Modified Surfacer Coat for Improving Non-Uniform Composite Surfaces

摘要

A surfacer coat (300, 300′) includes a resin material (302), a plurality of first particles (306, 306′), and a plurality of second particles (308, 308′). The plurality of first particles (306, 306′) and the plurality of second particles (308, 308′) are uniformly distributed through the resin material (302). Each first particle (306, 306′) is of a preselected shape and of a size ranging from about 5 microns to about 10 microns, and each second particle (308, 308′) is of a preselected shape and of a size ranging from about 40 microns to about 50 microns.
