Seminar cum workshop: Design and Development of Solutions for High Performance Composite with Integrated 3D Simulation Technology

Date: 15 Jun 2011 - 15 Jun 2011

Venue: SIMTech Auditorium, Tower Block, Leve 3

Introduction

From aircraft fairing to train noses, from boat hulls to wind blades, composites offer tremendous opportunities to meet today’s ever increasing cost-driven market requirements and environmental concerns. CAE has been a key enabling technology for materialising many of these complex engineering structures, ensuring that they make a smooth transition from design to manufacture. This seminar cum workshop is jointly organised by SIMTech & Dassault Systemes to provide a platform for local composites and precision engineering (PE) industries to receive technical updates on the design and development of high performance composites using integrated 3D CAE technology. A technical workshop in the afternoon has been arranged to offer participants a chance to gain some hands-on experience in the use of CAE to enhance their product design and business development. This event is sponsored by Dassault Systèmes.

Recent Advances in Polymer Composites Manufacturing Technologies and Future Application 
and Development Trends - Dr Zhao Jianhong

Polymer composites have been widely used in various industries due to their excellent mechanical properties and low density, and good corrosion resistant to many substances which attack other materials. In recent years, a lot of progress have been made in composite substrate materials and fibre reinforcement development, as well as in manufacturing technologies to meet industrial needs. In this presentation, recent advances in polymer composite materials and manufacturing technologies, future application and development trends will be introduced. 

Accelerating Innovation of Composites Design & Analysis - Mr Narayan Sreenivasan, Dassault Systèmes
Ultra light, strong, highly resistant and durable, composites are ideal for producing lightweight structures with tremendous performance capabilities. Yet, designing and mass-producing complex production-ready composites parts is highly complex and expensive. Traditional composites solutions cover the design, analysis, and manufacturing of composites parts in a sequential, time-consuming, non-collaborative process burdened by heavily manual operations. Already in use at the major aircraft and helicopter manufacturers and suppliers, Formula 1 teams, as well as yacht designers and builders, Dassault Systèmes’ complete set of process-oriented solutions to design, simulate, and manufacture composite structures on a single virtual platform helps companies to:
- Keep composites development and build cost under control
- Reduce fabrication cycle time and shorten ramp-up time throughout the process, from initial design to manufacturing preparation and shop floor processing
- Manage the vast amount of data, large number of specifications, and the hundreds of plies generated, from design to manufacturing
- Predict global behavior in order not to over-design the part, undermine the initial lightweight properties, and incur additional cost
- Perform tedious, complex ply design while ensuring manufacturability by taking manufacturing constraints into account and generating the necessary output
- Communicate efficiently, promote concurrent engineering, and manage numerous interactions between composites engineering and manufacturing teams or cross-functional disciplines to prevent misunderstandings, errors, and delays.

At the heart of the solution, Dassault Systemes solutions provide a dedicated environment for the design of composite structures, including:
- Full definition from conceptual to engineering detailed design and manufacturing preparation
- Dedicated functional contexts to integrate structural, assembly, and manufacturing requirements early in the design phase
- Collaboration between cross-functional teams through powerful synchronisation mechanisms
- Knowledge-based engineering

Design and Certification of Composite Panels for the Airbus A380: Process and Challenges - Dr Shaibatul Hamid Macci, Strand Aerospace Malaysia
Strand Aerospace Malaysia (SAM) has been involved with the certification of wing components for the A380 since 2006. The company has worked on both primary (Spars and Skins) and secondary structural components for this aircraft.
In 2006, SAM was contracted by Composite Technology Research Malaysia to provide analysis and signatory support for the Forward Leading Edge Lower Panels (FLELP) that were being manufactured there. Part of SAM’s task was to reduce the voluminous analysis that had been produced to support MSN007’s certification to a more concise standard for MSN011. This talk will highlight the process that SAM took to achieve this as well as highlight the challenges the company encountered that reflect the challenges associated with analysis of composite structures.

New Development of High Performance Composites in SIMTech - Dr Surya D Pandita, SIMTech
Polymer composites have gained increasing interests and have been used in various applications such as automotive, sports/leisure, chemical facilities, construction, aerospace and others. In SIMTech, the composite group has been focusing on the development of nanocomposites, liquid molding techniques and fabrication of green composites. Incorporation of nano particles into polymer increases the physical properties and mechanical properties of polymer. Light Resin Transfer Molding (LRTM) is a modification of conventional Resin Transfer Molding (RTM), where only vacuum pressure and mechanical locks are applied into the mold. Therefore, the fabricated mold from the LRTM process can be much simpler, larger and cheaper than that of conventional RTM. Natural fibers are emerging to become more popular materials to be added as reinforcement in composites. Advantages which natural fibers offer include low cost, lightweight and  are an environmentally superior alternative to commonly used glass fibers reinforcements.
