PROBLEM TO BE SOLVED: To provide a method of placing prepreg tows in high angle transition regions on a substrate during automated layup of composite laminate structures.SOLUTION: Prepreg tows 32 are placed on a substrate, the substrate having a bend 35 with a curvature extending over a transition region 28 in the substrate. The tows 32 are steered to and laid on the substrate separately in at least a first section 42, 44 and a second section 46 within the transition region 28, and each of the first section 42, 44 and second section 46 has an angular φ orientation that is less than the curvature θ of the bend 35 so as to reduce gathering of the tows 32.

    【課題】複合積層構造体を自動レイアップする際に、下地上の広角遷移領域にプリプレグ・トウを配置する方法の提供。【解決手段】プリプレグ・トウ32が、下地上に配置され、当該下地は、下地の遷移領域28にわたって延びる、ある曲率の曲げ部35を有し、トウ32は、遷移領域28内において、少なくとも第1部分42、44と第2部分46とに分けて、下地上に誘導及び敷設され、第1部分42、44及び第2部分46のそれぞれは、曲げ部35の曲率θよりも小さい角φ配向を有していることによって、トウ32のギャザリングが低減される方法。【選択図】図7
