Variable-modulus Smart Composites with respect to Frequency and Temperature |
| 초록 |
The variable modulus composite system with temperature and frequency was developed by incorporating fusible metal and inorganic particles in the epoxy matrix system. The storage modulus of composite specimen is decreased sharply due to phase transition of Sn-In particles at melting point imbedded in epoxy matrix. And then, reached the glass transition region, the storage modulus is decreased again, resulting the storage modulus of composite specimen seems to be like terraced shape. Moreover, the storage modulus master curve was obtained using modulus superposition analysis. The variation of activation energy and shift factor was identified at the phase transition of Sn-In particles. |
