Validation of Experimental Hybrid Natural/Synthetic Composite Laminate Specimen Using Finite Element Analysis for UAV Wing Application

In this day and age, there are high demand for the utilisation of hybrid composite materials in industrial and aerospace applications due to its advantages over the common composite material and other materials. In this case, engagement of natural fiber with synthetic fiber to form a hybrid lamination composite to become a partially eco-friendly material had been studied and analysed to pursuit a properties requirement for UAV wing profile. In experimental study, glass and kenaf were fabricated in two variations of GKG and KGK and were tested under tensile test properties. The result obtained was compared by validation of finite element analysis using ANSYS 18.2 workbench. From the validation results, it showed a good agreement in stress and strain but percentage error in deformation due to several factors will be discussed. In term of composite strength, GKG have the maximum stress of 120.89 MPa compared to KGK with 79.787 MPa maximum stress.
