Manalo, Allan C. and Karunasena, Warna and Sirimanna, Chamila and Maranan, Ginghis B. (2014) Investigation into fibre composites jacket with an innovative joining system. Construction and Building Materials, 65. pp. 270-281. ISSN 0950-0618


The effectiveness of fibre reinforced polymer (FRP) composites jacket for pile rehabilitation relies mostly
on the continuity of repair system. This paper presents the development of a new type of FRP jacket with an innovative, easy-fit and self-locking mechanical joining system and the evaluation of the suitability of this composite repair system for pile rehabilitation and concrete formwork. An intensive characterisation of the mechanical properties of the composite resin for the interlocking teeth and locking key of the jacket was conducted. Similarly, finite element (FE) simulation on the behaviour of the FRP jacket subjected
to internal pressure was performed and verified through full-scale experimental testing. The results showed that the use of a microfibre composite resin provide the highest capacity joint. Further, the embedment of an FRP rod in the locking key resulted in an FRP jacket with a better joint performance.
The results of the FE simulations showed a good agreement with the experimental results in predicting the lateral expansion in the elastic stage, capacity and failure behaviour of the FRP jacket.
