How does fiberglass enhance?

- Sep 26, 2018 -

Glass fiber is an inorganic non-metallic material, which is fibrous glass. It is a very fine fiber made of molten glass. It has good insulation, heat resistance, corrosion resistance and high mechanical strength. It is mainly used as insulation material and Raw materials for FRP, etc.


One: the principle of glass fiber reinforcement


Since the connection between the glass fiber and the resin is inevitably transmitted to the glass fiber by the force acting on the molded article, the length of the glass fiber is fully utilized to enhance the resin.


Two: Factors affecting the strength of glass fiber:


1. Fiber diameter and length: the smaller the diameter, the smaller the length and the stronger the strength;


Chemical composition: The larger the alkali content (sodium oxide/potassium oxide), the smaller the strength, the worse the chemical stability and electrical insulation performance, except for hydrofluoric acid (HF), concentrated alkali (NaOH), concentrated phosphoric acid, Chemicals and organic solvents have good chemical stability.


2. Storage time: The longer the storage time, the lower the strength (the erosion of moisture in the air)


3. Applying load time: the longer the applied load time, the smaller the strength
