Abstract : A theoretical review and new analytical derivations are presented which give a reasonably detailed coverage of the state of the art concerning strength theories for glasses, experimental evidence of the strength/size relationship in glass fibers and a newly completed analysis predicting the interrelationships between variables for glass fibers drawn from rods. The theoretical analysis shows that there is a very real limitation of fiber size such that no fibers below a certain diameter can be drawn in monofilament drawing operations. This clearly indicates that ultra fine diameter fibers may be obtained only by the bundle drawing process. The feasibility of the bundle drawing process in producing very fine glass filaments within bundle drawn fibers has been shown experimentally. Protective metallic coating techniques have been developed but require further work before the method becomes capable of producing discrete ultra fine fibers with enhanced strength characteristics.
