The manufacturer of GRP rebar tells you that GRP is a composite material consisting of two parts: a matrix and a reinforcement. The matrix of GRP material is resin, which has a bonding effect, and the percentage of the total volume is 30%-40%. Resin is a kind of thermosetting plastic, including epoxy (EP), phenolic resin (PF), etc. At the same time, resin is also an organic non-metallic material. The manufacturer of GRP rebar tells you that the reinforcement of the GRP material is glass fiber, which plays a role of reinforcement. Glass fiber is a kind of inorganic non-metal man-made inorganic fiber, such as glass fiber, carbon fiber, Kevlar fiber B, etc., which roughly accounts for 60% to 70% of the total volume. Therefore, GRP is a plastic-based composite material composed of organic non-metallic and inorganic non-metallic.

The manufacturer of GRP rebar tells you that GRP has good electrical insulation and bonding properties, high mechanical strength and heat resistance, spinnability, resistance to general acids, alkalis and organic solvents, and resistance to mold. The manufacturer of GRP rebar tells you that the molding shrinkage rate is small, and the volume shrinkage rate is 1%~5%. After adding the curing agent, it must be pressurized and heated for molding, and it can also be cured under contact pressure at room temperature.
The manufacturer of GRP rebar tells you that GRP has strong plasticity and is a composite material consisting of a matrix and a reinforcement. It is often used for decoration and decoration.
