1 Optimized Composite Design Methodologies that Enable Rapid Change Realize innovation.

2 Agenda Multi Ply Introduction Application Rapid Change

3 Acquired by Siemens PLM Software 2011 Leading composite design solution in Aerospace and Automotive (300+ global customers) Solutions Specialized domains Industry Focused Multi-CAD, open architecture Customers include: Boeing, Northrop Grumman, Lockheed Martin, SpaceX, Spirit Aerosystems, Ford, Audi, Magna

4 Specialized Engineering Software Portfolio FIBERSIM Composite structures development MASTERTRIM Seat and interior component development SYNCROFIT Complex assembly engineering

5 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

6 Fibersim Has Specialized Composite Design Methods Only Siemens offers this range of capabilities Flexible design method for hand layup Ply geometry is rule-driven Adapts well to changes Ply Based Zone Based Automates design for wings/fuselages Combines zone method with ply method, allowing quick design modifications Structure Based Multi-Ply Based

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

8 What is Multi-Ply? Schematic Initial Stack-up Redefine Sequence

9 What is Multi-Ply? Create parametric surface offsets (IML) with ramps from overlay reinforcements Ramps for Drop-offs

10 Multi-Ply Versus Other Methods Ply Based Design Zone Based Design Multi-Ply Design + Flexible Define any shape Minimal Overhead Just geometry and plies Manual All ply geometry must be created Limited automation downstream (no IML) 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) + 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

11 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

12 Examples of Part Complexity Large Airframe Structural complexity Shape complexity Process complexity Very High Low Very High Zone-based Design/ Multi-Ply Design Model Merge Automated Deposition Design Automotive Panel Structural complexity Shape complexity Process complexity Low Very High High Multi-Ply Design CAE Exchange Simple Part Structural complexity Shape complexity Low Low Multi-Ply Design Parametric Offset Surface Process complexity Low

13 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

14 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 2. Generate layers automatically 3. Regenerate solid (IML) automatically + Flexible + Powerful + Automated

15 Zone-based Workflow Initial Layup 1. Create Zones 2. Define material and drop-off specifications a. Assign to zones 3. Generate layers automatically 4. Modify individual drop-offs, corners and stacking a. Automatically modifies layers 5. Generate solid (IML) automatically 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 4. Generate layers automatically 5. Modify individual drop-offs, corners and stacking 1. Automatically modifies Layers 6. Regenerate solid (IML) automatically + Powerful + Automated Structured

16 Zone & Multi-Ply Hybrid Workflow Initial Layup 1. Create Zones 2. Define material and drop-off specifications a. Assign to zones 3. Generate layers automatically 4. Modify individual drop-offs, corners and stacking a. Automatically modifies layers 5. Generate solid (IML) automatically Design Change Add Tear Straps 1. Create tear strap Zones (easy!) 2. Define material and drop-offs specifications a. Assign to tear strap zones 3. Generate layers automatically 4. Regenerate solid (IML) automatically + Powerful + Automated = Structured

17 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
