Design Principles

"Layering strategy in composite materials is a critical design parameter for performance under impact loading."

Yacht design frequently encounters the challenge of balancing lightweight construction with robust impact resistance, especially in areas prone to collision. Understanding how material layup affects performance under impact allows designers to create safer, more durable vessels without compromising on weight or speed.

What This Means for Your Design

Putting carbon fiber in the right place within a mixed material (like carbon and glass fiber) makes boats much better at surviving bumps and crashes.
