Fiberglass-Reinforced Plastic (FRP) Performance Under Thermal Upset Conditions

Thermal upsets can occur in many processes where heat and chemical reactions are present. Some materials of construction perform well in spite of thermal upsets--even when these upsets are two or three times normal operating temperatures.  The purpose of this paper is to examine the impact of thermal upsets in the range of 2.4 - 2.7 times normal operating temperatures on FRP materials of construction.  More specifically, the test environment was designed to simulate a chimney liner operating at 65ºC (150ºF) with thermal upsets of 182ºC (360ºF) and 204ºC (400ºF) respectively. The results will show the effect of the type of resn and veil on the performance of FRP when subjected to the test environment described above.
