Buying Guide

Choose the right weave and finish

3K twill is common for a balance of appearance and strength; matte or twill finishes change reflectivity and scratch visibility

Match thickness to your application

Sheets range here from about 0.5mm to 5mm—thinner sheets work for overlays and weight-sensitive RC parts, thicker sheets add stiffness for structural uses

Confirm real fiber vs composite veneers

Look for listings that specify 'real fiber' or 3K fiber to ensure you're getting genuine carbon fiber fabric rather than a printed or coated veneer

Pick a size that minimizes waste

Common sizes like 200x300mm and 300x400mm suit small projects; choose a larger sheet if you need multiple parts to reduce seams and joints

Consider edge prep and machining needs

Carbon fiber can fray when cut—plan for proper cutting methods, edge sealing, or CNC finishing depending on your fabrication equipment
