The role of low temperature impact damage and freeze-thaw exposure on post impact compression strength of glass fibre reinforced polymer-matrix composite materials

An experimental study of the role of sub-zero temperature impact
damage and subsequent freeze-thaw exposure on post impact
compression strength of quasi-isotropic glass fibre reinforced vinyl
ester resin composite materials using non-crimp reinforcements
typically applied in the marine industry is presented. Specimens cut
from composite plates were impact loaded at two different temperatures
according to ASTM D7136, then immersed in fresh water until
saturation before being subjected to various number of ASTM C666
freeze-thaw cycles. After the freeze-thaw cycles, the specimens were
compression tested using a Boeing anti-buckling device according to
ASTM D7137.
