Effect of platelet length and stochastic morphology on flexural behavior of prepreg platelet molded composites

Prepreg platelet molding compound (PPMC) can be used to create structural grade material with a heterogeneous mesoscale morphology. The present work considered various lengths of the prepreg system IM7/8552 study effect length on flexural behavior PPMC composite. A progressive failure finite-element analysis was understand competing modes in different length. interlaminar and in-plane damage mechanisms were employed describe complex within mesostructure PPMCs. Experimental results tests sizes validate modeling prediction. experimental revealed mechanical properties (modulus strength) indicate that composites processed plate 12.7 mm have higher modulus strength than 25.4 6.35 mm. attributed interactions between stochastic fiber orientation distribution variability material.
