Constitutive modeling for time- and temperature-dependent behavior of composites
08 Jan 2020 | Contributor(s):: Orzuri Rique, Xin Liu, Wenbin Yu, Byron Pipes
Structural integrity, durability, and thermal stability represent critical areas for adequately modeling the behavior of composite materials. Polymeric matrices are prone to have time-dependent behavior very sensitive to changes in temperature that influence the effective properties of the...

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....

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...
