Mechanics of entangled fibers

When long, flexible fibers are densely packed, they form cohesive structures, such as those found in bird’s nests, cotton balls, or fibrous insulation materials. These peculiar granular assemblies exhibit complex mechanical behaviors: they can be compacted and sustain tensile stress, despite the absence of adhesive bonds. Through experiments on model materials and discrete-element simulations, we investigate the interplay between elasticity and friction that governs the mechanics of entangled, non-bonded fiber networks.
