Abstract: Aim of this work was to review information about natural long fibres reinforced composites focusing on interface, wettability, fibre-matrix adhesion, moisture absorption, correlating them with macroscopical mechanical properties. Weak fibre/matrix interface does not permit a complete performance exploitation in composite materials. Physical and/or chemical treatments can enhance adhesion and increase performances. Chemical treatments based on the employment of Sodium Hydroxide, Silanes and Maleic Anhydride are the most common in literature and have been reviewed with particular attention on mechanical performance improvements. In this work have also been described different used methodologies and critically analysed previous results and future applications.
Keywords: natural fibres; fibre reinforced composites; interface; chemical treatment; mechanical properties; wettability; fibre-matrix adhesion; moisture absorption.
