Storage modulus E′ and Tg obtained by means of dynamic Mechanical Analysis (DMA) and differential Scanning Calorimetry (DSC) measurements on unfilled and fiber-reinforced (both carbon and glass) blends.
| Property | B33 | B50 | B33G5 | B50C5 |
|---|---|---|---|---|
| Storage modulus E′ (GPa) 1 | 3.15 ± 1.0 | 3.15 ± 0.6 | 4.30 ± 0.3 | 5.18 ± 0.6 |
| Theoretical prediction of E′ (GPa) 2 | - | - | 4.65 | 5.58 |
| Tg,DMA (°C) | 127 | 128 | 155 | 123 |
| Tg,DSC (°C) | 106 | 100 | 105 | 74 |
1 The reported values of storage modulus were obtained at 25 °C; 2 Theoretical prediction as calculated by using the Halpin-Tsai model.
