Overview

The ICR.IAS JV has partnered with the University of Western Australia to conduct research on using our composite repair system, Technowrap^TM , on an I-Beam to reinstate the integrity of the structure.
Multiple beam test pieces had a 300mm section removed from the centre in order to simulate a loss of steel. In total four (4) beams were tested: 
(1) I-Beam intact with no sectional loss 
(2) I-Beam with 300mm section loss
(3) I-Beam with 300mm sectional loss repaired with 8 layers of Technowrap^TM SRS (Carbon Fibre)
(4) I-Beam with 300mm sectional loss repaired with 8 layers of Technowrap^TM 2K (Glass Fibre)

Results

• The I-beam repaired with SRS (Carbon Fibre) resulted in a 277% improvement from a "damaged" state and 86% of the original intact capacity. 
• The I-Beam repaired with the 2K (Glass Fibre) resulted in a 248% improvement from a "damaged" state and 80% of the original intact capacity.

Benefits

• Increased knowledge and capacity to work with complex geometries and large scale substrate loss especially with regards to failure modes.
• The testing output will be used alongside specialised composite engineering to build additional client confidence for site specific questions relating to critical works and emergent scopes.
