Abstract: Globalisation has presented several challenges and the most important amongst them is 'protection of the environment'. Developing sustainable materials and natural fibres is one such step that has diverted lots of research interests. In the presented study, natural frequency response of nettle fibre-based composites was predicted through performing modal analysis using ANSYS software tool. The effect of cantilever beam thickness, width and length on the first mode natural frequency was studied using the finite element analysis (FEA) method and response surface methodology (RSM) was further used to examine the effects of process parameters on the output responses. The length of the composite beam showed maximum contribution (470.76%) followed by its thickness (273.62 %). Maximum natural frequency (313.01 Hz) at first mode was observed at the geometrical conditions of length = 250 mm, width = 75 mm) and thickness = 12 mm respectively.

Keywords: vibration analysis; modal analysis; natural fibre composites; response surface methodology; RSM; finite element analysis; FEA.
