<P>Koyanagi presents a concise and practical guide to using a micromechanics approach to predict the strength and durability of unidirectionally aligned continuum carbon fiber reinforced plastics (CFRPs).</P><P>As the use of composite materials in becomes more widespread in various fields, material durability is becoming an increasingly important consideration, particularly with regard to UN Sustainable Development Goals. Using more durable composite materials would help with achieving these goals. Because the failure of composite materials proceeds via the accumulation of micro failures and micro damage, a micromechanics approach is indispensable for estimating precise durability.</P><P>In this practical guide, Koyanagi describes this approach and explains the precise durability of the composite materials with regard to the time dependence of micro failures. This book first explains the strength and durability of unidirectionally aligned continuum CFRPs. It then individually addresses
