A Study on Design of Frame Tube Bike Composite for Reducing Stress and Deformation Based on CEN 14766 Standards Test Methodology

In the previous study, frame tube design analysis is developed to provide a significant reduction in stress and deformation. This study aims to analyze the frame tube composite design. The design analysis by using FEM software is used to model frame tubes with shell elements. The layer angle orientation is set as design parameters. Material is carbon fiber composite (epoxy E-glass UD). Dimension thickness is 2 mm. Seat tube angle 74.5o and head tube angle 70.5o . Load is applied in static condition with weight loading on 80 Kg. Based on the simulation results, the smallest deformation and stress values occur in the model with a layer orientation angle of [45o , 90o , 90o , 45o ] with a deformation value of 0.099556 mm and a stress of 10.016 MPa.
