An Experimental Analysis on the Impact of the Epoxy on the Torsional Behavior of Composite Fiber-Glass

Abstract

The value of the torsion test is of particular interest to this line of investigation, which intends to explore the effects of epoxy % on fiberglass (a composite material). The practical result demonstrates that an increase in the percentage of epoxy has a clear impact; it was noticed that an increase in the percentage of fiber-glass results in an increase in the values of torque (T) and angle (ϴ). Three samples of epoxy and fiber are ascribed, with rates of -(Epoxy) +(Fiber Glass) being (0.5%,1%,1.5%), and three samples of polyester and fiber are credited, with rates of -(polyester) +(Fiberglass) being (0.5%,1%,1.5%). Additionally, three samples of epoxy and fiber are attributed, with rates of -(Epoxy) +(Fiberglass) being (0.5%,1%,1.5%). We get the best results for the torsion test with the first specimen (0.5% fiberglass for polyester) and the best results for the shear strain with the fourth specimen (0.5% fiberglass for epoxy). Both of these results are 120 MPa for the torsion test and 2.2 for the shear strain.
