Abstract:
1. A composite article comprising: a support structure comprising a recessive phase matrix material and a protrusive phase material that forms a plurality of spaced apart, essentially parallel cores within said recessive phase matrix material, said recessive phase matrix material being different from protrusive phase material, said plurality of cores defining a plurality of spaced apart surface features, each of said surface features comprising a distal end opposite said support structure, integrated with said support structure, and protruding distally from a surface of said support structure, each of said surface features reducing in cross sectional area distally from said support structure to provide a lowest cross sectional area at said distal end, said recessive phase material supporting and separating said surface features and defining a contiguous recessed surface area between said surface features.
