GBTECH TORAYCA™ BT70-30 carbon-glass hybrid fabric is a bi-directional woven fabric combining carbon fiber and glass fiber in a checkerboard pattern. The carbon fiber yarns in both warp and weft are T700SC-12000-50C. The fabric is lock-stitched with glass fiber yarn and heat-set with polyamide. It is typically supplied as dry woven fabric for resin impregnation.
The BT70-30 has a higher carbon fiber areal weight than BT70-20, with 150 g/m² in both warp and weft. This makes it suitable for structural reinforcement applications requiring higher carbon fiber content per layer.

Potential uses include building and civil engineering concrete structure reinforcement, structural strengthening, and composite structural members. These are design directions, not certified load-bearing applications.
Carbon fiber is electrically conductive. Use appropriate dust control and personal protection during cutting and handling. Protect nearby electronics from conductive dust.
Confirm resin compatibility, lay-up orientation and cure schedule before production.
What is the difference between BT70-20 and BT70-30?
BT70-30 has a higher carbon fiber areal weight (150 g/m² vs 100 g/m²) and a greater design thickness (0.083 mm vs 0.056 mm).
What is the role of the polyamide heat-set?
The polyamide heat-set helps stabilize the fabric structure and the glass fiber lock-stitch along the selvedge.
What should I confirm before ordering?
Confirm roll length, width, quantity, resin compatibility, application standard and delivery country.
Request a quotation with the product number, required quantity, roll length, width, resin requirements and delivery country. Confirm pricing, packaging, availability and lead time with GBTECH before ordering.
