We present an easy and effective way to improve the mechanical properties of an epoxy matrix by reinforcing it with a combination of graphene oxide (GO) and reduced graphene oxide (RGO). These nanocomposites were prepared with different load of nanofillers: 0.1, 0.4, 0.7, 1.0 wt% and a neat epoxy. Ratios of graphene oxide and reduced graphene (GO : RGO) employed were: 0 : 1, 0.25 : 0.75, 0.5 : 0.5, 0.75 : 0.25, and 1 : 0. Results show that with only 0.4 wt% and a ratio 0.2 : 0.75 of GO : RGO, tensile strength and tensile toughness are 52% and 152% higher than neat epoxy while modulus of elasticity was improved~20%. The obtained results suggest that it is possible achieve advantageous properties by combining graphene in oxidized and reduced conditions as it shows a synergic effect by the presence of both nanofillers.

Manufacturing Applications

Development of epoxy with filled particles provides an avenue for manufacturing applications in the tooling industries especially in the mould and die industries. The performance of epoxy and fillers as mould materials is greatly dependant on the production quantity and process conditions. Metal and non-metal fillers such as copper, brass, graphite and silicon carbide are blended into the epoxy matrix, altering the mechanical properties, as well as thermal conductivity of the epoxy composite. This review presents the investigation on the effect of varying composition of metal and non-metal fillers on the mechanical properties of epoxy composite. Different mixing ratios are investigated ranging from 10%, 20%, 30% and 40%, based on the weight ratio of epoxy resin, hardener and filler material. Previous studies showed that increase in amount of filler increases the hardness and compression strength of epoxy matrix. Adversely, tensile strength shows a detrimental effect with the presence of fillers, whereby increase in metal fillers reduces the tensile strength with increased composition loading from 10% to 40% of weight. Wear rate was found to reduce with the presence of aluminum, alumina and silicon carbide, hence increasing the wear resistance of the epoxy composite.

An effective approach to the fabrication of progressive epoxy nanocomposites by the incorporation of hydroxyl-terminated dendrimers functionalized graphene oxide (GO-TCT-Tris) is reported. The relationship between surface grafting, chemical construction, morphology, dispersion, and interfacial interaction as well as the corresponding mechanical properties of the composites were studied in detail. It was shown that hydroxyl-terminated triazine derivatives have been resoundingly bonded onto the GO surface through covalent bonding, which effectively improved the dispersion and compatibility of GO sheets in epoxy resin. The tensile and flexural tests manifested that the GO-TCT-Tris/epoxy composites exhibited greater tensile/flexural strength and modulus than either the pure epoxy or the GO/epoxy composites. For GO-TCT-Tris (0.10 wt%)/epoxy composite, the tensile strength and elastic modulus increased from 63 ± 4 to 89 ± 6 MPa (41.27%) and from 2.8 ± 0.1 to 3.6 ± 0.2 GPa (28.57%), and the flexural strength and modulus increased from 106 ± 5 to 158 ± 6 MPa (49.06%) and from 3.0 ± 0.1 to 3.5 ± 0.2 GPa (16.67%), respectively, compared to the pure epoxy matrix. Moreover, the fractographic analysis also illustrated the ameliorative interfacial interaction between GO-TCT-Tris and epoxy matrix.

Abstract Polymeric particles composites with hard inorganic particles are abrasion resistant materials which can be used in the sphere of agriculture - e.g. for functional areas in renovation or as resistant layers. Silicon carbide waste particles were used in the present experiment, replacing the primary filler with waste without significant changes in the mechanical properties. The present paper describes the effect of immersion of polymeric particles composites with epoxy matrix in liquids on selected mechanical properties. Overall, it explains the change of hardness and resistance of abrasive wear, a typical kind of wear in the sphere of agriculture.

Epoxy resins have been presenting a lot of scientific and technical interests and organic modified epoxy resins have recently receiving a great deal of attention. For obtaining the composite materials with good mechanical proprieties, a large variety of organic modification agents were used. For this study gluten and gelatin had been used as modifying agents thinking that their dispersion inside the polymer could increase the polymer biocompatibility. Equal amounts of the proteins were milled together and the obtained compound was used to form 1 to 5% weight ratios organic agents modified epoxy materials. To highlight the effect of these proteins in epoxy matrix mechanical tests as three-point bending and compression were performed.
