Abstract
We study the influence of the contents and physical nature of coarse-grained (60–65 μm) and finegrained (3–10 μm) particles on the adhesion strength and residual stresses in epoxy composites for functionally gradient coatings. The temperature-and-time conditions of cross-linking of the epoxy matrix are optimized. The maximum adhesion strength (49.2–50.0 МРа) is attained as a result of the addition of copper-oxide filler (60–65 μm) to the epoxy oligomer in the following amounts: q = 60–80 m.p. per 100 m.p. of the epoxy matrix. The residual stresses vary from 4.5 to 4.8 МРа.
