This paper is based upon introductory remarks presented at the opening of the ASTM Symposium on Damage in Composite Materials. The cooperation between specialists in fatigue and in nondestructive testing, in the organization and implementation of the symposium, is marked as a noteworthy milestone in an era in which closer cooperation between these two groups will be needed in order to achieve enhanced quality in materials and manufactured products. Experiences with an unusual form of damage in pultruded guys for antenna support systems are described to show that the development of meaningful test methods for composites may benefit from unconventional approaches. It is suggested, furthermore, that the development of voluntary standards for the nondestructive characterization of composite materials will succeed only to the extent that individuals with the relevant competences are encouraged to contribute to this important activity. |
