      Abstract 
       Composite materials became suitable for structural applications when boron and carbon fibers emerged as commercial products in the late 1960’s.During the last 40 some years much research and development effort in Japan and the US have resulted in major impact on structures for aircraft and spacecraft.  The all-new Boeing 787, for example, is made with 50 plus percent of the structures in composites, 30 tons per plane.  The fan blades of its engines by General Electric are also composites.  This presentation will describe how the design processes of composites for aircraft structures.  Composites are now commercial products and have outstanding properties that combine high stiffness, low weight, and durability against corrosion and fatigue.  When weight or durability is important for a system composites are unmatched.  For any engineer interested in high performance structures composites should be one of his/her options.
 
      BIOGRAPHICAL SKETCH
      Professor Tsai was a student at Yenching University and went to the US in 1948.  He graduated from Yale Unverisity with BE and D.Eng.  He started his work in composite materials in the early 1960’s.  Prior to Stanford University he worked for Ford, Washington University, and the US Air Force Research Laboratories.  He served 25 years as the first Editor-in-Chief of Journal Composite Materials.  He is best known for his books on composites and Tsai-Wu failure criterion.  He is a member of the US Academy of Engineering.  He has been an adjoint professor at Beijing University of Aeronautics & Astronautics. He is often introduced as the father of composites.

美國國家工程院院士，斯坦福大學終身教授Stephen W. Tsai(蔡為侖)博士簡歷：

Tsai教授畢業於美國耶魯大學🛀🏽，1952年, 1961年分別獲學士和博士學位，之後長期在美國斯坦福大學航空航天系擔任教職。Tsai教授是國際復合材料力學界的權威，在1968年他和著名力學家R. Hill合作🪡🦁，提出了Tsai-Hill(蔡-希爾)強度準則🏄🏽，對復合材料力學的強度理論產生了深遠影響，沿用至今。1971年又提出了張量形式的Tsai-Wu(蔡-吳)強度理論👩🏼‍🔧。Tsai-Wu理論的數值計算與實驗符合的相當好。此外，Tsai教授在復合材料各向異性非線性變形性能的分析方面👩🏽‍🚀，也做了開創性的研究工作。

Tsai教授是美國國家工程院(the National Academy of Engineering)院士，長期活躍在國際復合材料力學學會上🧑🏿‍🦲，他也是the American Society of Mechanical Engineering和the Society of Aerospace Materials and Process Engineers的成員。Tsai教授編著出版了不少復合材料力學的教材👩🏼‍🍼，和復合材料設計方面的著作。國內翻譯出版了他的專著🦻：蔡為侖，復合材料設計（The design of compositematerials）🌴💅🏽，北京，科學出版社👨‍👨‍👦，1989👩🏼‍🦰。
