FIBER-REINFORCED TOOLS FOR DOWNHOLE USE |
| 摘要 |
A wellbore tool may be formed, at least in part, by a fiber-reinforced hard composite portion that comprises a binder, matrix particles, and reinforcing fibers, wherein the reinforcing fibers have an aspect ratio ranging from equal to a critical aspect ratio (Ac) to 15 times greater than the Ac, wherein Ac=σf/(2Tc), σf is an ultimate tensile strength of the reinforcing fibers, and Tc is an interfacial shear bond strength between the reinforcing fiber and the binder or a yield stress of the binder, whichever is lower. |

1. A wellbore tool formed at least in part by a fiber-reinforced hard composite portion that comprises a binder, matrix particles, and reinforcing fibers, wherein the reinforcing fibers have an aspect ratio ranging from equal to a critical aspect ratio (Ac) to 15 times greater than the Ac, wherein Ac=σf/(2Tc), σf is an ultimate tensile strength of the reinforcing fibers, and Tc is an interfacial shear bond strength between the reinforcing fiber and the binder or a yield stress of the binder, whichever is lower. |
