Fiberglass profiles as an alternative to aluminium


Fiberglass(FRP) profiles offer many of the advantages of aluminum and other traditional materials. Composites are being used by many industries to improve the design process, and end products and polymer composites are often replacing traditional materials such as aluminum. This article will outline some of the benefits of using fiberglass profiles as an aluminum replacement.

Fiberglass profiles

Fiberglass profiles with a high strength-to-weight ratio

One of the main reasons for using fiberglass profiles as an aluminum replacement is their high strength-to-weight ratio. Fiberglass profiles are lighter while also being stronger and stiffer, leading automotive engineers to use composites to reduce vehicle weight while improving crash safety. Because fiberglass profiles are made of multi-layer laminates, they absorb more energy than steel or aluminum.

Fiberglass profiles are very durable

An advantage of fiberglass profiles and aluminum is that they do not rust. However, fiberglass profiles are seen as a good alternative to aluminum because aluminum corrodes and polymer composites do not. Their high dimensional stability means they can hold their shape in cold and hot environments. This means they are excellent materials for outdoor structures such as wind turbine blades or building structures. Since fiberglass profiles do not corrode, they are easier and less expensive to maintain, resulting in long-term stability.

Fiberglass profiles are a safer alternative to aluminum

Fiberglass profiles do not conduct electricity, unlike aluminum which is dangerous in high-voltage areas. Composites are less susceptible to shocks, while aluminum is a low-strength metal that dents, breaks, or deforms easily.

Fiberglass profiles are more cost-effective in the long run

Although aluminum is a low-cost material and easy to install, its lack of durability necessitates more frequent repairs and replacements. This means that fiberglass profiles are more cost-effective in the long run.

Aluminum is an abundant element in the earth’s crust, so it is readily available. Its combination of features means it is versatile and therefore popular. However, aluminum should not be used in applications using hydrochloric acid, sulfuric acid, chlorine, and some other compounds. This means that aluminum is not suitable for sewage treatment facilities and some outdoor structures that are exposed to the elements.

Fiberglass profiles are resistant to inorganic and organic compounds, including all alkaline and acidic environments where aluminum cannot be used.
