What is the density of fiberglass reinforced plastic?
The density of fiberglass reinforced plastic (FRP) is a key material property that greatly influences the performance, strength, and durability of the material. It is a composite material made by combining a polymer resin (such as polyester, vinyl ester, or epoxy) with reinforcing fibers (typically glass, carbon, or aramid). What is the density of fiberglass reinforced plastic typically falls within the range of 1,500 to 2,000 kg/m³, though this can vary based on the specific resin and fiber types used in the composite. The density of FRP plays a crucial role in determining its strength-to-weight ratio, making it an ideal choice for applications where both strength and lightweight properties are important.
The resin used in the manufacturing process is a significant factor in determining the density of FRP. Resins like polyester, vinyl ester, and epoxy have different molecular structures that can impact the final density of the material.
