Composite materials characterization

An integrated approach to maximizing the performance of your composite materials

TEC Eurolab is the testing laboratory that can support you for analysis and testing of composites

A composite material is a heterogeneous material consisting of two or more chemically distinct, insoluble and easily distinguishable phases. Depending on the relative amounts of the two phases, the geometry of the reinforcing elements (i.e., shape, size, distribution, and orientation) results in different composite material performance.

The use of composite materials in industry is going through a phase of steady growth, in very heterogeneous application sectors (aerospace, automotive, marine, sports…), which are strongly impacted by the development of new and increasingly high-performance material combinations.

TEC Eurolab is the technical partner that can support companies during all stages of the production process. Through an integrated approach it performs the characterization of composite materials that meet needs such as:

  • lightness
  • mechanical, fatigue and chemical resistance
  • absorption of impact energy
  • atmospheric aging
