  Abstract

This research is conducted to evaluate the mechanical and water absorption behavior of the composite pipes based on polyester resin reinforced with pineapple fiber, porous biochar and biosilica filler particles. Prepreg approach was utilized to fabricate the composites reinforced by 40 vol.% pineapple fiber and two different filler reinforcement (porous biochar, biosilica) with varying ratios. After fabrication, the composite pipes were subjected to flexural, hardness, flat-wise and edgewise compression and water absorption tests, followed by the relevant American society of testing and materials (ASTM) standards. From the result data, the mechanical properties of the 3 vol.% biosilica incorporated composite PS3 exhibited higher flexural strength values of 32.47 N/mm2, flatwise compression strength of 18.91 N/mm2 and edgewise compression strength of 21.82 N/mm2. In contrast, the composite P (with 40 vol.% pineapple fiber) showed least water absorption ability of 1.66%. Additionally, Scanning Electron Microscopy (SEM) analysis was employed to study the surface topography of the fractured tested specimen surfaces. It is evident that biosilica incorporated composites have superior mechanical properties, increased hardness, and improved interfacial bonding and these composites are better suited for load-bearing and pipeline applications. Furthermore, their altered composition allows for better performance under varying environmental conditions, making them perfect for industrial and structural applications such as automotives, sports, defense, infrastructure and aviation.
