Composite cutting insert and method of making same |
| 摘要 |
A composite cutting insert includes a first portion made of a first composite material, a second portion made of a second composite material, and an intermediate portion interposed between the first and second portions and made of a third material. The intermediate portion has a two dimensional interlocking geometric shape. In one embodiment, the two-dimensional interlocking geometric shape is in the form of a mesh of interlocking links with evenly spaced, uniform small openings between the links. The interlocking geometric shape prevents movement of the first portion relative to the second portion. In addition, the openings allow the first and second composite materials to bond directly to each other. |
