West System G/Flex 650 Carbon Double bias means that the

Double bias means that the fibres are running on an angle (45°C) to the edge rather than parallel and perpendicular to the edge

This panel is NOT high grade perfect - there is occasionally some minor texture print through on the gloss white side

it won't clog up your equipment with uncured resin

If the repair needs reinforcing then do so prior to mixing resin

Commonly used in making lightweight water/chemical tanks and in making boat hulls

West System G/Flex 650 Carbon Double bias means that theG flex 650 has the ability to make structural bonds that can absorb the stresses of expansion, contraction, shock, and vibration. This epoxy is resilient and impact resistant. With a modulus of elasticity of 150,000 psi (WEST SYSTEM 105 Resin 205 Hardener has a modulus of elasticity of 450,000 psi), G flex is more flexible and can deflect further before breaking than WEST SYSTEM 105 205, while being much stiffer than typical adhesive sealants.
