Abstract
Polypyrrole (PPy) was deposited on carbon fibres via the oxidation-polymerization of pyrrole (Py) with ferric ions. These PPy-deposited carbon fibres were then made into composite boards with epoxy resin. The interfacial bonding between carbon fibre and epoxy resin was evaluated by measuring the interlaminar shear strength (ILSS), tensile strength before and after impact (TAI), and flexural strength. Experimental results show that deposition of PPy can improve the ILSS, tensile strength, and flexural strength. Furthermore, TAI is also reduced by the deposition of PPy. The interfacial bonding was the highest when the carbon fibre was immersed in 20 wt% FeCl3(aq) and then reacted with 0.5 M Py in acetonitrile for 20 min.
