Modeling and Simulation of Fiber Orientation in Injection Molding of Polymer Composites

We review the fundamental modeling and numerical simulation for a prediction of fiber orientation during injection molding process of polymer composite. In general, the simulation of fiber orientation involves coupled analysis of flow, temperature, moving free surface, and fiber kinematics. For the governing equation of the flow, Hele-Shaw flow model along with the generalized Newtonian constit...

N. Modeling and Simulation of Compression Resin Transfer Molding

Accomplishments Analysis of the current modeling approach for CRTM, as well as for some of the physical phenomena involved in the process, such as preform deformation, revealed certain weaknesses in the numerical approach and, more importantly, significant gaps in fundamental understanding of underlying physics. New governing relations for the general Liquid Composite Molding (LCM) and, in part...

3D Representative Volume Element Reconstruction of Fiber Composites via Orientation Tensor and Substructure Features

To provide a seamless integration of manufacturing processing simulation and fiber microstructure modeling, two new stochastic 3D microstructure reconstruction methods are proposed for two types of random fiber composites: random short fiber composites, and Sheet Molding Compounds (SMC) chopped fiber composites. A Random Sequential Adsorption (RSA) algorithm is first developed to embed statisti...

Solution for Carbon fiber Wet-Out Issue for Low Cost Sheet Molding Carbon Fiber Composite Production1 Continental Structural Plastics

Poor wetting leads to underperforming composite properties and has been a major obstacle in implementing low cost carbon fibers in SMC parts. The objective of this project is to solve the technical challenge of poor carbon fiber wet-through during Sheet Molding Composite (SMC) process. Continental Structural Plastics (CSP) partnered with ORNL to develop a new sizing technique called Point Sizin...
