Fabric construction Fibre type: Flax (EU) Construction: -457+45° Fibre tex: 1500 TEX Fabric weight: 215 gsm +/- 5% Architecture: Grid-like fabric with 14 mm mesh size Measurements Standard roll length: 50 m Product Data Sheet powerRibs Art No. 5005 Product description powerRibs fabric is designed for manufacturing fiber reinforced composite products with high performance and low environmental impact This special fabric creates a rib structure on one surface of the composite layer, thus significantly stiffening thin composite shells with little additional weight The fabric is especially meant to reinforce tubular structures by increasing hoop strength. 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 guidefor 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. 5005 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.
