N2 - This paper investigates the effects of fibre angle orientation on the failure behaviour and natural frequencies of Kevlar epoxy and glass epoxy laminates under uniaxial tension. The laminates, consisting of 24 layers with a layup sequence of [θ4, 0, −θ4]s was analysed across fibre angles from 0° to 90°. The minimum load for layer failure was determined using the Maximum Stress Theory based on First Ply Failure (FPF) criteria, and natural frequencies were measured for Modes 1, 2, and 3. Numerical validations confirmed the accuracy of the finite element models employed. The results indicated a decrease in laminate strength as the fibre angle increased from 0° to 90°, with Kevlar epoxy dropping from 1380 MPa to 149.11 MPa, and glass epoxy decreasing from 1035 MPa to 47.18 MPa. Concurrently, Mode 3 natural frequencies showed an increase, rising from 1994.82 Hz to 2191.50 Hz for Kevlar epoxy, and from 1858.89 Hz to 1726.76 Hz for glass epoxy, while Modes 1 and 2 exhibited varying trends. This study enhances understanding of the relationship between failure behaviour and natural frequencies in composite laminates.
