ACCELERATED AGING OF PULTRUDED GLASS/VINYLESTER RODS

Results of aging tests on pultruded e-glass/vinylester rods are reported. Commercially pultruded glass/vinylester rods were subjected to a range of thermal, aqueous, chemical and sustained stress conditioning. Following the conditioning, the specimens were tested to determine the changes in their mechanical and physical properties. Flexural and short beam shear tests were used to determine flexural strength, flexural modulus and shear strength. Weight measurements, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) were used to determine weight, thermal properties and glass transition temperature. Optical microscopy was used to study material deterioration. Tests were conducted for durations of 7 to 224 days. The analysis of the data shows the importance of conducting baseline and control tests, as well as, using a combination of mechanical and physical tests to understand the mechanisms of material aging.
