Fiber placement is an important processing technology for fabricating complex composite structures which offer many advantages over traditional structural material.In this paper, a novel path planning algorithm for closed surface is proposed, which take midline and edge of tows as placement curves alternatively instead of achieving midlines and edges separately.The iterative method for placement curves is introduced under the constraint of curvature of tows.The planning of placement curves for the whole surface is achieved by offsetting curve feature points, which aims to produce uniform lay-up of composite lamina, with controllable gap and overlap between subsequent tows.The method to calculate the number of tow is also put forward no matter the maximum tow number is even or odd.Finally, the proposed algorithm is verified by simulation with CATIA Component Application Architecture (CAA).
