Experimental investigations on glass Fibre reinforced Polymer composite Pultruded sections and transmission line towers Modules

The mechanical and environmental properties of Glass Fibre Reinforced Polymer (GFRP) composite pultruded members of angle, channel and box section with crush % under compression have been compared. Performance of various connections in GFRP composite pultruded members using adhesive, bolt and hybrid joints including crush % under compression have been evaluated. Fabrication of 3D tower module using different GFRP composite pultruded members have been done and tested for compression and investigation of connection behaviour including crush % have been carried out. Based on the investigations conducted, the performances of GFRP pultruded sections under different loading conditions and performance of various types of connections in GFRP composite pultruded sections have been discussed. The outcomes of 3D GFRP tower module made up of various sections have been presented and the best performing combination have been identified. A 110 kV Transmission Line Tower (TLT) model out of GFRP composite pultruded angle section have been fabricated for conducts load test.
