Thermal insulation door stop materials typically used in low-temperature applications such as pipelines for transporting liquid natural gas can become brittle and are therefore susceptible to impact damage.New feather-fibre biomaterials developed in this work have extremely low thermal conductivity but retain high impact resistance at low-temperatures.The experiments reported demonstrate the improved Brooches impact resistance of feather fibre biomaterials compared to foamed nitrile rubber.The microstructural characteristics of feather-fibre biomaterials that allow them to be used as impact resistant thermal insulation at low-temperatures are discussed.
