“Fiber-reinforced plastics pose a particular

challenge… these complex processes can only

be mastered with know-how and the right

software technology.”

- Georg Käsmeier, CEO and founding member Roding Automobile GmbH



Fibersim Has Specialized Composite Design Methods

Only Siemens offers this range of capabilities

▪ Flexible design method for

hand layup

Ply Based Zone Based

Structure Based Multi-Ply Based

▪ Ply geometry is rule-driven

▪ Adapts well to changes

▪ Combines zone method with

ply method, allowing quick

design modifications

▪ Automates design for

wings/fuselages



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

What is Multi-Ply?

Ramps for Drop-offs

Create parametric surface

offsets (IML) with ramps from

overlay reinforcements



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



Multi-Ply Workflow

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


3. Regenerate solid (IML) automatically

+ Flexible

+ Powerful

+ Automated



Zone-based Workflow

Initial Layup

1. Create Zones

2. Define material and drop-off specifications

a. Assign to zones


4. Modify individual drop-offs, corners and stacking

a. Automatically modifies layers


Design Change – Add Tear Straps

1. Create tear strap Laminate (more steps!)

2. Create tear strap Zones one with 0 thickness (tricky!)

3. Define material and drop-offs specifications

a. Assign to tear strap zones



1. Automatically modifies Layers


+ Powerful

+ Automated

– Structured



Zone & Multi-Ply Hybrid Workflow

Initial Layup

1. Create Zones

2. Define material and drop-off specifications

a. Assign to zones



a. Automatically modifies layers


Design Change – Add Tear Straps

1. Create tear strap Zones (easy!)

2. Define material and drop-offs specifications

a. Assign to tear strap zones



+ Powerful

+ Automated

= Structured



Benefits Summary – Multi-ply

• Delivers an open platform supporting NX, CATIA and Creo

• Uses company and program specific rules to drive composite design

• Enables faster and more frequent design/analysis optimization iterations

• Needs minimal geometry to automatically create ply shapes

• Generates downstream features automatically (IML, DFM, etc.)

• Combines best features of zone and ply based methodologies

80% time savings compared to other design methods

• Increase design efficiency

• Minimize geometry creation

• Reduce time to make changes
