Abstract
Today, composite materials are widely used in various industries due to their unique properties. In the meantime, considering the special application of thermoplastic composites, especially in the aerospace industry, the mechanical properties and fracture behavior of these materials should be evaluated. One of the important processes in the production of thermoplastic composite parts is the HOT PRESS production process. Considering the high durability of these materials and the type of place of use, in addition to examining the mechanical properties, the failure and fatigue life of these materials should also be examined. In this paper, the main goal is to investigate the mechanical properties and failure behavior of the mixed mode (I/II) in the Glass/PP continuous fibers composite. For this purpose, Glass/PP continuous fiber composite was made by HOT PRESSING method. Then, using experimental methods, the composite mode failure behavior (I/II) of this material was evaluated using the fabricated MMB fixture. Finally, the experimental and analytical values of stress intensity coefficients and fracture energy in the mixed mode (I/II) will be reported.
