As shown in Fig. 2, within the entire range of testing temperature,
the storage modulus of the SMP composites increases along
with the addition of CB content. At 90 C, the rubbery moduli of
these four samples (CB0-CB9) are 3.05 MPa, 4.45 MPa, 3.96 MPa and
9.8 MPa, respectively. Besides, it is seen that the Tg of the SMP
composites is also elevated with the incorporated CB. Compared
with the Tg of pure SMP (42.7 C), Tg of SMP composite with 9 wt%
CB is increased to 47.6 C
