How does silane treatment affect the thermal stability of Cordia dichotoma fibers (CF)?

Label:chem

Topic
Thermal stability is a critical property for natural fibers used in composite materials, especially in applications requiring high-temperature resistance. Poor thermal stability can lead to degradation and reduced performance of the composite. Silane treatment has been shown to improve the thermal properties of natural fibers by enhancing their crystallinity and reducing amorphous components.
Answer
Silane treatment enhances the thermal stability of Cordia dichotoma fibers. The decomposition temperature of untreated fibers is 341°C, while silane-treated fibers decompose at 355°C. This increase in thermal stability is attributed to the improved crystallinity and reduced amorphous components (lignin and hemicellulose) in the treated fibers. The treated fibers also exhibit better resistance to thermal degradation, making them suitable for high-temperature composite applications.
