“…The HIPS curves showed a single stage of mass loss at approximately 444.88 °C, which is also the level observed in the works of Cordeiro et al [37] and Agung et al [38] ; in this case 415 °C. The curves of the composites showed that the addition of the residue provided a slight increase in the temperature at the beginning of degradation of the M2.5 composite, i.e., 444.68 °C (Figure 6c), but for the M5 composite this temperature dropped to 275.94 °C (Figure 6d).…”

“…Figure 7 also shows the specific heat (Cp) reduction for composites. This behavior was caused by the shells, which reduced heat transfer [38] . The shells of Brazil nuts consist of the exotesta regions, central mesotesta region, mesotesta vascular region and tegmen that present structures with voids such as long and porous cells, porosities and vascular exchanges [41,42] .…”

Solid residues from agroindustry often accumulate and cause environmental imbalance. An alternative to this is to use this residue as a reinforcement in polymers. The achievement of this work was to characterize a composite with a polystyrene matrix reinforced with Brazil nut shells residues. The residues were cleaned and ground to then produce the samples via injection molding with the proportions of 0%, 2.5% and 5% of load. The specimens were characterized using mechanical tensile testing and thermogravimetric analysis (TGA). The mechanical test showed that the composite with 2.5% of filler had greater stiffness and strength was improved by 5%. Thermal analysis showed an increase in the temperature for the beginning of the degradation of the M2.5 composite. The results confirm a potential application in the automotive industry for the polystyrene composite reinforced with Brazil nut shells.

“…DCS was carried out to determine the thermal behaviour of the fibers. DSC analysis also enables the identification to be made of chemical activity occurring in the fibers as the temperature is increased (Agung et al 2011). Figure 4a shows the DSC curve for raw kenaf bast fiber.…”

Cellulose nanocrystals (CNC) were prepared from delignified kenaf bast fiber by using alkaline pulping, based on soda anthraquinone, hydrogen peroxide bleaching, and acid hydrolysis treatment with H2SO4. The size and morphology of the fibers were characterized by scanning electron microscopy (SEM), and the isolated fiber from unbleached and bleached pulp had a diameter between 9 to 30 µm. Fourier transform infrared (FTIR) spectroscopy exhibited that the content of lignin decreased in the pulping process, and the lignin was almost completely removed during hydrogen peroxide bleaching. Moreover, fibers were characterized for crystallinity using X-ray diffraction (XRD). The fiber crystallinity gradually increased at each stage of the process (raw kenaf bast, unbleached pulp, bleached pulp, and acid hydrolysis). The fiber was characterized by atomic force microscopy (AFM), which showed that the isolated pulp nanofibers had diameters of approximately 30 nm.

Differential scanning calorimetry (DSC) was used to study the thermal behaviour of abaca fibre reinforced high impact polystyrene (HIPS) composites. Thermal analysis is based upon the detection of changes in the heat content (enthalpy) and the glass transition temperature (Tg) of optimum condition of abaca fibre reinforced HIPS composites. In this research, glass transitions temperature (Tg) of neat HIPS occurred below the Tg of optimum condition of composites as the temperature of an amorphous state. The endothermic peak of composites was in to range 430-435°C including neat HIPS and it observed that enthalpy of abaca fibre reinforced HIPS composites yielded below the neat HIPS 748.79 J/g.
