How is artificial spider silk made
WebWhat is stronger than spider silk? Spider silk is considered to be one of the strongest materials in the natural world, but it does have its limitations. For example, the tensile strength of spider silk is around 1.3 gigapascals (GPa), whereas the tensile strength of synthetic materials such as Kevlar and Dyneema can reach up to 6 GPa. Web30 jul. 2024 · Spider silk is composed of protein and is biodegradable. Spider silk is more resistant to high temperatures. It exhibits thermal stability below 200°C and starts to turn yellow at above 300°C. Spider silk is resistant to low temperatures, and it still remains at minus 40°C. Elasticity, it hardens only at lower temperatures.
