This work aims to compare the hardness (H) and roughness (Ra) of glass/epoxy composites after being exposed various hostile environments, which is possible because constituents are always same. Considering stacking sequence [452, 902, -452, 02]s, increases for all solutions up a certain exposure time, from it decreases longer immersion times. For same sequence, had its highest increase (around 44.5%) alkaline solution 36 days immersion, while decrease 25%) occurred mortars 30 exposure. [02, 902]2s, varied in opposite direction acidic solutions, observing direct H with time. However, samples immersed oil, decreased as function In terms roughness, there was linear time samples, increased linearly. Therefore, can be concluded that has significant influence on roughness. Furthermore, knowledge variation very important associated structural response composite environments.
