Abstract
Described herein are articles and methods of making articles, including a transparent composite film having a fiber filler embedded in a polymer network and further including a hard coating. The polymer network of the film is a cured, cross-linked matrix. The hard coating is a cross-linked aromatic urethane acrylate oligomer and a photoinitiator and provides a flexible protective layer that maintains good hardness, puncture-resistance and scratch-resistance.
