Composite materials testing
At INFINITIA Industrial Consulting we carry out tests on composite materials, essential for the evaluation of their mechanical, thermal and chemical properties. These tests allow us to ensure that the composite materials used in sectors such as automotive , the aeronautics and the construction maintain optimal performance under demanding operating conditions.
Thanks to the most advanced techniques and our team of experts, we select, optimize and validate composite materials in their industrial applications. We are here to boost your project!
What are composite materials?
The 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, as glass fibers, carbon either 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 these include glass fiber reinforced polymer (GFRP), carbon fiber reinforced polymer (CFRP) and 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.

Testing of composite materials: what it consists of
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 its 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 behavior 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, i.e. 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.
Importance of composite materials testing
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 defects manufacturing defects, like the 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.
Applications and examples of composite materials
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:
- Automotive industry: Composite materials are used in the manufacture of chassis, bodies and structural components due to their lightness and high strength. They are used for improve energy efficiency and vehicle performance, reducing fuel consumption and CO2 emissions. In addition, its corrosion resistance prolongs the life of vehicles and reduces maintenance costs.
- Aeronautical sector: In aircraft manufacturing, carbon fiber 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 maneuverability.
- Construction and infrastructure: 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.
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.
