Strengthening of Glass Fibers: I, Cladding *

摘要: Experiments on development of internal stress in fibers by cladding borosilicate glass with 96% silica are reported. The axial compression the cladding, determined photo-elastically, agreed well increased strength tension fracture experiments. In turn, these results compressive predicted analysis when proper allowance was made for stresses which can develop core is fluid and rigid.
