What is a key characteristic of fibre-reinforced composites?

Fibre-reinforced composites are known for their ability to enhance certain properties compared to traditional materials. A key characteristic of these composites is their resistance to corrosion. This property makes them particularly attractive for a variety of applications, especially in environments that would typically cause metals and other materials to degrade. The materials used in fibre-reinforced composites, such as glass or carbon fibres, combined with a resin matrix, create a structure that can withstand harsh conditions without deteriorating.

This characteristic primarily arises from the materials used; for instance, the resins in these composites are usually inherently resistant to chemical attacks, thus greatly extending the lifespan of the product. Resistance to corrosion not only helps maintain the integrity and performance of the composite but also reduces the need for frequent replacements or maintenance, contributing to cost-effectiveness over time.

Other characteristics mentioned, like being heavy and strong, exhibiting low strength to weight ratio, or being thermally conductive, do not generally apply to fibre-reinforced composites in a way that is advantageous. Fibre-reinforced composites are often designed to be lightweight while providing high strength, which is contrary to the notion of being heavy. They typically have a high strength-to-weight ratio, which is a critical benefit, making them widely used across various industries
