Abstract
Hand lay-up molding is used for preparing sheets of epoxy composites
reinforced with chopped strand mat (randomly direction) glass fibers by weight
fraction of (44%). The sheets were left to solidify at room temperature (23± 2) ˚C. The
samples immersed in (HCL, KOH, distilled water, Benzene, and Kerosene) for equal
period of time at constant temperature (23± 2) ˚C. The impact and compressive
strength were calculated for the samples before and after immersion in different
chemical solutions.
The results shown that the impact strength of the samples that immersed in
(HCL, KOH) solutions were decreased after immersion, while the impact strength of
the samples immersed in (distilled water, Benzene, Kerosene) were increased after
immersion.The results showed also that the compression strength of the samples
immersed in (HCL, KOH, distilled water) decreased after immersion, while the
compressive strength of the samples immersed in (Benzene, Kerosene) were increased
after immersion. Finally the results showed that the maximum relative mass gain
(minimum absorption resistance) was of the samples immersed in (HCL) solution in
both impact and compression test. While the minimum relative mass gains (maximum
absorption resistance) was of the samples immersed in (KOH) solution in both tests
