Bridge railway sleepers has been made from sandwich structured composite that the components are ; fiberglass, epoxy resin, filled with honeycomb PP, coconut, bagasse fiber, and polyurethanes as adhesive. Baggase has a light density, whereas honeycomb PP is hydrophobic, chemical subtantace resistant, and readily available. The sandwich structure in composite improves the flexural rigidity 8 times higher that the solid ones.
