“…Epoxy resin as a matrix for the development of such composites has gained popularity due to its adhesion to various fillers, electrical resistance, low density, and good mechanical properties 3–6 . However, the use of epoxy resins for composite development has suffered some shortcomings in recent times, such as their requirement for hardeners or curing agents, smoke suppressants, and flame retardants in the fabrication of composites, which have elevated their cost of production 7–9 . In this regard, various researchers have gone out of their way to seek suitable alternatives with better quality and lower cost compared to epoxy resin‐based composites 10 .…”

The advantages that plastic‐based composites provide over epoxy‐based composites have catalyzed interest in the former in recent years. Polystyrene, a common packaging plastic, has been used for the production of composites. However, its hydrophilicity and curing duration are issues that undermine its commercialization. In this study, two fillers, calcined cow bone and kaolin, were introduced into a polystyrene resin matrix in varying concentrations through the hand lay‐up method. The composites were thermally cured at a temperature of 200°C for 3 h, after which they were characterized for their thermal and microstructural properties. DSC analysis revealed that the presence of kaolin improved the thermal property of the composite more than cow bone. The FTIR results revealed that the filler(s) were incorporated into the matrix via chemical reactions, as evidenced by bond breakage and formation. EDX results confirmed the incorporation of the fillers, with carbon being the most dominant element in the composites. It showed that the cow bone introduced elements such as phosphorus and calcium, while the kaolin introduced elements such as silicon and aluminum to the composite. SEM micrographs showed the presence of good interfacial adhesion between the filler(s) and the matrix. This study has shown that thermal curing is a viable solution to the shortcomings of polystyrene‐based composites and their commercialization.

“…At the same time, the residues of the solvent are highly likely to negatively affect the functional characteristics of the resin. [21][22][23][24] Another approach that has been adopted is particulate toughening using core-shell rubber particles, rubber particles, and inorganic silicates. [25][26][27][28] Several recent studies have also considered various nanoparticles, such as carbon nanotubes and inorganic silicates.…”

This study demonstrated that the addition of dissolvable polyether sulfone fibers to the interlaminar area of carbon fiber/epoxy composites can effectively increase the toughness with very high accuracy. Resin film infusion (RFI) is used to fabricate composite structures. RFI was applied to obtain polyether sulfone as an interleaf of chopped fibers between fabric piles of carbon fibers. The thermoplastic polyether sulfone fiber dissolved in the epoxy when it was cured at a high temperature. A phase-separated morphology with a polyether sulfone-rich secondary phase was formed during the curing process. Experimental results indicated that G Ic, which is the average value of Mode-I fracture toughness, was increased fivefold with the addition of 10 wt% polyether sulfone fiber (with respect to the gross content of the matrix). No detrimental effects were observed in other characteristics such as thermal stability, Young’s modulus, and tensile strength. In addition, the thermal and mechanical characteristics of neat epoxy–polyether sulfone blends were analyzed for comparison.
