The Influence of Microstructural Variability upon the Scatter in Mechanical Properties of R25 Sheet Molding Compound

Source

The large scatter in the static strengths of R25 sheet molding compounds was observed to be related to the variability in the complex microstructure of this material. This microstructure consists of a subsurface veil of individual glass fibers and an internal core of intact fiber glass bundles.
