Product Data Sheet powerRibs Art No. 5020 powerRibs Art. No. 5020 0790° Product description powerRibs material is designed for manufacturing fiber reinforced composite products with high performance and low environmental impact This special fabric creates 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: 0790° Fibre tex: 3000 TEX Fabric weight: 215 gsm +/- 5% Architecture: Grid-like fabric with 28 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 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.

Important facts Product Data Sheet powerRibs Art. No. 5020 Compared to carbon fibre reinforced plastics, powerRibs composite material (flaxfibre reinforced plastics) has significantly lower environmental impact due to its weight advantages and lower material input. Water usage, CCpfootprint and embodied energy, is about 85% lower while using flax fibre reinforced plastics. Water usage • PowerRibs are well compatible with epoxy and polyester. • Sensitive to humidity: dry fabric before use (example: I05°C, I 5 minutes). • The key factor to optimize the effect of the powerRibs is to create a...
