Composite Surfacing and Lightning Strike Protection

Wed, Aug 13, 2014 2:00 PM - 3:00 PM US Eastern Time

Surfacing films are designed to improve the surface quality of honeycomb stiffened composite parts. They also provide a barrier for dissimilar materials, decrease surface preparation time and provide protection of structural fibers. But this is not all: Laminated films composed of a surfacing film and a conductive metal foil protect the composite structure from damage caused by lightning strikes. PARTICIPANTS WILL LEARN: • Surfacing films for aircrafts • High thermal fatigue resistance • Lightning strike protection • Process labor reduction • Out of Autoclave solutions

Benzoxazine Composites Transform the Prepreg Value Chain

Benzoxazine matrix prepregs demonstrate many benefits throughout the value chain in performance, processing and supply chain. Performance improvements include high service temperature, improved flammability resistance and low moisture uptake. Prepregs have been optimized for use in automated processes, including automated tape placement and automated fiber placement, and for out of autoclave fabrication. Additional processing advantages include low cure exotherm and reduced shrinkage. The benzoxazine chemistry is stable at ambient conditions creating the opportunity for shipping and storage at room temperature. These multiple attributes create benefits throughout the value chain. PRIMARY TOPICS • Benzoxazine (BZ) resin prepreg materials • BZ structural performance improvements • Processing and fabrication of BZ prepregs • Supply chain cost reduction • Multiple benefits of BZ prepregs throughout the supply chain

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

Simulating ultimate failure: Converging on a solution with composite materials

In this Webinar, Doug Kenik will discuss the need for simulating past first ply failure in conventional implicit FEA tools and how to achieve convergence using Autodesk Simulation Composite Analysis. Simulating ultimate failure in composite structures using traditional implicit FEA codes can be very challenging. The behaviors of composite materials are inherently nonlinear during failure cascades, and FEA solvers can have difficulty converging on solutions during such events. Join us as we discuss simulating ultimate failure, and coupling inter and intra-laminar failure using Autodesk Simulation Composite Analysis coupled with Abaqus, ANSYS, and MSC Nastran to achieve convergence. Participants will learn: • Understanding composite behavior during failure • How to leverage Abaqus, ANSYS, and MSC Nastran with Autodesk Simulation Composite Analysis

High-Temperature, High-Density Epoxy-Urethane Foam: an Economical Alternative for Soft Tool and Molds

High-temperature, High-Density Epoxy-Urethane Foam is an economical and time-saving solution for soft small and monolithic or large-mass tools, low-rate and rapid prototyping because it can be more rapidly machined, easily bonded and it is more economical than wood, alloy or epoxy-based alternatives. Common applications: prototype machining, prepreg composite layup tooling, vacuum form tooling, tool proofing, pattern making and master model making. Primary Topics • Understanding Soft Tool Properties • Density Selection • Tool Preparation • Curing the tool Register for free today at https://www1.gotomeeting.com/register/690569177

Simulating FAILURE in Composite Materials

Imagine being able to replicate real-word failures of composite materials…on your computer. This webinar will cover WHY you would want to simulate the failure of a part or structure made from composite materials and HOW you can do that using Autodesk Simulation software. No longer is structural simulation limited to just looking at stresses, strains, and deflections. You can simulate the actual FAILURE of a composite part, and this can be done with minimal changes to your current simulation process. Primary topics (what the registrant will learn): • Introduction to Autodesk Simulation • Why Simulate Failure in Composites? • What Makes Autodesk Composites Simulation Unique?

Beyond Black Aluminum - Design, Analysis, and Optimization of Composite Structures.

Composites offer many advantages including the ability to tailor the material properties for the intended structural application. With this design flexibility also comes design complexity as we add a number of additional design variables to the design task. Computer based simulation and numerical optimization methods can greatly help the design engineer efficiently sort through the additional design variables encountered and converge to a good design. The technology is inspired by nature where the right material with the right stiffness is at the right place. Computer based methods can help us better understand where we do or - more importantly - do not need material and stiffness. This helps us achieve lightweight designs with composites that meet all of the design requirements. Primary topics (what the registrant will learn): Concept design synthesis for composites Modeling and analysis of laminated structures Design lightweight structures while meeting performance requirements
