Kinetic modelling of the stabilizing effect of carbon fibres on thermal ageing of thermoset matrix composites

The stabilizing efficiency can be described satisfyingly by the ratio ϕ8 equal to the number of PO2 radicals scavenged by carbon per propagation events. ϕ8 ranges between 0.01 and 0.1 for ACE in the 180-200 °C interval and between 0.1 and 0.4 for BMI in the 210-240 °C one.
