What do spiders fear most? 2. The value of spiders
Spider silk is expected to be used to make high-strength materials.
Experts from the Institute of Gene Biology of the Russian Academy of Sciences are actively studying the use of spider silk to make high-strength materials.
There is a cluster of spinnerets behind the spider's abdomen, which passes through the silk glands in the body. Protein mucus secreted by this gland can condense into extremely strong spider silk in the air.
According to reports, experts from the Institute of Gene Biology of the Russian Academy of Sciences found that the hardness of this material is 9 times higher than that of steel with the same thickness, and the elasticity is 2 times higher than that of other most elastic synthetic materials.
Experts believe that after further processing, the spider silk material can be used to make light body armor, parachutes, protective materials for weapons and equipment, wheel tires, plastic surgery appliances and high-strength fishing nets.
