Summary of the effect of high temperatures on impact behaviour of fibre-reinforced composites.
| Fibre | Structure | Matrix | Temperature [°C] |
Properties Compared to Room Temperature | References |
|---|---|---|---|---|---|
| Carbon T300-3000 |
Orthotropic | Epoxy | 120 | Delamination area decreases with impact energy | [180] |
| Carbon | Orthotropic | PEEK | 120 | Delamination area increases, but matrix cracking decreases | [180] |
| Carbon | Quasi Isotropic | Epoxy | 150 | Very few delaminations are observed | [204] |
| Carbon | Woven | Polyethene-naphtholate | 100 | Low-impact resistance + enhanced toughness | [205] |
| Flax | Woven | Epoxy | 300 | Poor impact resistance due to fibre weakening | [206] |
| Glass | Woven | Epoxy | 300 | Increased absorption + maximum deflection | [206] |
| Jute | Woven | Unsaturated polyester | 75 | Low impact damage was observed at 30 °C and 50 °C, compared with 75 °C | [14] |
| Flax | Stacked sequence | Epoxy | 100 | Low impact damage was observed at 100 °C | [162] |
| Flax | Stacked sequence | Styrene polyester | 100 | Lower impact strength but increased tensile strength and flexural strength. | [209] |
