Polylactic acid (PLA) biocomposites reinforced with coir fibres: Evaluation of mechanical performance and multifunctional properties

Abstract

The effects of fibre content (5-30 wt%) and fibre treatment on surface morphology, tensile, flexural, thermal and biodegradable properties of polylactic acid (PLA)/coir fibre biocomposites were evaluated via scanning electron microscopy (SEM), mechanical testing, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and soil burial

Polylactic acid (PLA)/halloysite nanotube (HNT) composite mats: Influence of HNT content and modification

“…can be determined by the best-fitting of experimental data based on the least square method [32][33][34][35]. v f is the volume fraction of fillers and is a shape factor in relation to filler geometry and loading direction.…”

A Review on Biodegradable Polymeric Materials Striving Towards the Attainment of Green Environment

“…Improved fiber-matrix interfacial interaction of the surface modified tensile fractured samples was observed through SEM images. Wang L et al (2013) [80] adopted twin-screw extrusion process to prepare PLA and three types of sugarcane [82] analyzed the effects of fibre content and fibre treatment on the surface morphology, tensile, flexural, thermal and biodegradable properties of PLA/coir fibre biocomposites. SEM, DSC, TGA and soil burial tests were performed to confirm the same.…”

“…The concentration of fibers mass content varied from 10 to 30% for the composites and their mechanical properties were studied, whereas 25% fiber loading showed maximum improvement in tensile strength, tensile modulus, flexural strength and flexural modulus compared to neat resin. The composites with 5% sodium hydroxide treated fibers displayed higher interfacial shear strength and mechanical properties at room temperature compared to raw fiber composites.YuDong et al (2014) …”

Filling behavior, morphology evolution and crystallization behavior of microinjection molded poly(lactic acid)/hydroxyapatite nanocomposites

“…In the contemporary society, the biodegradable polymer materials [7][8][9], including natural polymer based materials (such as natural cellulose fibers [10][11][12][13][14], lignin [15], starch [16] and protein [17]) and synthetic polymers (such as poly(lactic acid) (PLA), polyhydroxyalkanoate (PHA) and poly(butylene succinate) (PBS)) [18][19][20][21], are attracting the increasing attention of both academic world and industrial world due to their benign properties such as biodegradability, environmental friendliness and acceptable physical-mechanical performance. Among the synthetic biodegradable polymer materials, poly(lactic acid) (PLA) could be believed as the most famous one.…”
