Research on Dynamic Mechanical Properties of Poly(m-Phenyleneisophthalamide) Paper
The dynamic mechanical properties of PMIA-Pulp applied paper were investigated. At the same time, the dynamic mechanical properties of DuPont T410 paper were compared. Measurements of the dynamic mechanical properties were carried out on samples of low crystallinity and low orientation over a temperature range from 20°C to +500°C, at a frequency of 110 Hz, at a heating rate of 3°C/min. As the temperature from low to high, three different mechanical states with glassy state, rubber state and fluid state were appeared on DMA temperature curve, it responded the different mode of molecular motion. Storage modulus and glass transition peak of DuPont T410 paper were higher than the self-made applied paper. It means DuPont T410 Paper had a high resistance to external forces and deformation, as well as a good rigidity. Molecular chain freedom movement was difficult and the energy required to move relatively larger.
