In this study, cellulose nanofibrils (CNFs) were modified by catalyzed lactic acid esterification in an aqueous medium with SnCl2 as a catalyst. Films made from unmodified and acid-modified CNF without polymer matrix to evaluate the effectiveness of modification. Ungrafted acid-grafted was also compounded poly(lactic acid) (PLA) produce composites. Mechanical, water absorption, barrier properties evaluated for ungrafted CNF, films, PLA/CNF composites ascertain effect modification on films...
Cement is considered a key raw material for brick production. However, excessive use of cement leads to negative environment impact. replaced with locally available waste materials has significant potential address this environmental impact, especially in the construction industry by contributing cleaner The objective research investigate performance where fly ash and palm oil fuel ash, typically Malaysia, on rise. To determine these bricks, compressive strength test, water absorption...
The effect of water and alkali treatment on the thermal decomposition oil palm shell (OPS) together with mechanical performance polyester composites reinforced treated OPS has been presented in this work. Treatment cold/hot distilled cold were found to improve tensile flexural strength resulting although highest was noted use sonication hot water. On other hand, produce a composite similar that sonication. FTIR tests indicated adsorbed molecules some parts hemicellulose lignin removed by...
The effect of alkali treatment and nanoclay addition on the mechanical properties water absorption behavior rice husk particle (RHP) reinforced unsaturated polyester (UP) composites was investigated. Thermogravimetric analysis (TGA) indicated that removed most hemicellulose impurities from RHP with tensile strength, modulus, flexural strength modulus resulting being improved by treatment. results 5% sodium hydroxide concentration had optimum performance resistance. Furthermore, influence (1,...
This paper presents a study on the effect of alkali treatment Oil Palm Kernel Shell (OPKS) mechanical properties ofpolyester composite. The dosage NaOH in this is limited to 5wt% concentration.The experiments investigate tensile strength, flexural strength and theflextural modulus untreated, cold treated hot OPKS reinforced polyester It found that improves However, improvement due tothe significant compared treatment. morphology fracture surface composites were investigated using scanning...
Bamboo fibers as a natural fiber offer numerous advantages such high specific strength over synthetic when used reinforcing for polymer composites. Yet the hydrophilic nature of bamboo with moisture absorption results in incompatibility between and unsaturated polyester resin. An experimental study was carried out to investigate effects alkali treatment on mechanical properties water sorption composite. The result revealed that, composite 5% Alkali treated possesses highest properties....
The aim of this paper is to investigate the effect chemical treatment on flexural properties composite. Oil Palm Empty Fruit Bunch Fibers (OPEFB) reinforced Vinylester composite were prepared in study. Soxhlet extraction together with sodium hypochlorite bleaching methods was used for treatment. diameter fibers reduced from a range 250-350 μm 10-15 by Shape and texture transformed solid brown colored strings into white gel. Thermogravimetric Analysis (TGA) test carried thermal natural...
This paper presents a study on tensile properties of Nano Silicon Carbide (n-SiC) and oil palm fibre (OPF) reinforced epoxy composites. The dosage n-SiC OPF are limited to 0%, 1%, 3% & 5% by mass the total material. As part research, experimental is carried out based composites investigate strength composite utilization 1% n-SiC& treated shows an improvement in compared pure epoxy. results also with 3-D finite element analysis good agreement observed between results.
