Research on Damping of Foamed Al Composite Filled Epoxy Resin in the Holes
Damping of foamed Al composite filled epoxy resin in the holes is researched by experimental and theoretical analysis. The results are showed that foamed Al damping can be improved by Filling epoxy resin in the holes, and with porosity increasing or diameter decreasing, the composite’s Damping is increased, but the change of damping with frequency is non- monotone function. The results can provide reference for optimization and application of the composite.
