Prediction of Long-Term Properties of Fiberglass Pipe Based on the Shift Factors Method

Abstract:

The design life of fiberglass pipe is 50 years. In order to ensure long service life of fiberglass pipe, long-term properties under service conditions is the most important performance. According to the polymer matrix composite material with viscoelastic properties, adopt equivalent principle and shift factors method combined with experiments to study the long term performance of fiberglass pipe, established a relatively simple for fiberglass pipes long-term performance prediction method. The experiments show that compliance of fiberglass pipe with all hoop winding increased by 148% after 50 years in 60% stress level.
