstract
A filament-reinforced composite material having with load-aligned filament windings enables improvement of mechanical properties for specific loading of parts made from the material. The orientation of the winding within the part may be changed depending on an orientation of an external load to the part. In one example, the part may be a slip in a frac plug or a bridge plug in a downhole application.
Claims16
A filament-reinforced composite slip, comprising:
- a matrix phase comprising a cross-linked polymer;
- an inclusion phase comprising filaments having a first orientation at a first end of the slip and having a second orientation at a second end of the slip opposing the first end, wherein the first orientation and the second orientation run at different angles with respect to an outer surface of the slip;
- wherein the first orientation is substantially parallel to the outer surface of the slip at the first end;
- wherein the filaments terminate in the outer surface of the slip at the second end;
- and
- wherein the outer surface of the slip is enabled to engage an inner surface of a wellbore to secure a downhole assembly in the wellbore.
