TS EN 4408-002

TS EN 4408-002 is the second part of the aerospace drawing standard for parts made from composite materials, focused specifically on laminated parts. It sets out the rules for representing laminated components and for indicating the information that must appear on technical drawings, and it is intended to be used together with EN 4408-001.

Why laminated composite parts need their own drawing conventions

Laminated parts are built from multiple layers arranged in a controlled sequence. In aerospace structures, that layered make-up is central to the part’s performance, because the orientation, stacking sequence, thickness and build-up direction influence the final mechanical behaviour. For that reason, standardised drawing practice for composites has to communicate more than outer geometry alone; it must also carry the structural information needed to interpret the part correctly.

What this part addresses in technical documentation

• How laminated parts are represented on drawings
• Which information should be indicated in the technical drawing
• Drawing presentation for aerospace structures using laminated parts
• Complementary use with EN 4408-001

In general technical practice, composite drawing standards help designers, manufacturers and inspectors use the same visual language for a part’s geometry and its layered construction. That consistency supports clearer communication across development and production, especially where composite laminates are used in demanding aerospace applications. TS EN 4408-002 serves as a specialised drawing convention for laminated parts within that broader documentation framework.
