Fiber orientation measurement from mesoscale CT scans of prepreg platelet molded composites
18 Jul 2019 | Contributor(s): Sergey Kravchenko
X-ray computed tomography (CT) analysis is used to measure the heterogeneous fiber orientation fields in a 20 cm3 composite bracket made from prepreg platelet-based molding compound (PPMC). The as-molded mesostructure of the complete geometry is captured using...
Simulation of prepreg platelet compression molding: Method and orientation validation
Prepreg platelet molding compounds (PPMCs) offer improved performance potential as compared to short-fiber composites and increased geometrical complexity as compared to continuous fiber composites. The increased adoption of PPMCs in automotive and aerospace applications necessitates the...
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....
Analysis of Tensile Properties in a Prepreg Platelet Molded Composite System
