ABSTRACT

The objective of the present work is to evaluate mechanical tests (tensile, compression and Flexural) of pultruded bars which are made up of E-glass reinforced with Epoxy resin in short-term aged test conditions. Experiment on 151 FRP pultruded bar samples with varying diameters (12, 16 & 20 mm) being carried out at two phases. In the first phase FRP pultruded bars were exposed to different diffusion aging conditions to determine their structural credibility. The second phase involved in conduction of mechanical tests (tensile, compression & flexural) using Universal Testing Machine. The tensile test on bare and aged samples shows reduced physical strength. Maximum tensile strengths of unaged FRP bars of 12mm diameter found to be 463.6 MPa, as that of 60 days aged specimen found to be 412.6 MPa. The compression tests were conducted and a maximum compressive strength of bare specimens was found to be 408 MPa, as the specimens subjected to aging for 60 days in salt water, the strength of the specimen found to be decreasing by 19.64%. The reduced tendency of strength found in flexural mode, and found that 8.3% of decreased flexural strength. All the mechanical test results show the reduced physical strength when compared between aged and unaged specimens.
