Biaxial ±45° Carbon Fibre Fabric 300 GSM
Product Code: SDF-FIB-B45-300
Biaxial ±45° Carbon Fibre Fabric 300 GSM provides ±45° reinforcement in one lay-up for laminates dominated by shear and torsional loads.
Why does it matter?
Nominal carbon areal weight is 300 g/m², while total product areal weight including stitching is 305 g/m². Nominal carbon GSM and total product GSM should not be confused in purchasing or laminate calculations.
When selecting
- Confirm load directions and the target stacking sequence.
- Assess the resin system, process and target fibre volume fraction together.
- Allow for the 127 cm standard width and roll length in the cutting plan.
- Use the current TDS on this page for final values.

Frequently Asked Questions
What does 300 GSM mean?
It is the total nominal areal weight of the carbon layers. Including polyester stitching, total TDS areal weight is 305 g/m² with a tolerance range of 289–321 g/m².
Which loads suit this fibre orientation?
Provides ±45° reinforcement in one lay-up for laminates dominated by shear and torsional loads. The final stacking sequence must be verified by engineering calculations and production trials.
Which composite processes can use this reinforcement?
It may be considered for resin infusion, vacuum bagging, RTM and suitable wet-lay-up processes. Resin wet-out and process compatibility must be confirmed by testing.
