What is the basic material of glass fiber reinforcement?The full name of glass fiber reinforcement is glass fiber reinforced composite material.The basic materials include unsaturated polyester resin,vinyl ester resin,epoxy resin,polyamide resin,etc.

　　Glass fiber reinforced material

　　The rapid development of glass fiber reinforcement has a great relationship with the material characteristics of glass fiber reinforcement.Compared with ordinary steel reinforcement,the physical properties and cost of glass fiber reinforcement are more superior.In terms of tensile strength,tensile modulus,and thermal insulation,It has great advantages in terms of performance and transportation operation cost.

　　1.In terms of construction period,compared with ordinary steel bars,glass fiber reinforcement is customized by the manufacturer.Since processing cannot be performed on site,it is necessary to control the size.Once the material is incorrectly cut,the construction period will be delayed.Its shape is directly customized,which reduces the processing steps of ordinary steel bars,and the lap joint method of binding replaces the linking process,which saves the production time of the rib cage.

　　2.In terms of construction difficulty,the bending resistance and shear resistance of glass fiber reinforcement are much different from those of ordinary steel bars and their weight is lighter.Therefore,the stability of the reinforcement cage lifting,lowering,and pouring engineering is not as good as that of ordinary steel cages.Special circumstances such as loose cages,stuck cages,and floating,need to be paid attention to in the production and hoisting of the rib cage.

　　Glass fiber reinforcement has been widely used in coal mine roadway support,deep foundation pit slope support,continuous wall,supporting pile reinforcement,and shield machine access and exit end well enclosure structures.Many actual cases have proved that glass fiber reinforcement has a higher cost performance,significant technical,economic,and social benefits,and has a good prospect for promotion and application.
