文摘
- •
Enthalpy relaxation depends on cooling rate and reinforcement content.
- •
Enthalpy relaxation is independent of the gelation temperature.
- •
Shrinkage upon reheating due to stress release that counteracts enthalpy recovery.
- •
Relaxed matrices shrink more during reheating than abruptly cooled samples.
