Date palm reinforced epoxy composites: tensile, impact and morphological properties
In this study date palm stem fibers (DPF)/epoxy composites at different loading (40, 50 and 60 wt.%) were fabricated and their tensile, impact and morphological properties are characterized. The interfacial bonding in tensile fractured samples of composites was examined by scanning electron microsco...
