“…This means that, although these components can be already detected, weaker, in the spectrum of pure PLA, the addition of sisal changes relative intensities. For instance, similar features were assigned to symmetric and asymmetric methyl and methylene groups of side chains likely in the lignin structure of sisal [ 37 , 38 ] which, in our case, will overlap with features typical of PLA chains leading to an increased relative absorption in this region. Correspondingly, the relative intensity of the band at 2997 cm −1 (v as CH 3 ) slightly decreases (although not proportionally) in samples PLA20 and PLA30, if compared to other bands in this region (i.e., bands at 2922 and 2850 cm −1 ).…”

A series of poly(lactic acid) (PLA) and poly(lactic acid)-based bio-composites (sisal PLA) were prepared and studied by spectroscopic and microscopic techniques as such and after immersion at room temperature in different degradation mediums (i.e., distilled and natural sea water and solutions at pH = 2, 6, and 8). In these conditions, some of their macroscopic and microscopic properties were monitored during a period of 30 days. Water absorption increased with the increasing fiber content regardless of the immersion medium. The maximum water absorption was achieved at pH = 8 (~16%), indicating a more severe action of the alkaline mediums on the samples. The diffusivity, D, of PLA decreased with the addition of fibers and acidic mediums showed higher D, indicating higher diffusivity of water through the specimens with respect to those submerged in moderate or alkaline mediums. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) analysis evidenced a weak interaction between the PLA matrix and the sisal fibers. Very limited degradation phenomena occur in our conditions: Despite some changes in the microstructure, the PLA backbone seems to be largely resistant to hydrolysis, almost regardless of the pH value and even at the highest sisal content.

“…Samouh et al [170] reported that the introduction of sisal fiber to PLA matrix not only enhances the strength but also the impact property of sisal fiber/ PLA composite. Sisal fiber/PLA fiber with 15% sisal fiber content exhibit 30.30% of enhancement in Charpy impact strength, which is comparable to other reported works [171,172].…”

In recent years, researchers across the globe have switched from synthetic fibers to natural fibers for the fabrication of composites. The desirable properties of natural fibers which attracted researchers, as well as academicians, are its low density, easy availability, environmentally friendly nature, biodegradability, and high specific strength. Hence in the last decade, there is tremendous progress in the development of natural fiber-reinforced composites for various industrial applications. The current review focused on the recent progress in natural fiber-reinforced polymer composite. The natural fibers discussed in this review are derived from leaves, namely pineapple, sisal, and abaca. The extraction and processing of these fibers are briefly outlined. The properties and application of natural fiber-reinforced composites are also addressed in this review. One of the drawbacks of natural fiber is its poor compatibility with the polymer matrix. The different treatment methods to improve the fiber-matrix interaction are also summarized in the present review.

“…The sisal fiber cultivated in several African countries (precisely in Morocco) is exploited only in traditional medicine. The performance of Moroccan sisal fiber was investigated in a previous study by showing the important mechanical resistance of the Moroccan sisal fiber [41]. This work aims to show the potential of sisal fiber of Moroccan origin for the reinforcement of composite materials at the fiber and yarn scale.…”

This work aims to investigate the physical and mechanical properties of sisal fiber and yarn of Moroccan origin. The cellulosic and non-cellulosic constituents of the Moroccan sisal fiber were identified by FTIR spectroscopy. The thermal properties were studied by thermogravimetric analysis. The hydrophilicity of the fiber was evaluated by the contact angle. The results show that the sisal fiber has a low thermal stability. The mechanical properties of the fiber analyzed by the Impregnated Fiber Bundle Test (IFBT) method show that the porosity of the impregnated yarns and the twist angle of the yarns influence the elastic modulus of the sisal fiber. The physical and mechanical properties of the manufactured sisal yarns were also characterized and analyzed. The obtained results reveal an interesting potential to use the Moroccan sisal fiber in development of bio-sourced composite materials.
