An Introduction to the Joining of Composite Structures: Design, Analysis & Issues, Dr. Rikard Benton Heslehurst, University College, UNSW

Unlike metals structures, the requirements for geometric sizing of a composite mechanically fastened joint are often more critical, particularly when the joint is bearing primary loads. In adhesively bonded joints design the free ends of the joint are the critical condition where particular care must be taken to ensure peeling stresses are kept low. This 3 hour presentation gives participants an introduction into the understanding of the unique requirements for mechanically fastening of composite structures, and what needs to be considered when design adhesively bonded joints for full load transfer and longevity.

The question often asked as to whether to use mechanical fasteners or to adhesively bond a structural joint. This question will be clearly answered in generic terms during the presentation. A good understanding of the design and analysis of composite structures is discussed to aid the application of joint technology and allow efficient preliminary design sizing of composite joints to be undertaken. Some design and analysis charts will be provided to highlight the presentations practical aspects of composite joint design.

Rik has worked in the composites industry for over 30 years. Initial as an aeronautical engineering officer in the RAAF and now as a Senior Lecturer at University College, UNSW. Rik is the Senior Engineer for Abaris Training - Reno NV, and a consultant engineer for several companies in Australia and the USA. He has conducted dozens of composite engineering short courses throughout the world. Rik has a PhD from the UNSW and is the chair of SAMPE Australian Chapter.

· Metal tooling(materials and tolerances)

· Composite tooling construction

· Prototype/Short Run Tool Selection and Fabrication options

· Tooling Masters/ Advanced foam materials

· RTM and Light RTM tooling

· New Innovations and developments in Tooling for Composites

Engineers have to weight many considerations when designing and fabricating a tool for Composite Fabrication, many of these considerations will be addressed: CTE, Spring In, Surface Finish, Temperature Use, Number of Cycles, Cost, Lead Time, and Tolerance. The attendee should come away from the tutorial with a fundamental understanding of tooling issues, options, and methodology for selecting the best solution for their applications.

Nanocomposites Technology: Fundamentals, Properties, and Applications, Dr. Joseph H. Koo, The University of Texas at Austin

An introduction overview will define nanotechnology and its uniqueness/capabilities as an “enabling” technology allowing the introduction of small amounts of nanomaterials in polymer systems resulting in the formation of a “polymer nanocomposite (PNC)” exhibiting multi-functionalities. The discovery of new nanoscaled materials such as nanoclays, nanographenes, carbon nanofibers, carbon nanotubes, polyhedral oligomeric silsesquioxanes (POSS®), nanosilicas, nano-alumina, and others offer promise of a variety of new composite, adhesive, coating, and sealant materials. These PNCs possess unique properties unavailable with conventional materials. The creation of the U.S. government sponsored “National Nanotechnology Initiative” has been the platform for promoting many research programs within academic, industry, and government laboratories. Some of the topics to be discussed in this tutorial are:

· Overview of nanomaterials commonly used in polymer matrices

· Polymer matrices consisting of thermoset, thermoplastic, and thermoplastic elastomer resins

· Use of XRD, TEM, SEM, and AFM analyses to assess dispersibility

· Characteristics that polymer nanocomposites (PNC) exhibit enhancements in:

o Mechanical properties such as tensile/flexural strength and modulus

o Thermal properties such as thermal stability, T_g, flammability, HDT

o Electrical and thermal conductivities

o Ablation and insulative properties

o Tribological properties

· Transformation of polymer matrices into PNC: ablatives, coatings, fiber-reinforced composites, C/C composites, fire resistance materials

· Technology: Current status, trends, new developments, economics, and commercial applications

Introduction to Test Methods for Composites, Donald F. Adams, Wyoming Test Fixtures, Inc.

This tutorial is both an introduction for the novice and a refresher for the experienced individual involved in the design, testing, and manufacturing of composite components. Composite materials, whether for use in high performance structures or in commodity applications, present many unique testing problems. Thus, this tutorial is directed toward the proper selection of a test method for each specific application, from the many methods currently available. Examples will include properties characterization for mechanical design, and evaluations of manufacturing quality control. Although some test methods have been standardized by ASTM, ISO and other standards groups, many have not, having evolved as company standards in recent years. Therefore, it is important to be able to decide which test to use in a particular situation, and which composite characteristics are to be determined. The goal is to understand what needs to be done, and the time required, facilities, and costs involved in doing so. As this tutorial will demonstrate, mechanical testing can be very time consuming and expensive. Thus, it is especially important to do it correctly the first time. This is a particular challenge because of the wide range of test methods often available and in common use for determining the same composite property. Tensile, compressive, flexure, shear and fracture toughness test methods for unidirectional, laminate, random-fiber-reinforced, and sandwich panel composites will be reviewed. This will include the special problems involved when making evaluations at temperatures above and below ambient, and when testing moisture-conditioned specimens. In all cases, proper specimen preparation techniques and test procedures will be emphasized.

Adams is the founder and President of Wyoming Test Fixtures, Inc., a company specializing in the design and fabrication of mechanical test fixtures for the composite materials community since 1988. He is also Emeritus Professor of Mechanical Engineering at the University of Wyoming where he was Director of the Composite Materials Research Group for 27 years.
