Lignocellulosic/natural fibre and glass fibre-based hybrid composites are considered as high-performance composites but very limited numbers of researchers worked on substituting sugar palm fibre with glass fibre in hybrid composites. The main goal of this research to investigate the effect of various treatment such as 6% alkaline (TNSP), 2% silane (TSSP) and combined 6% alkaline–2% silane (TNSSP) on physical and thermal properties of sugar palm/glass/thermoplastic polyurethane hybrid composites were carried out. Taking into account of physical properties, the combined alkaline–silane treated hybrid composites (TNSSP) showed the lowest density, thickness swelling, and water absorption as compared to other composites. The good thermal stability was discovered for treated as compared to untreated sugar palm fibre based composites (UTSP). Overall, the treated sugar palm/glass/thermoplastic polyurethane hybrid composites suitable for the fabrication of automotive components.
