Abstract Natural fibers can be modified to increase durability and stability. Two technologies are presently commercial to improve both of these properties: reaction of the fiber with acetic anhydride (acetylation) and heat treatments. Both increase durability and stability. Mechanical properties are slightly improved…

Abstract Various methods have been developed to make molecular composites, including coagulation,in situpolymerization of a matrix polymer, and the addition of a rigid chain to a flexible chain in block copolymers. However, many systems eventually phase separate due to inherent immiscibility of component polymers on h…
Abstract This article describes the challenges encountered by helicopter airframe designers and the reasons why composite materials are increasingly used in their designs. The pros and cons of composite materials are discussed and examples of the use of composite materials are given. A discussion of the comparative co…
Abstract Compared to normal starch‐based materials, starch nanocomposites have attracted much interest in the recent years due to the drastic improvements in the mechanical properties, thermal stability, flame retardant properties, gas barrier properties, and so on. There are three main types of nanofillers that have…

Abstract This article presents a comprehensive introductory overview of thermoplastic composites manufacturing. From classical to reactive thermoplastics; fibers and textile structures to semifinished products; modern‐day manufacturing processes and post‐processing techniques to the manufacturing process chain associa…
Abstract Double‐curved composite parts can be obtained by the forming of an initially flat fibrous reinforcement. Because the preform is made of fibers, the deformation mechanisms during the forming are specific. The objectives of analyses and simulations of the forming process are both to determine the conditions tha…

Abstract SiC‐whisker‐reinforced ceramic exhibits much higher fracture toughness than monolithic ceramics, because the whisker bridging and pullout provide much large fracture resistance when the crack propagates perpendicular to the longitudinal direction of the SiC whiskers. Owing to the toughening efficiency and the…

Abstract When an electrically conducting dispersed phase is added in sufficient quantities to a polymeric resin, a conductive composite is formed. The unique properties of such composites make them technologically superior to or more cost effective than alternative materials in a variety of applications. The inevitabl…

Abstract Test methods for mechanical testing of fibrous composite materials subjected to tension, shear, and compression are presented. Material response into the nonlinear range and effective elastic constants are presented for selected composites.
Abstract Glass and glass–ceramic matrix composites represent a very particular type of composite materials. As in most ceramic matrix composites, the reinforcements are mainly intended to increase the resistance to crack propagation, that is, the most significant weakness of the matrices, due to several toughening mec…
