Phenol formaldehyde was filled with Envirospheres slg to increase the strength of the composite for structural applications by a research center on composites, University of Southern Queensland (USQ). In order to reduce costs, the center wished to fill with as much slg as possible, subject to maintaining sufficient strength of the composites in structural applications. This project varied the wt% of the slg in the composites which were then subjected to flexural tests. The results showed that composite with 25 wt% of the slg produced the highest flexural strength and Young’s modulus combined with a reasonable fluidity for casting; the highest flexural strain was achieved when the slg was 10 wt%.
