300gsm vs 600gsm Biaxial Carbon NCF Selection Guide in one minute.
Choose between 300gsm and 600gsm biaxial carbon NCF from the laminate schedule, ply count, handling target and validated resin process. The heavier format can build thickness with fewer plies, while the lighter format can provide finer ply-by-ply control. Neither choice is automatically better for every part.

What the terms mean.
Biaxial carbon NCF places carbon fiber layers in two specified directions and holds them together with stitching. FRP HOME currently publishes verified English TDS files for 300gsm biaxial formats and a 600gsm balanced +45°/-45° format; the order specification still controls the supplied construction.
Key differences for material selection.
| Selection point | 300gsm biaxial NCF | 600gsm biaxial NCF |
|---|---|---|
| Laminate build | Finer ply increments | More reinforcement per ply |
| Handling review | More plies may be required | Fewer plies may be possible |
| Verified document scope | +45°/-45° and 0°/90° constructions | Balanced +45°/-45°, 1270 mm x 50 m reference |
| Process decision | Validate the complete stack | Validate the complete stack |
| RFQ priority | Direction, width, roll and stitch | Direction, width, roll and stitch |
How engineers and buyers should choose.
Start from the engineering laminate schedule and required fiber directions.
Compare total ply count, cutting plan and placement time rather than areal weight alone.
Confirm stitching, width, roll length, resin process and trial quantity before production.
Use the downloadable English TDS as a product reference, then confirm the final order specification and batch documents.
Where this comparison matters.
Typical values to confirm.
| Specification | Typical options |
|---|---|
| Verified formats | 300gsm biaxial and 600gsm +45°/-45° biaxial NCF |
| Fiber directions | 0°/90° or +45°/-45° according to confirmed construction |
| Width and roll | Confirm against the selected TDS and quotation |
| Resin process | Customer process trial and compatibility review required |

Common technical questions.
Is 600gsm biaxial NCF stronger than 300gsm NCF?
Areal weight alone does not determine final laminate strength. Fiber grade, orientation, ply count, resin, processing and laminate design all affect performance.
Can 300gsm and 600gsm NCF be used in one laminate?
They may be combined when the laminate design calls for it, but the full stack and resin process should be validated by the customer's technical team.
