Strengthening the interface between individual aramid fibers and polymer at room and elevated temperatures

Composites reinforced by aramid fibers may suffer poor interface interactions during mechanical loading due to the smooth and chemically inert surface of the fibers. Plasma treatment is usually employed to functionalize and roughen surface of the fibers, leading to strengthening of the interface between the fibers and polymer matrix. Unfortunately, once the composite is exposed to elevated temperatures, the interface shear strength (IFSS) will...
