Abstract

Two specimens were prepared in this study, i.e., film insert molded (FIM) specimens and short glass fiber reinforced FIM specimens in order to evaluate reinforcing effect of short glass fibers on warpage of FIM composite (FIMC) specimens. Anisotropic properties induced by short glass fibers were considered for three-dimensional numerical analysis of the specimens to predict fiber orientation and warpage of the FIMC parts. The FIM specimen was bent such that the film side was protruded, but the warpage was reduced gradually with reinforcing glass fibers (GFs) and the FIMC specimens with GFs of 20 and 30 wt% were bent such that the film side was concave. Comparison between experimental and numerical results was carried out in this study.
