Elastic fibers made of the protein elastin has a coiled structure which allows it to stretch and recoil. Fibers can stretch up to 150 percent of their relaxed state length without breaking.

Collagen Fibers, made up of fibrous protein, which are bundled together into thick collagen fibers. Collagen fibers are extremely tough and provides high tensile strength (which provides resistant property of tendons) Stress tests have show collagen fibers to be stronger than steel fibers of the same size.....EB

I think you are refering to a type of protein called ' elastin '. It is man made in the sense that it naturally occurs in our bodies as elastic fibers.

Spindle fiber is made of clusters of aggregated microtubules. The spindle fibers will form at opposite poles of a cell during the prophase in mitosis.

The matrix of connective tissue is composed of collagen, reticular, and elastic fibers embedded in ground substance (typically composed of water with stabilizing proteins). The fibers are made by fibroblasts and the most abundant in the body is collagen, while the least abundant is elastic.
Elastic is typically made of rubber or latex materials that can stretch and return to their original shape. These materials are combined with other fibers, such as polyester or cotton, to create various elastic products like bands, cords, and threads.
