LAMINATE STRENGTH CHANGES AFTER TEN-YEARS AGING

Abstract

This report contains flexural strength data showing the effects of ten-year aging on epoxy and polyester laminates. Small reductions in strength were noted in 18 of the 20 cases where comparisons could be made. Epoxy and polyester laminates maintained their strength properties equally well. Modulus values for the epoxy laminates were reduced in all but one case in amounts from 5 to 16%. The aging effect on the modulus of polyester laminates, on the contrary, was to increase the values from three to 13%.
