Combined Effects of Sustained Loads and Wet-Dry Cycles on Durability of Glass Fiber Reinforced Polymer Composites

Figure 6

Tensile strength of stressed specimens (a) subjected to WD cycles of distilled water and different loads; (b) subjected to WD cycles of saltwater and different loads; (c) subjected to WD cycles and 20% ultimate tensile strength; (d) subjected to WD cycles and 40% ultimate tensile strength. Note. WWD2 and WWD4 are specimens exposed to WD cycles of distilled water and subjected to 20% and 40% ultimate tensile strength, respectively, and SWD2 and SWD4 are specimens exposed to WD cycles of saltwater and subjected to 20% and 40% ultimate tensile strength, respectively.
