“Fiber-reinforced plastics pose a particular
challenge… these complex processes can only
be mastered with know-how and the right
software technology.”

What is Multi-Ply?
Unique Composite Design Methodology
• Easy to understand and implement
• Powerful automation of design definition
and change
• Automated ply geometry creation
3 Reinforcement Plies
3 Reinforcement Plies
4 Full Plies
• Zones are independent
• Material is additive
• Layers can be shuffled

Multi-Ply Versus Other Methods
Ply Based Design
+ Flexible
• Define any shape
• Minimal Overhead
• Just geometry and plies
– Manual
• All ply geometry must be
created
• Limited automation
downstream (no IML)
Zone Based Design
– Highly Structured
• Interconnected zones create
initial overhead
+ Powerful
• Ply geometry is rule-driven
• Adapts well to changes
+ Automated
• Minimal geometry creation
• Downstream features easily
created (IML, DFM features,
etc)
Multi-Ply Design
+ Flexible
• Define any shape
• Low Overhead
• Input shapes directly drive
Ply shapes
+ Powerful
• Ply geometry is rule-driven
• Adapts very well to changes
+ Automated
• Minimal geometry creation
• Downstream features easily
created (IML, DFM features)
+ Can be combined with
Zone-Based Design

Multi-Ply Supports Any Category of Fundamental Part Complexity
Structural• Many plies of differing shapes and materials
• Mating condition / design rule constraints
Shape• Highly curved control surfaces
Process• Manufacturing automation with inherent limitations
• Large or small parts with material handling challenges

Ply-based Workflow
Initial Layup
1. Create Full-body plies
2. Create Pad-ups
1. Generate geometry manually
2. Create plies linked to geometry
3. Generate solid manually
Design Change – new pad-up
1. Create drop-off geometry
2. Create additional plies
3. Re-generate solid manually
+ Flexible
– Manual

Initial Layup
1. Create full-body area
2. Create pad-up areas
a. Fibersim stacks Lam Specs for you
3. Define drop-off rules
4. Generate layers automatically
5. Generate solid (IML) automatically
Design Change – new pad-up
1. Add new pad-up area
2. Generate layers automatically
3. Regenerate solid (IML) automatically

Zone-based Workflow
Initial Layup
1. Create Zones
2. Define material and drop-off specifications
a. Assign to zones

2. Create tear strap Zones one with 0 thickness (tricky!)
3. Define material and drop-offs specifications
a. Assign to tear strap zones
4. Generate layers automatically
5. Modify individual drop-offs, corners and stacking
1. Automatically modifies Layers
6. Regenerate solid (IML) automatically
