“…Thermogravimetric analysis (TGA) is extensively utilized to investigate the thermal degradation of polymeric composites, when the composite specimen is subjected to higher thermal loading [22]. The thermal stability of a material describes its ability to resist mechanical deformation at higher temperature [23]. Many researchers investigated the thermal stability of hybrid synthetic/natural fiber reinforced polymeric composites by using thermogravimetric analysis.…”

The aim of the present research work is to enhance the thermal and dynamic mechanical properties of Kevlar/Cocos nucifera sheath (CS)/epoxy composites with graphene nano platelets (GNP). Laminates were fabricated through the hand lay-up method followed by hot pressing. GNP at different wt.% (0.25, 0.5, and 0.75) were incorporated with epoxy resin through ultra-sonication. Kevlar/CS composites with different weight ratios (100/0, 75/25, 50/50, 25/75, 0/100) were fabricated while maintaining a fiber/matrix weight ratio at 45/55. Thermal degradation and viscoelastic properties were evaluated using thermogravimetric analysys (TGA), differential scanning calorimetric (DSC) analysis, and a dynamic mechanical analyser (DMA). The obtained results revealed that Kevlar/CS (25/75) hybrid composites at 0.75 wt.% of GNP exhibited similar thermal stability compared to Kevlar/epoxy (100/0) composites at 0 wt.% of GNP. It has been corroborated with DSC observation that GNP act as a thermal barrier. However, DMA results showed that the Kevlar/CS (50/50) hybrid composites at 0.75 wt.% of GNP exhibited almost equal viscoelastic properties compared to Kevlar/epoxy (100/0) composites at 0 wt.% GNP due to effective crosslinking, which improves the stress transfer rate. Hence, this research proved that Kevlar can be efficiently (50%) replaced with CS at an optimal GNP loading for structural applications.

“…The effects of the bi-functionalized MMT on the morphological, thermal stability, dynamic, mechanical, and tensile properties of the epoxy/OMMT nanocomposites were studied. As part of our previous work [22][23][24], the data obtained from this work can be utilized to produce a high-performance natural fiber/nanoclay/epoxy hybrid nanocomposite which could potentially be used for automotive or building and construction applications.…”

In this work, the optimum filler loading to prepare epoxy/organoclay nanocomposites by the in-situ polymerization method was studied. Bi-functionalized montmorillonite at different filler loading (0.5, 1.0, 2.0, 4.0 wt %) was dispersed in epoxy resin by using a high shear speed homogenizer. The effect on morphology, thermal, dynamic mechanical, and tensile properties of the epoxy/organoclay nanocomposites were studied in this work. Wide-angle X-ray scattering (WAXS) and field emission scanning electron microscope (FESEM) studies revealed that possible intercalated structures were obtained in epoxy/organoclay nanocomposites. Thermogravimetric analysis (TGA) shows that epoxy/organoclay nanocomposites exhibit higher thermal stability at the maximum and final decomposition temperature, as well as higher char content, compared to pristine epoxy. The dynamic mechanical analysis (DMA) indicate that storage modulus (E′), loss modulus (E″), cross-link density and glass transition temperature (Tg) of the nanocomposites were improved with organoclay loading up to 1 wt %. Beyond this loading limit, the deterioration of properties was observed. A similar trend was also observed on tensile strength and modulus. We concluded from this study that organoclay loading up to 1 wt % is suitable for further study to fabricate hybrid nanocomposites for various applications.

Banana fiber has potential to be utilized in bio-based composite structures due to its low price, abundantly available and biodegradability. However, the performance of this fiber is still not comparable to the synthetic polymeric system. In this work, the thermal stability analysis and tensile test of optimized banana fiber that was initially evaluated using response surface method were conducted. The thermal analysis and the tensile test were conducted using thermogravimetric analyzer and universal testing machine respectively. It was shown that the banana fiber content offered an outstanding performance in thermal stability. The highest thermal stability however, was found in neat epoxy resin system. The TG and DTG results showed the lowest amount of residue occurred in banana/epoxy composite. The tensile data properties revealed that banana composite is comparable to synthetic samples
