This corresponds to about 150,000 times the weight of a fruit fly. Experiments on the high tensile strength of these fibres have revealed their extreme toughness.

A single fibre with a diameter of about 40,000 nanometres consists of up to 4,000 ultra-thin fibrils. These fibrils are linked by small amounts of an additive. Three-dimensional X-ray images show that the fibrils within the fibre are almost always arranged in the same longitudinal direction.<\/p>\n<p>Three-dimensional X-ray images show that the fibrils within the fibre are almost always arranged in the same longitudinal direction.
