Product Data Sheet powerRibs Art. No. 5019 powerRibs Art. No. 5019 0°/90° Product description powerRibs, suitable for manufacturing fiber reinforced composite products with high performance and low environmental impact. This special reinforcement fabric is used to create a rib structure on one surface of the composite layer, significantly increasing the flexural stiffness and damping properties of thin composite shells with little additional weight. Fabric construction Fibre type: Flax (EU) Construction: 0°/90° Fibre tex: 1500 TEX Fabric weight: 215 gsm +/- 5% Architecture: Grid-like fabric with 14 mm mesh size Measurements Standard roll length: 50 m Mechanical composite properties Due to the discontinuous 3D structure, the mechanical properties of the powerRibs cannot be described in a generic way. The mechanical properties of powerRibs applied to a base layer can be represented by an equivalent homogeneous layer added to the laminate. The equivalent layer represents the "smeared" effect of the powerRibs over the part's surface. Note that the equivalent modulus is not identical in both in-plane directions. This is due to the ribs being bonded flat to the base in one direction. However, in the other direction the ribs have to "travel" over the flat ribs at each of their intersections (see modeling FE & 3D guide for illustration). Due to its grid structure with big tough yarns, powerRibs provides a very high damage tolerance to the part, also ensuring that it stays in one part even when crashed.

Product Data Sheet powerRibs Art. No. 5019 Ecological aspects Important facts Compared to carbon fibre reinforced plastics, powerRibs composite material (flax fibre reinforced plastics) has significantly lower environmental impact due to its weight advantages and lower material input. Water usage, CO2 footprint and embodied energy, is about 85% lower while using flax fibre reinforced plastics. Water usage for composites with Carbon fibres Carbon fibres Processing guidelines The principle of powerRibs is to create a rib structure on the surface of the composite part. Therefore it only works...
