GBTECH TORAYCA™ BT70-20 carbon-glass hybrid fabric is a bi-directional woven fabric combining carbon fiber and glass fiber in a checkerboard pattern. The dark squares are carbon fiber, and the light squares are glass fiber. The fabric is lock-stitched with glass fiber yarn along the selvedge. It is typically supplied as dry woven fabric for resin impregnation and structural reinforcement.
The BT70-20 uses T700SC carbon fiber. Its balanced warp and weft carbon fiber areal weight of 100 g/m² makes it suitable for civil engineering and concrete structure reinforcement.

Potential uses include structural reinforcement in building and civil engineering, concrete structure repair and 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 carbon fiber and glass fiber in this fabric?
The dark squares are carbon fiber, providing strength and stiffness. The light squares are glass fiber, contributing to durability and cost efficiency.
Is this fabric suitable for concrete structure reinforcement?
It is commonly used in civil engineering reinforcement applications. Confirm the design requirements, resin system and application standard before use.
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.
