Based on aluminum honeycomb technology, the AXAC frontal offset barrier (developed under EEVC-WG11) is used by car manufacturers and test laboratories worldwide for the assessment of motor vehicle passenger protection in frontal offset collisions.
The frontal offset impact replicates a collision with another vehicle. In this test, 40% of the test vehicle on the driver’s side initially makes contact with a crushable aluminum honeycomb barrier at the impact speed defined by the standards requirements.

A complete testing procedure for certification of aluminum honeycomb is performed in-house according to IIHS Side Impact Crashworthiness Evaluation 2.0, Moving Deformable Barrier Specification, version 2.0 from May 2020, and in accordance with the procedure defined in NHTSA TP-214D. The aluminum honeycomb blocks are processed such that the force deflection curve, when statically crushed, is within the corridors defined for each block.
The AXAC Offset Deformable Barrier is certified for frontal NCAP tests such as:
