What are composite materials?
What is it?
Composite materials are formed by the combination of two or more components with different physical and chemical properties, which when joined together generate a new material with superior characteristics to those of its individual components. On the one hand, there is the matrix, which acts as a base material; as well as the reinforcement, such as glass fibres, carbon or aramid. The matrix provides shape and cohesion, while the reinforcement provides strength and rigidity.
This synergy results in materials with high mechanical strength, low density and excellent performance under extreme conditions, making them ideal for applications in industries such as automotive and aeronautics.
Some examples of composite materials include glass fibre reinforced polymer (GFRP), carbon fibre reinforced polymer (CFRP) and the ceramic composites used in aerospace applications. These materials are chosen for their ability to withstand high stresses and their resistance to fatigue and corrosion, making them the preferred choice for structural components.
Importance of composite materials testing
Benefits
Composite material testing is essential to ensure that materials used in structural and high-performance components meet the specific requirements of each application. It helps us detect potential manufacturing defects, such as delamination, the formation of microcracks or the presence of voids, which can compromise the structural integrity of the material. In addition, they provide essential data for product design and engineering, facilitating the selection of materials and the optimization of manufacturing processes.
For example, in the aeronautical industry, these tests are a guarantee of the resistance of composite materials. They help ensure that their components are able to withstand the extreme loads and conditions to which they will be exposed during flight, such as sudden changes in temperature, pressure and vibrations.
They also allow engineers to assess the behaviour of composite materials under harsh environmental conditions such as exposure to UV radiation, moisture and chemicals, crucial for applications in the construction and infrastructure sectors. The information gained from these tests is vital for developing products that not only meet performance expectations, but also offer long life and reduced maintenance.

Testing of composite materials: what it consists of
Types
Composite materials testing is a set of tests and analyses designed to determine the tensile, compressive, flexural and shear strength of materials, as well as their fatigue behaviour and resistance to adverse environmental conditions.
Common tests include:
Tensile test
A controlled longitudinal force is applied to the material to measure its strength and elongation up to the breaking point. This test is crucial to understanding the elastic and plastic behaviour of the composite, as well as its modulus of elasticity and breaking limit. The data obtained are vital for applications where the material will be subjected to stretching stresses, such as in structural components and parts subjected to dynamic loading.
Compression test
It evaluates the material’s ability to withstand compressive loads, that is, forces that tend to reduce its size. This is undoubtedly essential for components that must withstand high pressures without deforming, such as structural pillars or vehicle casings. It allows the yield point and maximum strength of the material to be determined, so that the final product meets safety and functionality requirements.
Bending test
The material is subjected to a load perpendicular to its longitudinal axis to measure its flexural strength. This test thus provides information on the material’s stiffness and ability to withstand deformations without fracturing. It is especially useful in construction and automotive applications, where parts are exposed to repetitive bending forces, such as in beams and chassis.
Fatigue test
Determines the durability of the material under cyclic loads, simulating the real conditions of use to which it will be exposed during its useful life. It is essential to predict the useful life of the component and avoid premature failures in critical structures. The results allow the design of the composite material to be optimized, ensuring that it maintains its structural integrity even after long periods of use.
Applications and examples of composite materials
Sectors
Composite materials have a wide variety of applications due to their unique combination of properties such as high strength, low weight and corrosion resistance. Some examples of composite materials and their applications include:
It is important to note that each application requires specific characterization of the materials to ensure that they meet the technical and regulatory requirements of the sector. This is how we achieve final products that are not only efficient and safe, but also profitable and sustainable in the long term.
Automotive industry: lighter vehicles without losing strength
Composite materials are used in the manufacture of chassis, bodies and structural components due to their lightness and high strength. They are used to improve energy efficiency and vehicle performance, reducing fuel consumption and CO2 emissions. In addition, their corrosion resistance prolongs the life of vehicles and reduces maintenance costs.
- Measure the modulus of elasticity and breaking limit of parts subjected to dynamic loading through tensile testing.
- Confirm through compression testing that casings and structural pillars withstand high pressures without deforming.
- Anticipate through fatigue testing the service life of components exposed to cyclic loads throughout their working life.
Every automotive application requires specific characterization to demonstrate compliance with the technical and regulatory requirements of the sector.
Aeronautical sector: lighter and stronger structures
In aircraft manufacturing, carbon fibre composites are essential for reducing the weight and increasing the strength of structures such as wings and fuselages. This not only improves fuel efficiency, but also increases the load capacity and durability of aircraft. Composite materials also allow for advanced aerodynamic design, which reduces air resistance and improves aircraft stability and manoeuvrability.
- Verify that components withstand the extreme loads and conditions of flight, with sudden changes in temperature, pressure and vibration.
- Detect delamination, microcracks and the presence of voids that compromise the structural integrity of the part.
- Assess the flexural strength of elements such as spars and panels subjected to repetitive stresses.
In a regulated sector, the traceability of the test forms part of the technical documentation required for the component.
Construction and infrastructure: behaviour against the environment
Composite materials are used in the manufacture of structural panels and reinforcements due to their high resistance to corrosion and mechanical loads. This is especially useful in structures exposed to aggressive environments, such as bridges, offshore platforms and buildings located in coastal areas. In addition, composites offer advantages such as greater design flexibility and faster and easier installation compared to traditional materials.
- Assess behaviour against UV radiation, moisture and chemical agents in structures exposed to the weather.
- Check the flexural strength of beams and panels exposed to repetitive loads.
- Confirm corrosion resistance in aggressive environments such as offshore platforms or coastal construction.
The aim is long service life and reduced maintenance, which is where the composite pays back the investment against the traditional material.
