Investigation of the mechanical properties of e-glass fabric reinforced SMC around hole on fiberglass reinforced composites materials

In this study, mechanical properties and fatigue damage behavior of E-Glass fiber - polyester perforated SMC and perforated SMC +Glass fabric were investigated. Middle of the samples 10 mm diameter hole was punched with laser beam. Tensile strength experiments performed in accordance with the ASTM D-3039. Fatigue experiments performed in accordance with the ASTM D-3479 standard. Fatigue test was done at R =0,05 stress ratio and 0,75 frequency.
