STRENGTH OF GLASS FIBERS 151

ACKNOWLEDGEMENTS

I thank the conference organizers and especially Prof. Manual Elices for the invitation
to this conference, my colleague and ‘Strength Guru’ Chuck Kurkjian for many
enlightening discussions, Scott Glaesemann of Corning Inc., for providing me with
reprints and preprints about his recent work on large flaws, Hyungchan Kim for
scanning all figures in this manuscript, and NASA grant NAGS-1470 for the support of
part of my time spent in writing the manuscript.
