疊層複合材料最大?度視纖維方向與負荷情況而定，當負荷隨工作情?之改變而改變時，原最佳設計?可能有?度不足 之虞，故於結構設計中?應對此種可以預見之危險預加防範。
本文?就交互影響最烈之情?，針對二及三層疊板與圓筒考慮之，而以修正?金分割?索法，依纖維方向之變化，沿疊 層厚度各點求其高低極限?度。雖以試樣大量製作困難，所得數據有限，然理論推算與試驗結果甚?吻合，由於本研究之結 果，將可使吾人對複材結構之極限設計?生高度之信心。 - 英文摘要：
The ultimate strength of composite laminates depends on the fiber orientation and loading condition. An original optimum design might have inadequate strength as the loads change out of change of operation. Precautions should be taken against such foreseeable hazards in the structural design of composite materials.
In this work, the two- and three-layered laminated plates and cylindrical shells are considered for the worst case conditions of coupling. The golden section search is modified for the global maximum and minimum strengths in terms of fiber direction at selected points across the laminate thickness. Predictions are consistent with experimental results, though they are limited due to difficulty in the exhaustive specimen preparation. This research will lead to a high degree of confidence in the extremal design of composite structures. - 中文關鍵字： --
