In this work peanut oil cake extracted Cellulose Micro Filler (CMF) is used for the advancement of mechanical and thermal properties in natural fiber composites. This fiber powder was used in enhancing the applications of Pineapple (P)/Flax (F) natural fiber epoxy composites. The X Ray Diffraction (XRD) results of CMF showed improved Crystalline Index (Crl) of 70.25° and crystalline size of 5.5 nm. FTIR results confirmed the rich cellulose content in functional groups of filler with peaks at 1058 cm-1, 1162 cm-1, 1370 cm-1 and 1428 cm-1. Mechanical results showed a positive impact with incorporation of CMF in PF hybrid fiber composites. Thermal stability results showed enhancement in the degradation temperature, residual %, endothermic peak and enthalpy by the incorporation of CMF. In the 30% PF combinations degradation temperature T50, T70, T70 enhanced from 387.73-391.08°, 434.81-454.81° and 468.91-553.36° by the filler substitution. Similarly residual % increased from 17.69-24.35%. The combination with 35% PF showed enhancement in degradation temperature, residual percentage, endothermic peak and enthalpy with filler addition up to 3%. Copyright © 2020 Elsevier B.V.
