The sandwich pipe is created using non-reinforced material for the core layer and an alternate-ply material for the skin layers. Considering the complicated material properties of the skin layers reinforced by alternate-ply composites, the analysis is based on treating typical sandwich pipes that are three-dimensional, cylindrical, and orthotropic. The computer model conducts stress and strain analysis of sandwich pipe with different winding angles. The optimum winding angles have been found to be in the 60\textdegree range, and the strength of the sandwich pipe has been found to decrease rapidly when the core layer modulus is less than 20 GPa.
