Question

Figure 1 shows the dimensions of a sandwich structure. Assume that a sandwich panel has a face volume fraction of 0.3, the density of the core is 400 kg/m^3 and the density of the face sheets is 2000 kg/m^3, use Equation 1 to determine the homogenised density of the sandwich panel. Give your answer in kg/m^3 correct to 3 significant figures.\\ $\tilde{\rho} = f\rho_f + (1 - f)\rho_c$ Eq (1) Figure 1. Dimensions of a sandwich structure. Answer:
