“…There are many studies toward hybridizations which are numerous to mention. But few amongst them include oil palm and glass fibre-reinforced epoxy composite [13], jute-glass-and kenaf-glass-reinforced polyester [14], sisaland glass-reinforced epoxy [15], and flax/glass-reinforced polyurethane polyester [16]. In all the research highlighted, the researchers manipulate the constituents of these composites and allow materials with balanced static and dynamic strength to be synthesized and used in structural or semistructural applications.…”

In recent years, the hybrid composites of cellulosic and synthetic fibres are tailored to yield materials with reduced cost and weight. Prior to the fabrication of the hybrid composite, in most case, the cellulosic fibre needs surface modification for proper bonding. Therefore, this study investigates the effect of sodium bicarbonate treatment on the physical and mechanical properties of the hybrid and nonhybrid laminate composites of sugar palm and glass fibre-reinforced polypropylene. The findings will be compared with the conventional alkali treatment. The laminate composites were fabricated using the film stacking technique and hot compression process. Prior to the fabrication process, the sugar palm fibre in it which is naturally woven mat was treated with 4 wt% and 10 wt% alkali and sodium bicarbonate, respectively. All the laminate composites were investigated by tensile, flexural, and impact test, water absorption, and morphological examination. The tensile strength increased with both alkaline and sodium bicarbonate treatments for the hybrid and nonhybrid composites. The increase was more pronounced with the alkaline-treated SPF composite (L03) which displayed the highest value of 61.75 MPa, while that of the sodium bicarbonate-treated SPF composite (L04) recorded 58.76 MPa against 53.01 MPa for the untreated SPF composite (L02). The same trend was observed for the flexural strength. In overall, the alkaline treatment yielded better performance in comparison with sodium bicarbonate treatment.

“…In addition, the authors analyzed that as the GF content increased, the pores present in the RPUF decreased, thus increasing its specific mass and, consequently, the mechanical strength. A reference value of a virgin fiber glass/PU composite can be taken in work of Pandey et al, 30 that found values of specific flexural strength between 10 MPa/ (g.cm 3 ) and 63 MPa/(g.cm 3 ), and in this research was obtained a value of 29.25 MPa/(g.cm 3 ). The difference in work of Pandey lies in the direct consolidation of the PU resin within the fibers, which may improve the surface contact between fiber and resin.…”

The use of polymers in the automotive industry has been growing significantly, the recycling of these materials is a major challenge nowadays, since most polymer parts comprises of different types of polymers, and they are joined by chemical adhesives due to their lack of good compatibility. This characteristic hampers the recycling of such polymers, and makes separation economically unfeasible, as a consequence, their final destination has ended up in landfills. In this sense, the present research developed a technique to verify the recyclability of the manufacturing waste polymer auto parts from industry processes, through the polymer layup process to obtain a composite (fiberglass, polyester fiber, polyurethane) in the form of flat panel. To achieve the objectives, the polymers were individually analyzed by differential scanning calorimetry to assist in the definition of the overlap of joined polymers, in which differentiates from the conventional method of polymer blend by extrusion. The preformed polymer was consolidated by a hot press. The polymer composites were evaluated by three-point bending test and their structure was analyzed using scanning electron microscopy (SEM). The results in flexural properties indicate a suitable consolidation strategy when compared with results in literature, which is explained by the presence of glass fiber and PET in the final composition. Through the SEM images, it enabled to observe a good interface between the glass fiber and the polyester-based polymer matrix of the wastes, directly influencing the mechanical results of the material.

“…However, these methods are not suitable for engineering applications due to their high cost and complex processes. The strength of PU can be improved by adding inorganic rigid fillers such as glass fiber and montmorillonite, but the light transmittance and toughness will be sacrificed. − Therefore, the hydrogen bonding degree, crystallinity, and microphase separation degree play important roles in the adjustment of PU properties.…”

In recent years, aliphatic polyurethane has attracted more and more attention depending on its high adhesion and excellent optical and yellowing resistance properties. Among them, polyurethane-based laminated safety glass relies on the high strength of polyurethane films. In this work, the tensile strength of polyurethane film based on isophorone diisocyanate (IPDI) was increased from 48 to 65 MPa and the elongation at break was increased from 345% to 446% after solvent annealing. The absorbed impact energy of their laminated glass has been increased from 0.49 to 3.43 J, which is attributed to the activation of polyurethane chain segments rearranging by ethanol molecules. The higher hydrogen bonding degree and the regular internal structure are confirmed by FT-IR, SEM, and DMA characterization. On this basis, laminated glass with a high impact strength of Y12 film was successfully constructed.
