چکیده انگلیسی


- Epoxy nanocomposites fabricated at different CNFs filler loadings by hand lay-up.
- Addition of CNFs improves thermal stability and char content of epoxy composites.
- E', E” and Tg of epoxy composites increases remarkably by incorporating CNFs.
- Noticeable decrease in Tan δ by adding CNFs with respect to epoxy composites.
- 0.75% CNFs filler loading seems most effective and best among 0.5% and 1% loading.

The current study presents about the effect of cellulose nanofibers (CNFs) filler on the thermal and dynamic mechanical analysis (DMA) of epoxy composites as a function of temperature. In this study hand lay-up method was used to fabricate CNF reinforced Epoxy nanocomposites with CNF loading of 0.5%, 0.75%, and 1% into epoxy resin. The obtained thermal and DMA results illustrates that thermal stability, char content, storage modulus (E'), loss modulus (E”) and glass transition temperature (Tg) increases for all CNF/epoxy nanocomposites compared to the pure epoxy. Thermal results revealed that 0.75% offers superior resistance or stability towards heat compared to its counterparts. In addition, 0.75% CNF/epoxy nanocomposites confers highest value of storage modulus as compared to 0.5% and 1% filler loading. Hence, it is concluded that 0.75% CNFs loading is the minimal to enhance both thermal and dynamic mechanical properties of the epoxy composites and can be utilized for advance material applications where thermal stability along with renewability are prime requirements.
