   The objective of this work was to develop a finite-element based computational model to investigate the complex three-dimensional load transfer from the known meso-structure of a prepreg platelet molded composite (PPMC) system with a layered planar morphology and...

5. Uniaxial strength of a composite array of overlaid and aligned prepreg platelets

   17 Jul 2019 | Contributor(s): Sergey Kravchenko, Drew Sommer, Byron Pipes

   The tensile strength of a discontinuous composite system consisting of aligned, unidirectional prepreg platelets is predicted by performing progressive damage analyses in a periodic representative volume element. Interlaminar and in-plane damage mechanisms are combined to...
