Fabrication and characterisation of kenaf fibre reinforced polyamide biocomposites for railway sleeper applications

Railway passing traffic, speed, and load have significantly increased over the years, prompting industry stakeholders and researchers to seek an alternative sleeper material that can demonstrate its ability to potentially possess higher in-service bending resistance and be environmentally friendly a...
