摘要： A fiber-reinforced resin composite material includes first and second members. The first member includes a first fiber and a first matrix resin. The first fiber includes a reinforcing fiber and is impregnated with the first matrix resin. The reinforcing fiber has a melting point and a tensile strength higher than those of an aliphatic polyamide fiber. The second member includes a stack and a second matrix resin. The stack includes a second fiber and a third fiber filled with the second matrix resin. The second fiber includes the reinforcing fiber. The second matrix resin includes a component common to that of the first matrix resin, and includes a first polyamide resin that includes an aliphatic polyamide resin. The third fiber includes a second polyamide resin that includes an aliphatic polyamide resin and has a melting point higher than that of the first polyamide resin by 7 to 50 degrees centigrade.

摘要： This invention relates to a flame retardant epoxy resin composition which includes an epoxy resin structure having an epoxy functionality of 2 or more with a measured total heat release value of not more than 23 kJ/g as well as an organic phosphinic acid structure (in reacted or unreacted form), as well as a prepreg, and a fiber reinforced composite material prepared using the epoxy resin composition. More specifically, an epoxy resin composition is provided that contains a combination of particular types of epoxy resins and curatives that provide sufficient flame retardance when cured at 163° C. for 15 minutes. The epoxy resin systems are also suitable for preparing a fiber-reinforced composite material that will also provide sufficient flame retardance for a variety of applications.
