For this purpose, the importance of polymers, different fracture modes and testing methods are studies. The three-dimensional models of the fixtures for the Compact Tension (CT) and Single Edge Notch Beam (SENB) tests are prepared and fabricated. Specimens for Mode I testing were prepared using Polyester. The tensile test is performed to determine modified parameters required in the calculation of the fracture toughness. The experimental results obtained from CT and SENB are compared. Taking the standard deviation results CT provided a smaller value of deviations as well CT specimen showed a lower average value for the fracture toughness of the polyester. © 2021 The Authors.

Introduction A polymer matrix composite (PMC) is a composite material made of numerous short or continuous fibers held in conjunction by a polymer matrix. To study PMC behavior, we need to know how polymers as PMC’s constituent behave. Polymers can exist in two states; natural or synthetic. Examples of natural polymers are amber, wool, silk and natural rubber.
