An impact damage size of 1" or greater may significantly deteriorate the compressive strength of the composite part (see Fig. 2) and may need immediate repairs and must not be discounted despite being characterized as BVID. This is the significance of 1" impact damage size. With the increasing occurrence of BVID in composites, detection methods needed to be developed to characterize the impact ...
