Abstract In this research, mechanical, thermal, and water uptake behaviour of surface-modified sea urchin spike biofiller and kenaf woven fibre mat-reinforced neem oil blended epoxy resin composite has been studied. The principal aim of this research was fabrication of eco-friendly hybrid composite and explicitness of the importance of surface modification on reinforcements. Neem oil was blended with epoxy resin to reduce extreme brittleness of epoxy, making the composite as an eco-friendly one. Sea urchin biofiller was prepared using high energy ball mill. Both filler and fibre were surface-treated by amino silane. The results revealed that additions of surface-treated sea urchin particle and kenaf fibre increased the mechanical properties of composite. Similarly thermal results exposed that addition of sea urchin bioceramic filler greatly increased the thermal stability of neem-epoxy biocomposite. SEM fractographs showed uniform dispersion of sea urchin filler and improved adhesion of kenaf fibre with epoxy matrix. Keywords PMC · Neem oil · Sea urchin fillers/kenaf fibre · Silane treatment
Introduction Natural filler and fibre-reinforced polymer matrix composites are having attractive applications in automobile, construction and aerospace industries due to their eco-friendly nature, light weight, durability and economical process methodologies [1]. Developing eco-friendly composites with natural reinforcements has huge demand in current engineering applications. Generally in composites, the matrix phase possesses large volume than reinforcement phase; hence, matrix modification as a bioform will render more effective eco-friendly applications [2]. Blending of low-cost edible or non-edible natural oils with epoxy resin, the material cost could be reduced, converting the thermosetting resin as a biocompactable one.

thermosetting plastics may reduce the extreme brittleness of matrix phase; hence, the final composite product could be a high toughness material [3]. Neem seed oil (Azardica indica) could be a bioblender to epoxy resin, since it could be mixed with resin with more homogenous manner. The low-cost, high-availability and insect-repellent nature of this biooil is an additional advantage among other biovariants. Reduction of green house gases followed by forestation will be a remarkable benefit by planting more neem trees for oil extraction. In spite of many advantages, ble
