Characterization of Composite Materials

Experimental characterization of the mechanical properties of E-glass/Epoxy & E-glass/Polyester composite was conducted. The effect of strain rate on E-glass/epoxy and E-glass/polyester has been investigated & experimentation was performed to determine property data for material specifications. E-glass/polyester laminates were obtained by compression molding process and E-glass/epoxy laminate by hand lay-up vacuum assisted technique. The graphs that are obtained from the tests were documented. This research indicates that the mechanical properties are mainly dependent on the strain rate. It can be conclude from the result that E-glass/Epoxy show better property with the increase of strain rate, so this material is suitable for structural automotive body panel applications.
