“…Facing the increasing environment problems and energy crisis, material scientists have raised great attentions and interests on natural fiber reinforced polymer composites (NFRC), such as bamboo fiber/high density polyethylene [1], wood fiber/Poly(vinyl chloride) [2], Banana/Sisal FiberPoly Lactic Acid Hybrid Composites [3], plant fiber/epoxy green composites [4], Plant fiber reinforced LDPE foamed composites [5], etc. These natural fibers applied above due to its co-friendly and sustainable advantages could substitute the synthetic fibers that dominated in the market currently [6].…”

Understanding the effect of moisture absorption on the mechanical properties of fibers at cellular level is key important to the application of natural fibers in reinforcement composites. This study focused on the variation of the modulus of elasticity (MOE) of several representative individual cellulosic fibers (bamboo, Chinese fir, ramie and Kevlar) under different relative humidity condition (RH: 40 %, 70 %, 90 %), dedicating for the screening of appropriate candidates of fibers used in outdoors. A special custom-designed microtester (SF-I) with the micro humidity control box was devised in order to observe stress-strain behavior of fibers under different humidity condition. Among the fibers investigated, ramie fiber presented the most sensitive to the humidity, Chinese fir and bamboo fiber was followed, and Kevlar fiber showed the bluntest to moisture variation since it belonged to artificial fiber. Compared with the fibers tested at RH of 40 %, the MOE of Bamboo, Chinese fir, Ramie fibers increased at RH 70 %, and decreased at RH 90 %, respectively. The optimal tensile properties were observed for the bamboo fiber among tested single plant fibers, with a MOE value of 26.3-30.7 GPa, and RH of 70-80 % was deduced for obtaining the highest value of MOE under various humidity testing condition.

“…The degree of crystallinity was calculated based on the following Eq .

X_{normalc} (%) = \frac{Δ H_{normalm}}{f \cdot Δ H_{normalm}^{normalo}} \times 100

where

Δ H_{normalm}

is the heat of melting (J/g) of test specimen and

Δ H_{normalm}^{normalo}

is the heat of melting for 100% crystalline PLA taken as 93.1 J/g and

f

as weight fraction of PLA from the literature .The DSC scans of virgin PLA (extruded and injection molded), UT‐BSF/PLA and BP‐T‐BSF/PLA hybrid biocomposites are illustrated respectively in Fig. .…”

“…This clearly indicates the superior compatibility and effective dispersion of BSF throughout PLA matrix as a consequence of IM process. This could be one of the possible reasons why an improved thermal stability was imparted by BP‐T‐BSF/PLA composites than virgin PLA and UT‐BSF/PLA composites .…”

“…Lastly, acetic acid was added to the BP treated BF to adjust the pH once again. The fibers were dried at room temperature for 2 days, followed by a vacuum oven drying at 80 °C for 24 h. PLA was dried for overnight in an oven at 50 °C and stored in an air tight bag as per the reported procedure . The surface modification of SF using NaOH followed by BP was carried out in a similar procedure followed for BF.…”

The present work focused on thermal behavior of biocomposites based on poly(lactic acid) (PLA) reinforced with untreated and benzoyl peroxide (BP) treated banana/sisal fibers (BSF) combination. Fabrication of biocomposites was performed by extrusion followed by injection molding. Fourier transformed infrared (FTIR) spectral technique ascertained the nature of bonding between BSF and PLA. The thermal properties of virgin PLA, UT‐BSF/PLA, and BP‐T‐BSF/PLA composites were studied by DSC and TGA analysis. DSC analysis indicated no significant changes in the glass transition temperature (Tg) and melting temperature (Tm) of virgin PLA, UT‐BSF/PLA, and BP‐T‐BSF/PLA composites and no sign of crystallization for both virgin PLA, UT‐BSF/PLA composites. However, crystallization was observed in BP‐T‐BSF/PLA composites. The BP‐T‐BSF/PLA composite exhibited a delayed thermal degradation pattern from TGA analysis when compared to that of UT‐BSF/PLA composites and virgin PLA as well. Further, the effect of BSF treatment and hybridization of BSF with PLA on the degree of crystallinity (Xc) were explored in detail. The above said composites were also investigated through scanning electron microscope (SEM) micrographs to examine the adhesion between the PLA and BSF. In addition, the results of SEM acquired are in good agreement with the data resulted from FTIR and thermal characterization. POLYM. COMPOS., 38:1053–1062, 2017. © 2015 Society of Plastics Engineers
