Rule of mixtures (RoMs) of composite materials is continuously modified according to different component materials and their composition forms to play the role of theoretical verification and evaluation. This paper studied the regular relationship between the bonding surface and mechanical performance of the composites. The three bonding surface designs were made into PLA/EP test samples by 3D printing technology. The tensile and bending properties of the composite materials were proved to be stronger than the average of those of their component materials. The mechanical properties show regular changes with the bonding surface and structural design. The bonding surface between components is an important reference information that cannot be ignored for the performance prediction and adjustment of laminated composite materials.
