Developing new natural fibre reinforced composites is the focus of many researches in recent years. Natural fibre reinforced composites are made from renewable resources and they have less environmental effect in comparison to inorganic fibre reinforced composites. Among the natural fibres, luffa cylindrica fibres are widely available throughout the world. Luffa fibres are known to have lignocellulosic fibre characteristics. In this study, luffa cylindrica fibres were treated with acetic acid by using conventional, ultrasonic and microwave methods, then thermoplastic composite structures were produced by using raw and treated luffa cylindrica fibres as reinforcement material. Finally heat conductivity properties of the luffa cylindrica fibre reinforced polyethylene composite structures were investigated.
