“…It is also noted in those same curves (Figure 1), two degradation peaks at around 290°C and 360°C, which temperatures cause the decomposition of cellulose and hemicellulose. Lignin remains in this temperature range because its decomposition generally starts from 370 ºC 43,44,45 . TGA analyzes were also performed to verify the thermal events of the analyzed fibers.…”

Biodegradable polymeric composites using natural fibers have been investigated aiming to mitigate environmental impacts. In this paper, polyhydroxybutyrate (PHB) composites obtained using random mats of sisal and coconut fibers by compression molding in a hydraulic press, and the fiber content varied between 10% and 15% relative to the weight of the polymer. Thermal analyses were performed such as Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). Flexural and tensile tests were performed before and after conditioning in climate chamber with temperature and moisture. The results of thermal analysis show that the thermal stability of the materials remained, both PHB without fiber as for composites with natural fibers mats. The results of mechanical tests indicated that the PHB without fibers and composites showed similar flexural strength values, while the results of the tensile test PHB without fibers showed resistance to higher tensile composite.

“…It will be such a waste if this plant is cut and being thrown away. When the natural filler is use as the reinforcement of the composite, there will be some disadvantages such as lignocellulosic fiber contain high level of moisture absorption, poor surface adhesion to hydrophobic polymer, low processing temperature permissible ad many more [4][5][6]. The main problem is because these filler have strong hydrophilic character, which make the interfacial adhesion between this type of filler and hydrophobic polymer matrix poor.…”

“…As the global energy crisis has increased in severity and ecological risks are more serious, plant fibers such as sisal [1], hemp [2], flax [3], jute [4], and kenaf [5] have become more attractive candidates to replace artificial fibers as reinforcement in polymers. Compared with conventional synthesis fibers, these plant fibers are abundant, renewable, biodegradable, inexpensive and lightweight [6].…”

ABSTRACT Environmental awareness and an increasing concern with sustainable development have stimulated many industries including ground engineering to replace the conventional synthetic fibers. In this work, flexural strength and flexural modulus of chemically treated random short sisal fiber reinforced polypropylene and unsaturated polyester composites were investigated over a range of fiber content. Flexural strength of the composites was found to decrease with increased fiber content; however, flexural modulus increased with increased fiber content. The reason for this decrease in flexural strength was found to be due to fiber defects which could induce stress concentration points in the composites during flexural test, accordingly flexural strength decreased. Alkali and silane fiber treatments were found to improve flexural strength and flexural modulus which could be due to enhanced fiber/matrix adhesion.
