Rheology of Carbon Fiber Thermoplastic Polymer Composites
26 Apr 2021 | Online Presentations | Contributor(s): Byron Pipes
The rheology of fiber–reinforced thermoplastic composites will be presented with specific focus on several topics studied over the past three decades. Interest in the elongational viscosity of collimated, discontinuous fiber systems was initiated by the introduction of impregnated,...
Constitutive modeling for time- and temperature-dependent behavior of composites
08 Jan 2020 | Publications | 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...
Structure-property relationship for a prepreg platelet molded composite with engineered meso-morphology
17 Jul 2019 | Publications | 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 | Publications | 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...
