THE RAPID DEVELOPMENTS IN COMPOSITE TECHNOLOGY, WHICH OCCURRED PRIMARILY IN THE 1960S IN THE AEROSPACE FIELD, ARE CHRONICLED IN THIS BOOK. BECAUSE THIS FIELD IS ADVANCING RAPIDLY, THE MATERIAL IN THIS BOOK IS NOT COMPLTELY UP-TO-DATE; HOWEVER, IT IS STILL REMARKABLE VALID IN PROVIDING A REVIEW OF THE FUNDAMENTAL TECHNOLOGICAL BASE IN THIS FIELD.
Al3Ni whisker reinforced aluminum was found to exhibit excellent toughness and little notch sensitivity even though its room temperature tensile elongation is only 2%. This excellent toughness is maintained at liquid nitrogen temperature (-196 C). It is postulated that this remarkable behavior is due to the presence of a continuous metal matrix which provides sufficient localized ductility in the vicinity of the crack tip to absorb considerable energy from the ...
