Failure configuration and evaluation of hybrid CFRP-GFRP laminates using innovative Arcan fixture: Experimental and simulation approach

Abstract

This study successfully explored and evaluated the impact of notches modification in U, V, and square shapes on both tensile and shear strength using Arcan fixture. ASTM D 5379 was incorporated to evaluate the model then compared with FEA simulation. Composite material featuring a U-shaped notch possesses a notable advantage in terms of its tensile strength and shear strength values, which measure at 276.3 MPa and 14.9 MPa, respectively. 3D Hashin's damage model also employed to compare and validate the shear damage resulting from each notch of the experimental work. The composite with a U-shaped notch demonstrates excellent capacity for withstanding both tensile and shear loading without compromising its strength and fracture resistance in shear. the failure mode analysis was showed that the matrix failure tent to make weaker of the specimen, although the fiber still stands and kinked. The present study can be used as the leading method to evaluate the hybrid laminates applied in wind turbines, automotives body structures, and aircraft structures.
