Development of composite panels for short span bridge construction using indigenous agro - based resources: Fabrication and mechanical testing / Ahmad Hussein Abdul Hamid

Bridges are mainly made of steel and concrete. Researchers have been working towards exploring the potential of such new natural fiber composite materials and their adequate application to structural engineering design. Oil palm empty fruit bunch (OPEFB) fiber, oil palm frond (OPF) fiber mat and sug...

Increasing the density of fibers in the composite resulted in reduction of flexural strength, which OPF fiber mat composite has the lowest flexural strength compared to the other composites that being studied.
