In this study, the effect of adding nanosize additive to glass fiber reinforced composite plates on mechanical properties and surface milling was investigated. In the light of the investigations, with the addition of MWCNTs additive in the composite production, the strength of the material has been changed and the more durable composite materials have been obtained. Slots were opened with different cutting speed and feed rate parameters to the composite layers. Surface roughness of the composite layers and slot size were examined and also abrasions of cutting tools used in cutting process were determined. It was observed that the addition of nanoparticles to the laminated glass fiber composite materials played an effective role in the strength of the material and caused cutting tool wear.

Advanced continuous polymer matrix composite materials provide considerable increase in flexural property values as compared with their bulk and monolithic counter parts. In this research work the effect of fiber orientation on the flexural strength of epoxy matrix composite materials reinforced with glass fiber was studied. Filament winding technique was employed for fabrication of composite with various fiber orientations. The flexural strength value of the glass fiber reinforced composite was comprehensively studied by means of three point bending flexural test and analysed by scanning electron microscopy. Experiments were conducted as per ASTM standards and it was concluded that reinforcement with 0o orientation of glass fibers shown improved flexural strength as compared to 45o and 90o orientation of fibers.

AbstractGlass-fiber-reinforced composite materials (GFRPs) are used widely in various fields of engineering. Turning is the principal process conducted on these materials for obtaining minimum surface roughness. Machining of GFRP materials is different from traditional style due to their inhomogeneous and anisotropic structures. Optimum machining parameters for specific GFRP materials need to be ascertained for perfect machining. In this study, the influence of cutting parameters and insert radius on the cutting force and surface roughness of GFRP material during machining was investigated. For measuring main cutting force, a three-component piezoelectric crystal type of dynamometer was used. Cutting force and surface roughness were experimentally measured through longitudinal axes of the GFRP material. Through this study, it was observed that high cutting speeds and low feed rates provide the best surface quality in the turning process of GFRP composite materials.
