The primary goal of this study is to determine how well the addition of alumina trihydride (ATH) fillers affects the material properties of hybridised polyester nanocomposites using a weaved jute fibre. The manual lay-up approach was used to create the hybrids, using control variables: (i) ATH filler weight ratio, (ii) stitched jute fiber width, and (iii) amount of stitched jute sheets, altogether at tierce dissimilar stages, to fulfil the goals of this study. By using L9 (33) symmetrical layout, 9 samples were constructed and tested in accordance with the ASTM specification. According to the study by Grey, biocomposites with 6% ATH dust and 250 gsm of weaved jute filaments in tierce have such a satisfactory outcome. Inclusion of dietary fibres to pure synthetic materials improved aggregate material properties. Even as fibre as well as pitch meditations raised, greater power was mandatory to fracture the fibres among matrices as well as their reinforcements.
