Multiscale Modeling of Interphase Properties in Fiber-Reinforced Polymer Composites
Quick fact
The interphase in a fiber-reinforced composite is typically only 10–100 nanometers thick, yet it can govern the composite's strength, toughness, and durability. Multiscale modeling links this nanoscale region to the macroscale behavior of the entire part.
Why this is interesting
You’ve seen how strong composites are, but did you know that the tiny region between the fiber and the polymer—barely a few nanometers—often controls their strength? How do engineers predict the properties of a region too small to see?
