Vehicle Lightweighting: Mixed Material Strategies Provide Automakers with a Lighter Future

To meet stricter regulations aimed at significantly reducing emissions and improving fuel efficiency, automotive companies must drastically rethink the way vehicles are engineered and manufactured. In this webinar, Edward Bernardon will discuss the evolution of CAD based engineering in order to achieve light weight body structures that meet cost, weight and performance targets. Join us as we discuss what the key issues are that need to be addressed by engineering software to efficiently engineer composite components and hybrid joints and assemblies, and how you can use Siemens PLM Fibersim and Syncrofit solution to support a mixed materials strategy. Primary topics (what the registrant will learn): • Understanding the impact of vehicle lightweighting • Industry trends related to engineering and design of hybrid material assemblies • How composites and assembly engineering software must evolve to support system tradeoffs • Introduction to Siemens PLM Fibersim and Syncrofit software

Realizing the Benefits of Syntactic Materials in Composite Structures

Low density syntactic materials give many opportunities to optimize weight, performance and manufacturing of composite structures. Syntactic materials are most commonly used in sandwich applications and can be expanding or non-expanding. Expanding materials are used mainly in applications such as honeycomb core splice, edge close-out and to provide reinforcement around attachment points. Additional applications include abradable seals for aircraft engines. Non-expanding syntactic materials provide high shear and crush strength compared to other traditional sandwich alternatives. Syntactic materials also provide manufacturing and processing flexibility. The webinar will discuss applications and benefits that can be achieved using syntactic materials. Primary topics (what the registrant will learn): Where do syntactic materials bring value? Different types of syntactic materials: expanding, non-expanding, structural Practical applications and benefits

Design for Producability and the Internet of Things (IoT) Push the Envelope of Production Efficiencies

Caught between increased production rates and growing cost pressures from the OEMs, manufacturers must improve part design and re-introduce the language of lean manufacturing in order to compete. In this webinar, Dr. Leslie Cohen (HITCO), and Avner Ben-Bassat (Plataine) will review case studies demonstrating the impact of part design on production costs, and will introduce the opportunity of the Internet of Things (IoT) in manufacturing, leveraging state-ofthe- art RFID and mobility technologies to better track and manage materials, kits, tooling, assemblies and staff on the production floor. Best-in-class engineering and manufacturing practices and technologies allow OEMs and fabricators alike to push the productivity envelope and reduce buy-to-fly ratios. PRIMARY TOPICS: 1. Managing the ingredients of a successful design process: customer requirements, engineering and manufacturing flexibilities and constraints 2. What is the Internet of Things (IoT) and how can it help to increase throughput, quality and quality control on the production floor 3. Establishing feedback cycles

Materials for Aircraft Interiors

Aircraft interior applications require a unique combination of properties and processing. Materials must have very low flammability, not only in terms of the ability to withstand flame impingement, but also the smoke and toxic gas released during exposure to fire. Materials must be processed easily due to the high volume of interior parts manufactured. Flammability requirements are becoming more stringent and composite materials are being used in more structural applications, both of which present increased demands on the materials being used. This presentation will introduce participants to composites and assembly solutions for aircraft interior applications. Primary topics (what the registrant will learn): Aircraft interior applications Performance requirements Material solutions for construction and assembly of interior components

Rolo Bikes uses Altair’s composites optimization to create the world’s lightest and stiffest road bike frame.

Rolo Bikes, has collaborated with Altair to develop the world's lightest and stiffest road bike. To optimize the carbon fiber frame, Altair ProductDesign utilized a three-step approach, during which the shape, thickness, direction and location of each layer of composite material was fine-tuned until an optimum solution had been reached. Each stage was performed using HyperWorks design optimization solution, OptiStruct®. The composite optimization process successfully reduced the weight of the frame from 829g to 792g. Additional material tweaks by Rolo’s manufacturing team reduced the weight even further resulting in a final weight of just 710g. Primary topics (what the registrant will learn): • Concept design synthesis for composites • Modeling and analysis of laminated structures • Size & shape optimization of composite sandwich structures

Composites Optimization and Analysis in Space Launch Vehicles: United Launch Alliance (ULA) Utilizes Free Size Optimization for a Doubler Repair of a Gouge Type Defect

Doublers are commonly used in launch vehicles to repair composite sandwich facesheet defects, such as gouges or depressions, because they locally increase the strength of the facesheet in the area of the repair. Although doublers can be of a different material than the facesheets, they often have comparable strength and stiffness. Therefore, the doubler’s influence on the overall extensional and bending stiffness of the sandwich can be significant. ULA explored the use of OptiStruct, HyperWorks’ structural optimization and analysis solver, to optimize the size and shape of a composite doubler to minimize the stresses. Participants will learn: • Concept design synthesis for composites • Modeling and analysis of laminated structures • Size & shape optimization of composite sandwich structures
