The Evaluation of Mechanical Properties for Laminated Composite Materials with Different Fiber Orientation

Multilayer laminated composites are often effective. The test procedure development and experimental setup focused on identifying damage mechanisms during the testing of laminated composite specimens. The manufacturing process of multilayer composite materials uses orthogonal fiberglass, random fiberglass, and carbon fibers. A central layer of woven unidirectional carbon fiber fabric (SikaWrap-300 C), along with two layers on top and bottom featuring different fiber orientations of random fibers and glass fiber, was used to create the recipes. The results show the absorbed energy, the impact strength, and the orientation of two layers of glass fiber with (0°/90°) s fiber orientation; these have the maximum absorbed energy (14.89 J) and impact strength (248.1 kJ/m2) due to the symmetrical arrangement of layers and uniform distribution of energy through layers. Conversely, the orientation of two layers of glass fiber with (0°/90°) 2 have minimum absorbed energy (1.63 J) and impact strength (50.3 kJ/m2) because of the unsymmetrical arrangement of layers. Flexural results with different layer orientations showed that the 90° orientation of the two layers of glass fiber proved to be the most efficient for offering resistance and stiffness to the multilayer composite material.
