Fiberglass (FRB) ,also known as GFRP, has high strengh, mixing it with polyresin, can develop all kinds of shapes hard products, can bear pulling force ,also can bend over, mulitple advantanges like corrosion preventive, electric insulation, heat insulation ect.
Light and strong
relative density is between 1.5-2.0,only 1/4 to 1/5 of carbon steel,but the pulling strengh is very clost to carbon steel,some even higher ,can meet more than 400 Mpa
To air, water, common acid , alkali,salt ,fiberglass have very good resistivity
Fiberglass has 1.25~1.67kJ/(m·h·K),only 1/100 to 1/1000 of metal ,under normal room temperature,makes it a very good thermal insulating material
