## Abstract The increase in modulus obtained in a shortโglassโfiberโreinforced polymer composite as a result of uniaxial deformation may be related to the observed increase in both fiber and matrix orientation. Quantitative measurements of both fiber and matrix orientation are presented for a serie
## Abstract A computer simulation has been developed to predict the orientation of fibers in a thin, flat part that is compression molded from sheet molding compound. The simulation combines a finite element/control volume simulation of the mold filling flow, a second order tensor representation of
## Abstract Fiber orientation induced by injection mold filling of shortโfiberโreinforced thermoplastics (FRTP) causes anisotropy in material properties and warps molded parts. Predicting fiber orientation is important for part and mold design to produce sound molded parts. A numerical scheme is pr
## Abstract Liquid crystalline polyesters as host polymers and paramagnetic metal complexes as guest molecules were prepared, and meltโdrawn fibers were made from their blend at mesophase temperature. The wideโangle Xโray diffraction patterns of the fibers indicated that the nematic or smectic phas
