“…There is a need to enhance mechanical and impact properties of glass epoxy composites as it will enable realizing light weight structures for both civilian and defense applications [6]. One of the possibilities is to increase the interface compatibility of the epoxy and glass fiber [7,8]. For this purpose many researchers have explored the possibility of employing various additives like CNTs, CNFs, glass micro balloons, nanoclay etc.…”

Organically modified montimorillonite nanoclay was added to the epoxy and E-glass-epoxy composites. The influence of nanoclay content (varied between 0 to 5wt %) on the relative crosslink density and the fracture toughness of the epoxy matrix was studied. Differential scanning calorimetry (DSC) indicated that the amino functional groups present on the nanoclay react with the epoxy matrix to increase the crosslink density of about 13 and 18% at 3 and 5wt% addition, respectively. The toughness of the epoxy composites increased by 25% at 3wt% addition of nanoclay, whereas, it decreases at 5wt%. Flexural strength and tensile strength of the E-glass-epoxy composites were found to increase by 12% and 11% respectively at 3wt% addition of nanoclay, while at 5wt% addition these properties decreased due to the matrix embrittlement. Interestingly matrix embrittlement is found to be beneficial in increasing the impact resistance due to spallation of embrittled matrix that ensures the dissipation of the impact energy. 5wt% nanoclay addition increases the impact strength by 29% and reduces the back face bulge of composite by 31%. These results may lead to the design and realization of glass-epoxy composites with better impact strength.design and realization of glass-epoxy composites with better impact strength.

“…Several efforts have been made to improve this poor longitudinal compressive strength by embedding nano-enforcements on the surface of the ber. 35 The other method is to replace the pure resin polymer matrix with lled nano-particles. 36 In such conditions, plastic deformation induced by empty spaces absorbs the impact energy, resulting in high impact and compressive strength.…”

“…Material preparation begins with the filling of the epoxy resin (Marine 820 from Axson Technologies, Madison Heights, MI, USA) with graphene. Graphene concentration was fixed at 1 wt%, higher percentages have been found to deteriorate mechanical properties since the particles tend to agglomerate [24][25][26] and may also cause an increase of the resin viscosity, making the resin incompatible with the GFRP fabrication process. A commercially available graphene was used for this study (GrapheneBlack 0X) and supplied by NanoXplore Inc. (Montreal, QC, Canada).…”

Glass fiber reinforced polymers (GFRPs) are used extensively in many industries because of their low cost and high mechanical properties. Even if composite manufacturing processes are well controlled and allow to fabricate near net shapes, machining operations are still necessary to complete the manufacturing. As a composite material, GFRP machining remains difficult because of its heterogeneous and anisotropic character. This work intends to investigate the effect of graphene addition to the epoxy matrix of GFRP on its machinability. The epoxy was filled with 1 wt% graphene by mixing, sonicating, and then being used to produce unidirectional GFRP laminate by hand layup methods. Thermocouples were bonded on a chemical vapor deposition (CVD) diamond coated tool in order to record cutting temperatures during the trimming process. The cutting forces were recorded and the resulting surface roughness after trimming was measured to qualify properly the machinability of the modified GFRP. Compared to the reference material (GFRP without graphene), the additive improved the machining process by decreasing the cutting temperature and forces as well as the surface roughness without deteriorating the inter-laminar shear strength.
