Composite materials testing

Characterization of composite materials behavior for their optimum use in products and components
The incorporation of composite materials allows the manufacturing of lighter and more resistant products and components, two key parameters for improving competitiveness and differentiation in sectors such as aerospace, defense, automotive, railway or renewable energies.
As a result, manufacturers in these industries use an increasing amount and variety of composites in their products. Characterizing these materials will allow their configuration to be optimized during the design stage, choosing the most suitable manufacturing method for each application. 
Composite Materials Laboratories
Applus+ Laboratories has a network of  NADCAP and ISO/IEC 17025 accredited laboratories and an expert team in advanced composites and their applications in leading industries. We also have specific customer recognitions such as Airbus, Safran and Comac approvals for materials testing.
Our service scope covers:
Our technical team performs standard tests (EN, ISO, ASTM, GB and MIL-STD, among others) or tests designed according to the client's specific regulations (AITM, SP, GD, among others) for any type of application. We test both commonly used materials and materials for advanced applications such as polymer matrix composites, reinforced plastics, sandwich type materials (foam core, honeycomb core), carbon fiber composites, fiberglass composites
