Abstract Scope |
Cellulose nanocrystal is a type of naturally abundant biomaterial. Due to its high surface-to-volume ratio, strength, elastic modulus, and nanoscale size, it is an excellent candidate for enhancing the interphase strength of polymer matrix-based composites. Recently, there has been some experimental evidence suggesting successful applications of cellulose nanocrystals in composites. However, the limited spatial resolution in experimental techniques makes it challenging to directly observe or measure interphase properties. Thus, molecular dynamics simulation becomes a preferred tool to bridge this knowledge gap. This study examines the effect of two modifications on the interphase strength of glass fiber-reinforced epoxy composites: adding saline sizing as a baseline and incorporating additional cellulose nanocrystals at the interphase. The simulations provide in-depth insight into the interphase strength and nanoscale evidence to explain the enhanced interphase strength resulting from the two modifications. |
