Introduction Lignocellulosic fibers have several advantages to be used as reinforcement in polymer-matrix composites. One can cite, for example, their biodegrability and their neutrality in respect to CO 2 emission [ 1

Abstract  

Flame retardant additives offer a potential short-term solution for reducing the combustibility of composites, and hence the reduction of the associated hazards. A brief review of fire modelling was performed to identify suitable mathematical expressions with which the results of the experimental flame retardant investigation were analysed. These were then used in a limited trial to compare the experimental and calculated ignition parameters. The comparison of simple mathematical equations with fire test results indicated that their ability to reasonably reproduce the experimental ignition parameters of the flame retardant treated composites is dependent on the mechanism of flame retardant activity, particularly the stage of combustion at which it is designed to be active.

Introduction Growing awareness for an eco-friendly environment has revived the interest to develop composite fibers from biobased products. Considerable interest has been generated to use natural fibers with thermoplastic

Introduction Efficiency of composite materials depends mainly on the properties of the individual components as well as interface between fibers and matrix. Incompatibility is among the main obstacles facing today's very
