Four small pieces of the fiberglass composite material were used for compatibility testing. Each piece had its initial weight recorded. Each piece was placed in a vial of 10ml of a one of the previously identified solvents (1-propanol, Thiophene, 1-Butanol, Dowanol PnBGE). The vials were placed on an automated roller to subject the vials to slight agitation. The pieces were left to soak overnight. The next day, the pieces were removed from the vials in order to record their final weights. They were also visually analyzed to see if any of the solvents cause shape, hardness, or other property changes.
