Purpose The purpose of this paper is related with the comparative study between graphene-based glass fiber–reinforced polymer composites and without graphene composite on polymer matrix. The current study explains the result of amalgamation of 4 Wt.% graphene oxide (GO), in comparison to without graphene, on the mechanical strength of glass fiber/epoxy (GE). Design/methodology/approach A hand layup technique is used for the experimental study. For this, chemical synthesis process is approached based on Hummer’s theory. For mechanical testing of glass fiber–reinforced graphene composites and without graphene composites, American Society for Testing and Materials-3039 (ASTM3039) standards was adopted. Furthermore, comparatively, composites were characterized by field emission scanning electron microscopy. Findings Reinforcement of 4.0 Wt.% GO in epoxy matrix material showed 7.46% and 12.31% improvement in mechanical strength and elongation, respectively. Scanning electron microscopy results showed the influence of graphene cumulations in the failure of GO-reinforced GE (GO-GE) composites. Originality/value The inimitable things of graphene grounded nanofillers have encouraged in the world of material for their thinkable manipulation in glass fiber polymeric composites. In this work, for the first time, graphene is used as nanofiller in glass fiber epoxy coatings, and their fractography study is investigated.

Thermoplastic polyurethane elastomer (TPU) and long glass fiber (LGF) were used to prepare LGF/TPU master batch for increasing the mechanical properties and heat resistance of PVC. It turned out that addition of LGF/TPU contributed to improvement in toughness of PVC but the heat resistance of PVC didn’t increase very evidently. The heat resistance and morphology were observed by vicat test and scanning electron microscopy, respectively. The scanning electron microscopy (SEM) proved that incorporation of LGF/TPU into PVC changed the morphology of the composites and correlated well with the mechanical properties. Dynamic mechanical analysis (DMA) showed that both the glass transition temperature and the storage modulus of PVC increased with the addition of LGF/TPU master batch; the presence of a single Tg indicated that each component of composites was miscible. In this study, the combination properties of the composites with 24wt% LGF was the best proportion in the range of 0-30 phr LGF, because it had the best mechanical properties and heat resistance.

A two-continuous-phase sulfur–asphalt composite was developed for use as a road repair material. Two methods to obtain a continuous sulfur phase in a continuous asphalt phase are described. Scanning electron microscopy and mercury porosimetry technique provided evidence for a continuous sulfur phase. Mechanical properties—determined from hardness, uniaxial tension, and fracture energy measurements—of the two-continuous-phase sulfur–asphalt composite were studied at 22 and −31 °C. Mechanical properties of fiber-reinforced (up to 2% by volume of dacron fibers) sulfur–asphalt composites were also studied.

Adhesion and friction of E-glass fiber-reinforced epoxy (E-GFRE) composites were studied using pin-on-disc tester. The worn surfaces of the composites were examined using scanning electron microscope. The results showed that the wear resistance of E-GFRE composites can be improved by inserting approximately 5–10 wt% C-filler loading. Above 10 wt%, the wear mass loss increased linearly with increasing C-filler loading. The reinforcing C-filled E-GFRE composites have almost the same friction coefficient as the pure epoxy matrix which increased slightly on increasing C-filler loading. From the SEM microscopy observation, the main wear mechanisms for pure E-GFRE composites were plastic deformation, abrasive wear, and fatigue wear.

The effects of polypropylene grafted with maleic anhydride (PP-g-MA) on the interfacial interaction of PP/GF composites were investigated by means of scanning electron microscopy (SEM), dynamic mechanical analysis (DMA), and mechanical properties. The experimental results demonstrate that PP-g-MA could effectively improve interfacial interaction between the PP and LGF. Based on SEM, good interfacial adhesion between PP and LGF in PP/PP-g-MA/LGF（66.5/3.5/30） composites was observed. All results in this paper were consistent, and showed the good interaction between PP and LGF, which were proved by the mechanical properties of the composites.

This paper presents the effect of accelerated salt spray (fog) exposure on commercially glass fiber reinforced polyester composite to determine the durability of the material. Aging behavior after exposure in the salt-spray environment was studied by mechanical properties i.e. flexural stress and flexural modulus. The accelerated salt spray exposure was conducted by Copper-Accelerated Acetic Acid Salt Spray (CASS) Test according to ASTM B368. The CASS exposure was carried out for 120 hours and observed every 24 hours. The flexural modulus results tend to be constant up to 4 days and more significant change on 5th day of measurement. Furthermore, the morphology of specimens investigated by a Scanning Electron Microscopy (SEM). The SEM results also showed that only scratch occurred on the surface of the specimens test. The longer of the CASS exposure time, the higher the number of scratches. From this study, it could be concluded that Glass Fiber Reinforced Polyester Composite has slightly damage for 120 hours CASS test exposure.
