Solidified hollow, preferably long blow molded, articles made from at least one thermoplastic composition comprising short aramid fibers. Processes and compositions for making such articles. Methods of improving the melt strength of polymer compositions by introducing therein an effective amount of short aramid fibers. Methods of making blow molded articles from polymer compositions not suited for blow molding. L'invention concerne des articles solidifiés creux, de préférence longs et moulés par soufflage, conçus à partir d'au moins une composition thermoplastique renfermant des fibres courtes d'aramide. L'invention concerne également des procédés et des compositions de fabrication de tels articles, ainsi que des procédés permettant d'améliorer l'état de fusion de compositions polymères par introduction d'une quantité efficace de fibres courtes d'aramide dans celles-ci. L'invention concerne enfin des procédés de fabrication d'articles moulés par soufflage à partir de compositions polymères non conçues pour le moulage par soufflage.
