What are the reasons that affect the strength of fiberglass chopped strand mat?
Fiberglass is a composite raw material. It has strong corrosion resistance, insulation and other advantages and is used in various fields. Generally, there are three main reasons that affect the strength of fiberglass chopped strand mat:First, the strength of fiberglass, the strength and stiffness of fiberglass directly affect the strength of chopped strand mat. The higher the tensile strength of the glass fiber, the greater the toughness, and the higher the tensile strength of the chopped strand mat produced.Second, the binder content. The production of Nanjing EFG fiberglass chopped strand mat needs to be produced strictly according to customer needs. When the fiber strength is determined, the strength of the chopped strand mat needs to be improved by the binder content. Generally speaking, the higher the binder content, the higher the tensile strength of the chopped strand mat.Third, the storage time. The storage time of fiberglass chopped strand mat still has some influence on its strength. After a long period of storage, the strength will decrease. This phenomenon is due to the aging of glass fiber and the chemicalization of adhesives. It is mainly caused by the erosion effect of moisture in the air on the fiberglass.
