Composite Structure 3Problem ObjectiveThe aim of the problem is to find out the link between fibre volume fraction and the transverse Young’s modulus through an FE analysis of the structure. Using the Abiquos application, we change the radius of the fibre to determine the fibre volume fraction. An RVE analysis for reaction forces yields shows the radii as in the figure below:Abaqus Analysis1.Given, r = 2 μm, a = 10 μm, therefore Vf= 0.0756Mesh seeds at displacement = 0.1 μm applied at right edge;
