3-D Numerical Realization of Contituent-Level FRP Composites Using X-Ray Computer Tomography

Completed Technology Project

Project Introduction

Develop met . hods coupling state-of-the-art, nondestructive characterization techniques with three-dimensional, numerical modeling to study the constituent-level failure of fiber-reinforced polymer (FRP) composites

The objective of the project is to initiate realization of the Digital Twin concept for composites by coupling state-of-the-art, nondestructive characterization techniques with 3D numerical modeling to study the constituent-level failure of FRP composites. Near-term implications for this work include significantly increasing our understanding of the fundamental, constituent-level, failure mechanisms in current FRP composites through ultra-realistic, multi-physics simulations. The work will have long-term impacts on the design of innovative composites by virtual testing and on the incorporation of composites into the Digital Twin framework. The initial benchmark for success will be the high resolution (i.e. 385 nm) characterization, reconstruction, and finite element discretization of an approximately 130×130×130 mm3 volume of unidirectional graphite/epoxy composite (e.g. IM7/8552, AS4/3501-6).
