“…Apparently, the neat polyester displays a major DTG peak at 385 1C and a tail peak around 415 1C. The authors [52] attributed these polyester thermal degradation events to the evolution of volatile compounds followed by depolymerization of macromolecular chains, quoting Mark et al [53]. Similar curves are observed in Fig.…”

“…Santafé Jr. et al [52] characterized the thermogravimetric behavior of untreated coir fiber incorporated in different composition (up to 30 vol%) into polyester matrix composites. TG/DTG curves were obtained at a heating rate of 10 1C/min in nitrogen.…”

“…Apparently, the onset of thermogravimetric degradation in a natural fiber composite is a complex process, which depends not only on the comparative thermal stability of fiber vs. matrix but also on the experiment atmosphere. In petroleum-based polymers that are traditionally used as engineering materials and possess a high degree of biodegradability resistance (non-degradable), such as high density polyethylene [36], epoxy [48], polyester [52], and polyurethane [69], a single DTG peak under nitrogen is observed at relatively higher temperatures: 515, 380, 385, and 420 1C, respectively. Comparative decrease may occur in air [37].…”

“…Thermal stability of the composite increases with the increased fibre loading, which was clearly seen from the percentage of the residue or ash of the various composites. The findings of the thermal analysis of SPF-reinforced polymer is supported by the work of Santafé et al (2011). They reported that the TG curves of untreated coir reinforced polyester composite at different fibre loading (10, 20, and 30 wt.%) showed an onset of degradation at approximately 340 °C and completed at 450 °C.…”

The use of natural fibres as reinforcement in composite materials has increased over the years due to the rapid demand for renewable, costeffective, and eco-friendly materials in many applications. The most common and adopted natural fibres used as reinforcements are flax, kenaf, hemp, jute, coir, sisal, and abaca. However, sugar palm fibre (SPF) as one of the natural fibres is gaining acceptance as a reinforcement in composites, though it has been known for decades in the rural communities for its multipurpose traditional uses. Sugar palm fibre (SPF) is extracted from sugar palm tree typically from its four morphological parts, namely, trunk, bunch, frond, and the surface of the trunk, which is known as Ijuk. In this paper, sugar palm tree, its fibre and composites, and biopolymers derived from its starch are discussed. Major challenges and the way forward for the use of sugar palm fibre and its composites are highlighted. This review also opens areas for further research on sugar palm fibre and its composites for academia and industries.

In recent years, the growth of environmental awareness has increased the interest in the development of biocomposites which are sustainable materials with an excellent price–performance ratio and low weight. The current study aimed to obtain and characterize the biocomposites prepared by thermoforming using coir fibres as reinforcing material and polypropylene as matrix. The biocomposites were produced with different coir fibres/polypropylene ratios and were characterized by physical–mechanical indices, thermal analysis, crystallinity, attenuated total reflection-Fourier transform infrared spectroscopy analysis (ATR-FTIR), scanning electron microscopy (SEM), and chromatic measurements. Both tensile and bending strength of biocomposites decreased when the coir fibre content increased. The melting temperature of biocomposite materials has decreased with the increase of the coir fibre loading. Regarding the thermal stability, the weight loss and degradation temperature increased with decreasing coir fibre content. The ATR-FTIR and SEM analyses underlined the modifications that took place in the structure of the biocomposites by modifying the coir fibres/matrix ratio.
