Abstract
Ordered elastomeric composites comprise an ordered arrangement of a number of first elastomeric phases distributed uniformly within a continuous matrix second elastomeric phase. The second phase can be formed from an elastomeric material that is relatively harder than an elastomeric material that is used to form the first phases. Each first phase can be in the form of a core having a defined length and diameter, and the second phase can be formed from a number of shells that each surround a respective core. In a preferred embodiment, the arrangement of cores and shells are aligned coaxially with one another to provide a cellular structure. Ordered elastomeric composites of this invention can be used to form part of or an entire elastomeric seal, e.g., in the form of an annular ring adapted for use in a rotary cone drill bit.
