Abstract : Measurements of the effect of tension on monofilament during resin cure are reported for fiber stress from 36,000 psi to 160,000 psi. Tests on the effects of humidity cycling of epoxy coated single E-glass fibers were completed and the results are reported. The static fatigue studies on virgin E-glass fibers coated with epoxy resin were completed. The resultsARE REPORTED FOR TEMPERATURES UP TO 600 F and load durations up to 10 min. A method of experimentally confirming the derived biaxial stress-strain equations is described along with an apparatus for making bending and twisting load-deflection tests. A device constructed to make biaxial stress-strain and photoelastic tests is described. (Author)
