Thermal and degradation behavior of fique fiber reinforced thermoplastic matrix composites

The influence of untreated and treated fique fibers on the crystallization process and thermal degradation of different thermoplastic matrix composites has been evaluated. The fique fibers have been treated with different chemicals according with the type of thermoplastic matrix employed. Additionally, a copolymer of poly(propylene) with maleic anhydride (MAPP) has been used as compatibilizer. The treatments introduce an increment on the thermal stability of fique fibers respect to untreated fibers. Crystallization is affected by the presence of fique fibers showing important differences for each type of composites. Fiber presence has an important influence on the matrix morphological characteristics, as observed by dynamical mechanical analysis.
