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, naval or renewable energies.

As a result, manufacturers in these industries use an increasing amount and variety of compounds 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. 

Our solution

Applus+ Laboratories has NADCAP accredited laboratories for composite materials testing and has a team with expertise in composites and their applications in leading industries.

Our composite materials characterization and testing service covers:

  • Characterization and/or qualification plan design
  • Manufacturing of specimens, coupons and prototypes
  • Test piece design and manufacture
  • Test tool design and manufacture
  • Material behavior virtual simulations
  • Non-destructive tests NDT
  • Physical, chemical, and mechanical (static and dynamic) tests
  • Aging, thermal shock and thermal fatigue tests
  • Online and real time monitoring of the test: Applusetesting
  • Results evaluation
  • Helps decision making in material selection
  • Support in R&D+I programs
  • Manufacturing quality control

Our technical team performs standard tests (EN, ISO, ASTM, 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:

  • Polymer matrix composites
  • Reinforced plastics
