Choosing carbon fiber tow: 3K, 12K or 24K, and standard (230 GPa) versus higher-modulus grades, with tensile strength and linear density from the Zbrehon catalogue.
How to choose alkali-resistant fiberglass mesh for EIFS and exterior plaster: glass type, zirconia content, weight, hole size, tensile strength and alkali-resistance retention.
Carbon fiber prepreg or dry woven fabric? Zbrehon catalogue weights (100–480 g/m² fabric, 200–400 g/m² prepreg at 42% resin), weaves and cured-ply thickness.
Standard carbon fiber tube sizes from the Zbrehon catalogue (6–20 mm OD, 500 and 1000 mm lengths, square profiles from 1.4 mm) and how to choose roll-wrapped or pultruded.
Standard pultruded carbon fiber rod diameters (0.5–5.0 mm) and strip sizes (0.2 × 2 to 6 × 30 mm), all 1000 mm long, from the Zbrehon catalogue.
