aBased on the tanδ peak temperature of DMA measured at a frequency of 1 Hz and a heating rate of 2 °C/min. Values in bracket indicate Tg values for the bulk thermosets of the second component determined by DMA.
bBased on the tensile test at the rate of 1 mm/min and room temperature. The modulus was determined in the strain range of 0.05–0.25%
cEvaluated based on an area below each stress–strain curve. The toughness values of M120G was 4.4 ± 0.77 kJ/m2.
d The E’ values of CNP-T6/A6 were 1680, 309, and 8.9 MPa at 25, 100, and 180 °C, respectively, determined by DMA.
eThe E’ values of CNP-T3/A6 were 240 and 17.5 MPa at 80 and 180 °C, respectively, determined by DMA.
fM120A was used instead of M120G.
gThe E’ values of CNP-P6 were 3170, 324, and 23.1 MPa at ‒80, 0, and 160 °C, respectively, determined by DMA.
hThe E’ values of CNP-P6/A1-20 were 5530, 839, and 29.6 MPa at ‒80, 0, and 160 °C, respectively, determined by DMA.
