    Abstract

    In an effort to delineate the effect of storage time on strength, we have tested three types of Kevlar 49/epoxy strands up to 3.5 y after fabrication. The same fiber, Kevlar 49 (380 denier), was used with three different epoxy systems. The epoxy composition and cure cycles are listed in Table 1, and details of the test results are given in Table 2. Specimen preparation and test procedures have been reported elsewhere (for example, see Ref. 1). Note that in Table 2, failure loads were converted into fiber strengths using the fiber cross-sectional area.
