摘要： A prepreg contains: a reinforcing fiber material; and a resin composition with which the reinforcing fiber material is impregnated. The resin composition contains an epoxy resin, an amine curing agent, and an imidazole curing agent. An amount of the amine curing agent is less than or equal to 3.8 parts by mass, relative to 100 parts by mass of the epoxy resin, and a sum of the amount of the amine curing agent and an amount of the imidazole curing agent is less than or equal to 10 parts by mass, relative to 100 parts by mass of the epoxy resin. The fiber-reinforced composite material is a cured product of the prepreg.

摘要： Die Erfindung betrifft ein Hochtemperaturharz, einen Formkörper daraus und einen Verbund aus dem Formkörper und einem Element eines leistungselektronischen Bauteils. Durch die Auswahl, Kombination und/oder Mengenanteile der Inhaltsstoffe können die Harzzusammensetzungen nach der vorliegenden Erfindung für eine breite Palette von Anwendungsformen und Prozesse wie Vergießen, Bonden, Abdecken, Verkapseln, Füllen, insbesondere "underfill" und/oder "sidefill" leistungselektronischer Bauelemente eingesetzt werden. Die Harzzusammensetzung stellt damit Produkt- und Systemlösungen, die hohe Einsatztemperaturen und eine ausreichend hohe elektrische Durchschlagfestigkeit für Anwendungen in der Leistungselektronik erfordern, bereit. Hinzu kommt die Konformität der Harzzusammensetzung mit den Anforderungen an so genannte "green products", die hier erfüllt werden.
