Polymer composites have been used in various applications, such as automotive, aerospace, construction and packaging; and their market is growing immensely (Hsiao and Heider 2012; Mngomezulu et al. 2014). Man-made fibres such as glass and carbon have been used as reinforcing agents in polymer composites to enhance their performance. However, the combination of one or two fibre-reinforced polymer composites, also known as ‘hybrid composites’, have also been studied (John and Thomas 2008). After the end of service life, these high-performance materials are disposed off in natural environments because they are not recyclable as the separation of their multiple components is quite difficult. This leads to environmental pollution, which is often an eyesore and harmful to the environment.
