Introduction to Composite Materials and Their Properties

Quick summary

Discover the unique properties of composite materials with CFI and learn why they are a popular choice for various industries.

A growing number of sectors are utilising composite materials and their properties because of their distinctive qualities and adaptability. They are synthetic materials with unique physical or chemical properties created from two or more different components. These components are mixed to produce a new substance with unique properties not found in the constituent parts.

Our goal at Composites Fibreglass International is to inform and educate our clients about the advantages and features of these materials. In Australia, we are a significant supplier of composite materials, with our process of educating and providing our clients with the ideal materials for their specific project being one of the best in Australia. In this post, we’ll give you an overview of composite materials and their characteristics so you can see why they’re a popular choice across a number of industries.

Composite Materials and Their Properties

One of the most significant advantages of composite materials is their ability to exhibit a combination of properties that are not present in any individual material. The following are some of the properties that make composite materials a popular choice:


Due to their excellent strength-to-weight ratio, composite materials are the best option for applications where weight reduction is crucial. They are frequently employed, for instance, in the aerospace sector when a robust yet lightweight construction is needed.


Due to their superior stiffness, composite materials are perfect for applications where load-bearing capability is crucial. For instance, they are employed in the construction sector to erect bridges and other buildings.


Since composite materials are so strong and resistant to wear and strain, they are a fantastic choice for situations where durability is essential. They are used, for example, in the marine industry where manufacturing vessels necessitates exposure to harsh weather.

Corrosion resistance

Composite materials are the ideal choice in situations when exposure to corrosive elements is frequent due to their excellent corrosion resistance. They are used, for instance, in the chemical industry for storage tanks and other constructions.

Electromagnetic neutrality

Composite materials are the best option for applications where electromagnetic compatibility is crucial since they do not interfere with electromagnetic fields. They are utilised, for instance, in the aerospace sector to build satellites and other space-based constructions.


Classification of Composite Materials

Composite materials can be classified based on the type of reinforcement and the matrix material used. The following are the most common classifications of composite materials:

Fibre-reinforced composites

These are composite materials where the reinforcement is in the form of fibres, such as glass, carbon or aramid fibres. The matrix material is typically a polymer, such as polyester, epoxy or polypropylene.

Particulate-reinforced composites

These are composite materials where the reinforcement is in the form of particulate material, such as ceramic or metal powders. The matrix material is typically a polymer.

Laminate composites

These are composite materials where multiple layers of reinforcement and matrix material are combined to create a layered structure.
