How to Choose Carbon Fiber Fabric by GSM in one minute.
Carbon fiber fabric GSM, or areal weight, should be chosen by target laminate thickness, ply count, handling, surface appearance and structural requirement.
What the terms mean.
GSM means grams per square meter. In carbon fabric sourcing it describes fabric areal weight before resin impregnation.
Key differences for material selection.
| GSM range | Typical use | Notes |
|---|---|---|
| 3K 200 g/m² documented | Visible parts and general CFRP surfaces | Published FRP HOME twill-fabric TDS |
| Other woven GSM | Project-specific reinforcement | Requires matching construction data and order review |
| UD 300 g/m² documented | Directional reinforcement | Published FRP HOME UD-fabric TDS |
| NCF 300 / 600 g/m² documented | Multidirectional reinforcement | Published FRP HOME biaxial NCF TDS files |
How engineers and buyers should choose.
Start from the laminate schedule, visible-surface target and required fiber direction.
Use the published 3K 200 g/m² twill record as a documented reference for visible woven applications.
Request matching product data for any other GSM, tow, weave or construction.
Confirm resin process because heavier fabrics may wet out differently.
Where this comparison matters.
Typical values to confirm.
| Specification | Typical options |
|---|---|
| Tow | 1K / 3K / 6K / 12K |
| Weave | Plain / twill / satin / jacquard / spread tow |
| Width | 1000 / 1270 / 1500 mm or custom |
| Documents | TDS / SDS / COA by request |

Common technical questions.
Does higher GSM always mean stronger?
Higher GSM adds more fiber per area, but final strength depends on fiber grade, layup, resin, process and load direction.
What GSM is common for 3K twill?
FRP HOME currently publishes a TDS for 3K 200 g/m² twill fabric. Other weights require a matching product record and order confirmation.
