Peanut oil cake-derived cellulose fiber: Extraction, application of mechanical and thermal properties in pineapple/flax natural fiber composites

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 degrees and crystalline size of 5.5 nm. MR 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 PP 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% PP combinations degradation temperature T-50, T-70, T-70 enhanced from 387.73-391.08 degrees, 434.81-454.81 degrees and 468.91-553.36 degrees 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%. (C) 2020 Elsevier B.V. All rights reserved.
