Structure-property relationship for a prepreg platelet molded composite with engineered meso-morphology

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

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...

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...

Tensile Properties of a Stochastic Prepreg Platelet Molded Composite

17 Jul 2019 | Contributor(s): Sergey Kravchenko, Drew Sommer, Benjamin Denos, Tony Favaloro, Byron Pipes, William Avery, Clark Tow

The stochastic prepreg platelet molded composite (PPMC) occurs when the orientation and arrangement disorder of platelets are determined by the uncontrolled molding conditions. The understanding of composite structure-property relationship is essential for the engineering applications of PPMCs....
