Investigation of effect of stacking squence on the mechanical properties of hybrid composites

In this study effect of the stacking squence on mechanical properties of carbon-basalt reinforced composites are investigated. Also the effect of changing resin which used in hand lay-up process, on composites strength properties and what we gained to composites properties. The composites are manifactured by hand lay-up process and dimensions are 25x25 cm and approximetaly 3-4 cm for thickness. Applied 40 bar pressure and used board molds. In this process effect of resin difference also investigated. With this process 8 hybrid 8 regular specimen manifactured. Polyester and vinly ester used as resins, methly ethylketon peroxide and cobalt used as hardeners. Tensile, flexural and impact tests applied on specimens. The effect on the mechanical properties of the material in line sequential ordef of the results obtained was investigated.
