Abstract
W. F. THOMAS recently pointed out1 that E glass fibres in the size range 0.0002–0.0006 in. had a very consistent strength of 540,000 lb./in.2, when tested on a 1-in. gauge length. This is equivalent to an elastic failing strain of about 5 per cent. Other workers have found the strength of untouched glass fibres drawn in a similar way to be lower and more variable, depending on the conditions under which the fibres were formed2 3.
