Effect of Laser Shock Peening on the Fatigue Behavior and Mechanical Properties of Composite Materials

In this study, Laser Shock Peening (LSP) effect on the polymeric composite materials has been investigated experimentally. Polymeric composite materials are widely used because they are easy to fabricate and have many attractive features. Unsaturated polyester resin as a matrix was selected and Alu...
