The predominant structural damage for various heating rates is verified to only occur in the IF. α-helices in three cortical components are homogenously damaged on chemically damaged fibres. However, heating rates yield a homogenous effect on disulfide linkages of para- and ortho- cortex, regardless of any previous oxidation treatment.
