Question: is spider silk stronger than carbon fiber?
Answer: Dragline silk is around 1.1 GPa. Depending on the specific alloy, this can be stronger than steel, which lies in the same range. But it is still beaten by Kevlar, which has a tensile strength of 3.0 – 3.6 GPa. ... Spider silk fibers are not as strong a Kevlar carbon fiber but they are tougher.
