Fiberglass specific weight: weight of 1 m³ and density
Fiberglass-reinforced plastic is a composite material consisting of glass-fiber filler, such as glass or quartz fibers, and a polymer binder. It combines relatively low weight with high specific strength, so it is used in construction, transport, electrical engineering, tanks, housings and other products.
Among the properties of fiberglass are low thermal conductivity, high specific strength, resistance to moisture, biological and atmospheric effects. It is also worth noting that fiberglass properties depend on the type of binder, reinforcement and production technology.
Various products are made from fiberglass: window, door and similar profiles, many products with high resistance to water and moisture, such as hot tubs, water attractions, boats, as well as various products for mechanical engineering and protection applications.
Fiberglass specific weight table
The table below contains average values for such indicators as the specific weight of fiberglass, its density and the weight of one cubic meter of fiberglass. This table will help perform the necessary calculations, including such a parameter as fiberglass weight.
| Material | Specific weight, g/cm³ | Weight of 1 m³, kg |
|---|---|---|
| Fiberglass | From 0.4 to 1.8 | From 400 to 1800 |
Specific weight calculations
For practical calculation of fiberglass mass, material density and the weight of one cubic meter are usually used. The values in the table are approximate: actual density depends on binder composition, reinforcement type and material grade.
The density of a material or substance is its mass, measured in kilograms, contained in one cubic meter. This parameter depends on many factors, such as temperature. Fiberglass density ranges from 1800 to 2000 kg/m³.
Frequently Asked Questions
How much does 1 m³ of fiberglass composite weigh?
The article gives an approximate range of 1800-2000 kg/m³. The exact value depends on resin, glass fiber type, reinforcement share and production technology.
Why is fiberglass density not constant?
Fiberglass is a composite, so weight changes with binder composition, glass fiber content, fillers and impregnation quality.
How do you calculate the weight of a fiberglass part?
Determine the part volume and multiply it by material density. For critical parts, use the datasheet of the specific composite.
