“…The cellulose chains would better repack after the alkali treatment. Similar results have been reported elsewhere [32,33]. The treatment with silane leads to a decline in I c of MS, when compared to that of the alkali treated MS.…”

In this work Macadamia nutshell (MS) was used as filler in fused deposition modeling (FDM) of Poly (lactic acid) (PLA) composites filaments. Composites containing MS both treated and untreated with alkali and silane were investigated by means of Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD), Thermogravimetry (TG), scanning electron microscopy (SEM). The results showed that the treated MS composites had better thermal stability. Furthermore, compression tests were carried out. The PLA with 10 wt% treated MS composite was found possessing the best mechanical properties which was almost equivalent to that of the pure PLA. Finally, porous scaffolds of PLA/10 wt% treated MS were fabricated. The scaffolds exhibited various porosities in range of 30–65%, interconnected holes in size of 0.3–0.5 mm, micro pores with dimension of 0.1–1 μm and 37.92–244.46 MPa of elastic modulus. Those values indicated that the FDM of PLA/MS composites have the potential to be used as weight lighter and structural parts.

“…All composites presented two stages: a first stage with a slight weight loss in the range of 30-180 C due to the release of humidity retained in the fiber component of these composites and a second stage, which occurs between 215 and 450 C due to the pyrolysis process. 12,22,28,29 Figure 2(b) indicates that the alkaline treatment for jute + sisal composite was the least stable and this can be explained by the exposure time of the composite to the treatment. The final process is around 480-600 C which produced a reactive coal residue.…”

“…Similar results were reported in the literature. 12,22,28,29 reported that for the sisal fiber the alkaline treatment needs a longer exposure time than the other fibers because it has a larger diameter. The mixed treatment presented the expected behavior, which is the improvement of thermal stability in this kind of composite, as the coupling agent created a barrier around the fiber.…”

[19][20][21] Zafar et al 22 analyzed the chemical alkalization treatment and the mixed treatment (NaOH + Silane) of jute composite. Mixed treatment proved to be more efficient in increasing interfacial adhesion and thermal stability of the composites, but alkaline treatment improved the crystallinity index of jute fibers when compared to both untreated fibers and those that underwent mixed treatment.…”

The main objective of this work is to study the effect of chemical treatment on the thermal properties of hybrid natural fiber-reinforced composites (NFRCs). Different chemical treatments [i.e., alkalized and mixed (alkalized+ silanized)] were used to improve the adhesion between the natural fibers (jute, ramie, sisal, and curauá) and the polymer matrix. A differential scanning calorimetry, thermogravimetry, and a dynamic mechanical analysis were performed to study the thermal properties of hybrid NFRC. It was found that the chemical treatments increased the thermal stability of the composites. Scanning electron microscopy images showed that the chemical treatments altered the morphology of the natural fibers. A rougher surface was observed in case of alkali treated fiber, whereas a thin coating layer was formed on the fiber surface during the mixed treatment. However, for some fibers (i.e., sisal and rami), the chemical treatment has a positive impact on the composite properties, whereas for the jute and curauá composites, the best behavior was found for untreated fibers.
