“…The presence of high strength fiber at the skin layer results in more flexural strength values. The observed results also get matched with the results suggested by Nampoothiri et al [ 16 ]. The presence of higher moisture content in banana fiber resulted in less flexural strength values in the case of C-1 composites.…”

Nonbiodegradable polymers constitute major pollution and their usage cannot be ignored due to their properties. Hybrid polymer composite research has increased in recent times due to improved characteristics and biodegradable nature. The effect of different stacking sequences containing pineapple/banana/basalt fiber has been studied in the present work to reduce the usage of synthetic fibers without compromising on properties. Hybrid composites were manufactured using the hand layup method and were assessed for mechanical and morphological characteristics. The results showed that several properties improved by keeping the pineapple layer in the skin layer. The adhesion between the matrix and the fiber played a vital role in determining the properties of the composites manufactured. Morphological studies have concluded that the proper bonding between the matrix and the fiber has enhanced several properties.

Current study employs reinforcement of untreated (GSP) and alkali treated groundnut shell powder (T-GSP) to the thermoplastic acrylonitrile-butadienestyrene (ABS) matrix for the fabrication of composites. Interactions of alkali to the cellulose, hemicellulose, and lignin of T-GSP was confirmed from the ATR-IR analysis. The most significant tensile strength (54.78 MPa) and modulus (2.78 GPa) was reported for 20 wt% T-GSP reinforced ABS composite. Additionally, greatest flexural strength and modulus of 88.30 MPa and 7.80 GPa was recorded for the composite constitutes 20 wt% T-GSP and 80 wt% ABS.The highest and lowest notched impact strength of 15.85 kJ/m 2 and 13.52 kJ/ m 2 were reported for the composites consist of 10 and 20 wt% of T-GSP. Composite 20/80 T-GSP/ABS exhibited highest shore D hardness value of 90. Morphology was studied using FE-SEM characterization and reports excellent wetting of T-GSP particles from ABS. Composites reinforced with 10 wt% of T-GSP exhibited highest (~269 C) while one reinforced with 20 wt% of the T-GSP showed lowest thermal degradation point (~259 C) throughout the temperature range. Differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) analysis shows an increment (1-6 C) in the glass transition temperature of all the composites compared to pristine ABS irrespective of treatment.alkali-treatment, acrylonitrile-butadiene-styrene, groundnut shell powder, notched impact strength, thermoplastic composites | INTRODUCTIONComposites materials are essential in many forms for the survival of human life, and they may be structural, [1][2][3][4] functional, [5,6] or biomaterial.

The global trend of environmental protection has led to replacing synthetic fibers in every feasible application with natural fibers. An alteration of the fiber's surface is essential for the natural fiber to be more suitable for use. In this study, the mercerization processes including 5% (wt/vol) sodium hydroxide solution at five different soaking times (15, 30, 45, 60, and 75 min), were used in this study to enhance various features of Ziziphus nummularia fibers isolated from Ziziphus nummularia plant stems. Results showed that 60 min alkalized Ziziphus nummularia fibers had cellulose content of 65.72%, which seems to be higher, and it was termed as optimally alkalized Ziziphus nummularia fibers. The thermal studies showed that optimally alkalized Ziziphus nummularia fibers had a degradation temperature of 360 C. The optimally alkalized Ziziphus nummularia fibers showed a crystalline index of 50.6% and crystal size of 3.52 nm. Epoxy composites were manufactured with various loading percentages of optimally alkalized and raw Ziziphus nummularia fibers to prove the application suitability. It was shown that 20 wt% of optimally alkalized Ziziphus nummularia fibers-based epoxy composites showed a higher ultimate tensile strength of 40.31 MPa than all other composites. Scanning Electron microscope studies elucidated the fiber's surface behavior and other characteristics of fibers and tested epoxy composites.
