Natural fibers in composite materials have received growing interest for the last decades. Few works have explored the study of long vegetable fibers reinforcing composites such as textile reinforcements to develop higher performance of bio-materials which could be used in load-bearing applications. Therefore, the identification of new natural textiles should turn into an active research challenge for use as reinforcement in the development of green composites. In this study, leaf sheaths from Cocos nucifera L. was investigated. This material presents the distinctive feature to be naturally available as a textile. Thus, coconut leaf sheath was characterized morphologically, chemically, physically and mechanically. Coconut textile displays low Helium density and water sensitivity, promising thermal stability and tensile properties in both fibers directions forming the sheath. Compared to natural and synthetic textiles, coconut leaf sheath appears as a suitable, promising and competitive textile reinforcement for the development of eco-friendly continuous fibers composites.
