“…Alkali and microwave treatment of coir fibers were performed as follow: the coir fibers without sodium hydroxide treatment were treated using irradiation microwave. Such fibers were exposed in the microwave oven at different times including 10 minutes (M10) and 20 minutes (M20)) [9]. Then, the treated coir fibers of sodium hydroxide were exposed in the microwave oven with irradiation microwave at different times (10 minutes (NM10) and 20 minutes (NM20)) without heating in the oven.…”

In this study, coir fibers were surface treated with alkali and microwave treatments. The effect of alkali and microwave treatments of coir fibers as reinforcement of coir fiber/polyester composite on water absorption and mechanical properties (tensile, flexural and impact strength) was reported. Treatments were divided into two types: microwave treatment of coir fibers for 10 minutes (M10) and 20 minutes (M20) without alkali treatment; and alkali treatment of coir fibers with soaking during 24 hours in 5w/v% NaOH solution, followed by heating in the oven for 2 hours (2N) and also followed by microwave treatment during 10 minutes (NM10) and 20 minutes (NM20). Coir fiber then was pressed like mat which was used as reinforcement of polyester composite. Hand lay-up technique with compression molding was used to fabricate composite. The water absorption and mechanical properties like tensile strength, tensile modulus, flexural strength and impact strength were studied. Fracture of tensile testing was evaluated by Scanning Electronic Microscopy (SEM). The results obtained showed that alkali and combination of alkali and microwave treatment improved significantly the water absorption of the composite. For mechanical properties of the composite, alkali and microwave treatments of coir fiber tend to increase tensile strength, tensile modulus, flexural strength and impact strength. However, for both M10 and NM20 treatments, the flexural strength of composite decrease due to the poor adhesion between fiber and matrix in the composite. Then, SEM characterizations show treated fiber improved the adhesion fiber-matrix in the composites.

“…The utilization of microwave irradiation presents a highly promising approach for the surface transformation of natural fibers [8]. The implications of the effect of microwave irradiation on empty fruit bunch (EFB) fiber were investigated in a study conducted by B. Bakari et al [9]. The tensile strength experienced a significant increase from a value of 142.40MPa to a value of 187.25MPa after subjecting the fiber to microwave irradiation for a duration of 10 minutes.…”

The present study used Calotropis Gigantea fiber, which has minuscule significance in vegetation value, and waste Nelumbo Nucifera filler for the production of polymer composites. The Calotropis gigantea yarn fiber is twisted into Two-Ply Yarn and subsequently woven into mats, the mat underwent both NaOH treatment and microwave irradiation in order to enhance their compatibility with epoxy. This work aims to examine the mechanical and dynamic properties of a hybrid composite material consisting of a Chemically and Microwave Treated Calotropis Gigantea (CMTCG) fiber combined with Nelumbo nucifera (NN) infills. The objective of this study is to investigate the possible improvement of the mechanical and dynamic characteristics of polymer composites by developing composite samples that include different weight proportions of NN fillers in CMTCG-reinforced Epoxy composites. The assessment of the mechanical properties of several combinations of CMTCG with NN infills was conducted utilizing established testing methodologies, including tensile, flexural, impact, and Dynamic Mechanical Analysis (DMA) to assess the viscoelastic nature of the composites. In addition to this, a Cole-Cole curve is plotted by utilizing the findings of the DMA to analyze the effect of particle impregnation and the anticipation of the heterogeneity of the composite material at different loadings of fillers. The current investigation revealed that a fiber loading of 10 weight percentages represented the optimal threshold, and any loading value resulted in a noticeable decline in all characteristics.

This research examines the characteristics of microwave assisted pyrolysis products of cashew nutshell waste (CNS). The pyrolysis process of CNS conducted with microwave heating of 400 W for 60 minutes. Pyrolysis product such as bio-gas, bio-oil and bio-char were identified using proximate and ultimate analysis, scanning electron microscope (SEM), thermogravimetric analysis (TGA/DTG), gas chromatograph-mass spectrometer (GC-MS) and Fourier Transform InfraRed (FTIR) Method. There is a significant increasing in volatile matter and fixed carbon of derived bio-char and the porous structure was observed in a range of macropore after pyrolysis. The TGA profile reveals CNS sample lost about 71.25% of mass before reached 750℃. The highest decomposition rate on the DTG profile was 0.57 mg/min and 0.56 mg/min as observed at about 261.2℃ and 340.3℃. Bio-oil yield has density of 1.036 gr/ml, viscosity of 19.5 cst after water removing, flash point of 138℃ and HHV of 21.7 MJ/kg. The GC-MS of the bio-oil shows about 53% phenol, 19% palmitic and oleic acid, 11% cyclobutene, 14% ethyl and methyl ester, and cyclopentene and cyclohexane in small amounts in accordance with FT-IR results.
