摘要

A comparative analysis was carried out on long carbon fibres-epoxy composites cured with two different curing agents: an industrial product (a polyamine), and a "tailored" one (by modification of the chemical structure of the same amine). The characteristic of most interest of the latter curing agent is the capacity of hardening of DGEBA-TYPE epoxy resins at room temperature. On composites cured with the two different hardeners tensile and creep tests were carried out and Even a study of the fracture mechanics (by the caustic method), in order to evaluate the behaviour Of composite cured with a modified amine and to compare it with that of the composite hardened With the numodified amine.
