The composites were subjected to thermal treatment for different
durations and at different temperatures, in order to find the condition
with the greatest possible removal of epoxy resin without
causing any pronounced thermal degradation in the fibers. These
tests were monitored by SEM and FTIR. In addition, important parameters
such as shorter heating time with less expenditure of
energy were also taken into account in order to select the ideal
condition. The experimental conditions of the degradation of the
composites are listed in Table 2. The C letters correspond to the
composite epoxy resin denomination, while the intermediate
numbers describe the temperature of the test and the last digits
describe the degradation time applied
