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.
