Carbon Fiber Fabric for Column Wrapping Guide

Carbon Fiber Fabric for Column WrappingnnColumn confinement with carbon fiber fabric is the standard seismic retrofit method worldwide. Selecting the right fabric weight is critical.nn## Weight Selectionnn200g: single-layer on lightly damaged columns.n300g: most common - 2-3 layers for standard retrofit.n450-530g: heavy-duty columns, fewer layers needed.n600g: massive piers, flat surfaces only.nn## Design ConsiderationsnnFor a 400x400mm column: 2-3 layers of 300g fabric increases axial capacity 25-40%.nCorner radius must be minimum 20mm - sharp corners puncture the fabric.nn## FAQnnUnidirectional or bidirectional? Unidirectional for column confinement (hoop direction). Bidirectional for irregular shapes.nnView carbon fiber fabrics | Contact us
