Performance is directional
Strength and stiffness are highest along the fiber direction; weave and ply orientation determine how the laminate carries load.
Appearance is not structural validation
Twill provides a cosmetic pattern, but structural design still depends on load, ply count, core and service conditions.
Control resin and voids
Wet-out, debulk, vacuum and cure strongly affect resin content, porosity and surface quality.
