Abstract
The embodiments relate to a polymerizable thermoset composition having improved flame retardant properties, a polymerized thermoset having improved flame retardant properties, a process for manufacturing the polymerized thermoset, and use of the polymerizable thermoset composition to produce lightweight construction components, preferably carbon fiber composites (CFRP), and a lightweight construction component, preferably carbon fiber composite (CFRP), containing the polymerized thermoset.
Claims10
