| description.abstract | Polymer composite materials have received increased attention for applications in cryogenic
environment because of their light weight and unique properties. The research presented in this
paper is an effort to understand the interlaminar fracture behavior of glass/epoxy composite
laminates at cryogenic conditions and at different loading rates. This study uses 3-point flexural test
to qualitatively assess such behavior for 50 weight percentage of E-glass fibers reinforced epoxy
composites during cryogenic and ambient conditions. The specimens were tested at a range of 2
mm/min to 500 mm/min crosshead speed to evaluate the sensitivity of mechanical response during
loading at these conditions. The mechanical performances of the laminated specimens at cryogenic
conditions were compared with room temperature property by using SEM photographs.
Phenomenological behavior of these materials may be attributed by polymer relaxation, lowtemperature
hardening, matrix cracking, and misfit strain due to differential thermal coefficient of
the constituent phases and also by enhanced mechanical keying factor by compressive residual
stresses at cryogenic temperatures. | en |
