Thermal properties of biocomposites based on sea mango fibers
No full textAccess is limited to UniMAP community.The effect of sea mango (SM) filler loading and the effect of amount used of polypropylene-graft-maleic anhydride (PP-g-MA) added as a compatibilizer on thermal properties and flow behavior of biocomposites were studied. The compounding of
polypropylene/sea mango biocomposites was carried out using different in weight
percentage of sea mango filler based on composite and different weight percentage of PPg-
MA based on weight of polypropylene (PP). Polypropylene/sea mango filler
biocomposites were compounded using a heated two roll mills at 165 °C and rolls rotating
speed of 10 rpm for 15 minutes. Then mixed samples were then compressed by using a
hydraulic hot press to form sheet samples of biocomposites at 1 mm of the thickness. The
result shows the effect of increment in filler loading were slightly increased in degradation
temperature, and slightly decreased in thermal stability, melting temperature, crystalline
temperature and percentage of crystallinity, and reduction melt flow index. It was also
found that the addition of PP-g-MA offer better processability and flow properties in
polypropylene/sea mango filler with PP-g-MA biocomposites than polypropylene/sea
mango biocomposites without PP-g-MA
The durability of modified silica/polypropylene nanocomposites : weathering resistance and creep behavior
No full textMaster of Science (Material Engineering)In this research, the modified silica (SiO2)/polypropylene (PP) nanocomposites were prepared. The accelerated weathering and creep behavior of nanocomposites were investigated. Neat PP with 2 wt% of nanosilica and 3 wt% of modifiers (aminopropyl triethoxysilane (APTES), polypropylene grafted maleic anhydride (PP-g-MA) and polypropylene-methyl polyhedral oligomeric silsesquixone (PP-POSS)) were melt blended in the internal mixer Brabender with rotor speed 60 rpm for 10 minutes. The nanocomposites characterizations were determined by Fourier transform infrared analysis (FTIR) and field emission scanning electron microscope (FESEM). While the mechanical properties of the nanocomposites were determined using a tensile test instrument according to ASTM D638 and thermal behavior through thermalgravimetric analysis (TGA) and differential scanning calorimetry (DSC), respectively, before and after exposure to accelerated weathering test (AWT). The durability behavior of nanocomposites was tested under creep test instrument according to ASTM D2990. From the FTIR analysis, weathered nanocomposites with the PP-POSS showed less carbonyl group which related to the degradation phenomenon to the material comparing to the nanocomposites with APTES, PP-g-MA and without modifiers. Moreover, FESEM images showed less cracking and deformation on the tensile fractured surface of weathered nanocomposites with PP-POSS validating the efficiency of the modifiers. While, from tensile results, the weathered nanocomposites especially with the presence of PP-POSS followed by PP-g-MA and APTES have higher tensile strength but moderate reduction in elongation at break than the weathered nanocomposites without the modifiers. In the terms of thermal behavior, PP-POSS showed good thermal stability compared to other nanocomposites. While for the durability test, the presence of modifiers in the modified silica/PP nanocomposites exhibited good resistance to the creep. PP-POSS provided better improvement creep resistance compared to the nanocomposites with PP-g-MA, APTES and without modifier. This can be concluded that the addition of modifiers improved the weather resistance and creep resistance of nanocomposites
Tensile and thermal properties of tapioca starch/sugarcane bagasse cellulose biocomposite films
No full textAccess is limited to UniMAP community.Cellulose was extracted from raw sugarcane bagasse (SCB) through chemical
route such as alkaline treatment and bleaching process. Cellulose obtained was
characterized and compared by Fourier transform infrared (FTIR) spectroscopy, X-ray
diffraction (XRD), scanning electron microscopy (SEM), and thermogravimetric
analysis (TGA). FTIR results show the reducing peak that related to non-cellulosic
components after chemical treatment. XRD analysis showed that cellulose has higher
crystallinity compared to raw SCB. SEM images illustrated the reducing in diameter of
fibre and increasing of roughness after undergoing chemical treatment. TGA analysis
revealed that cellulose has better thermal stability than raw SCB. The composite film of
tapioca starch and cellulose had been characterized and tested by XRD, SEM, TGA, and
tensile testing. XRD results show that composite with 5 phr cellulose has highest
intensity and crystallinity. SEM images of tensile surface fracture proved the good
interaction between filler and matrix for 5 phr cellulose content composite. TGA results
show neat starch film has highest thermal stability while tensile testing revealed
composite with 5 phr cellulose have the highest tensile strength and modulus of
elasticity
