This invention relates to a flame retardant fiber-reinforced composite material based on an epoxy resin composition which includes at least one epoxy resin having an epoxy functionality of at least 2 as well as at least one organic phosphinic acid or derivative thereof (e.g., an organic phosphinic acid-modified epoxy resin), reinforced with a fiber having a thermal conductivity?3 W/m.Math.K at room temperature, as well as a prepreg for making such a flame retardant fiber-reinforced composite material. More specifically, a composite material is provided that contains a combination of particular types of epoxy resins, curatives, and reinforcing fibers that provide sufficient flame retardance for thin-ply laminates when cured at 163? C. for 15 minutes. These cured composites are also suitable for a variety of applications requiring flame retardancy.
