PSA D41 1003 Compression Resistant (Lifting) Flexible Cell Materials

The PSA D41 1003 standard developed by the Peugeot automobile company describes a test method for determining the compression resistance of soft and semi-soft porous materials. This test method covers materials with a resilient grooved surface shape (alveolate) to reduce compressive strength.

Flexible cellular materials (honeycomb materials) are a lightweight core material for structural stiffening applications. This versatile material is widely used in the construction of aircraft components such as floors and interior panels. Other applications include railroad car doors and ceiling panels, marine curtains and furniture. This material is also an ideal material for energy absorption parts such as bumpers, fenders and lift shaft bases.

The most obvious use for flexible cell materials occurs in a variety of land vehicles. The most common applications are air routing for the engine fuel injection system, energy absorption in pillars and along the roofline for occupant protection, construction of crash test barriers, and energy absorption shielding structures in formula 1 race cars.

Stabilized compressive strength of these materials refers to the ultimate compressive strength loaded on the core. Normally for this test, the coatings are adhered to the honeycomb material (stabilized compression). Some flexible cell materials exhibit a linear initial stress-strain relationship, while some honeycomb materials exhibit a nonlinear relationship. This test is easy and fast to perform.

Flexible cell materials are a versatile material, usually composed of regular hexagonal cell structure and available in a wide variety of densities, configurations and sizes. It has a high strength-to-weight ratio, light weight and excellent environmental durability. The different types of raw materials used in making these materials are mainly aluminum, aramid, stainless steel and thermoplastic. In general, sandwich structures, energy absorbers, laminar flow controllers, sound reducers and dielectric materials are sought after in a wide variety of applications.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services for compression-resistant (lifting) flexible cell materials within the scope of PSA D41 1003 standard, with its trained and expert staff and advanced technological equipment.
