Study on durability test methods for pultruded GFRP structural material

 ABSTRACT

Three types of accelerated test and an outdoor exposure test were conducted for three types of pultruded GFRP plates with different matrix resin: unsaturated polyester, vinyl ester and phenol resin, including their painted specimens. Weight change was evaluated through the tests. All of the outdoor-exposed specimens without paint showed weight decrease from about 100 days, however, the painted specimens showed no remarkable weight decrease for 1000 days. An accelerated test in moist air and a weather meter showed similar changes
