Thermoset Resin Matrices –
Electronically emailed handout only
This tutorial will
cover the various methods and technologies of designing and building tools for
the fabrication of composite parts. In
addition to a description of tooling options, some guidelines for making
selections will be covered. The
following tooling topics will be covered in the tutorial:
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.
Composites Damage Tolerance: Materials & Structures
Instructor: Dr. Keshavanarayana Raju,
Surface cracks, cuts, delaminations and
low energy impact damage to composites – often are the Achilles Heel of composite
structures. Knowing the types of typical damage imposed and the resultant
effects would help to understand how best to design and analyze for such
problems. This tutorial examines and presents an excellent overview of damage
to laminated and sandwich composite structures. At the same time practical
observations of damage scenarios and methods for analytically assessing the end
result will be provided to the attendee. Some
of the topics covered are:
·
What
to expect in damage to laminated or sandwich composite structures
·
The
differences between notches, delaminations and low-velocity impact damage
·
Experimental
observations of typical damage
·
Prediction
methods for handling and understanding damage types
·
Damage
tolerance – what levels might be expected in composite structures
·
Scaling
approaches and effects – how they relate to strengths, failure mechanisms, and
observations in the real world
·
What
analysis methods are available and how accurate are they
Dr. Linda Clements, C&C Innovation Strategies
Inc.
This tutorial provides a basic understanding of
composites, of their component fibers and resins, and of their advantages and
limitations. It will give participants an overview of properties, performance
and typical applications. Upon completion of this tutorial the participants
will have the basic understanding of composites that will allow them both to
profit from attending the SAMPE symposium and exhibition and to apply their
understanding to their jobs. The tutorial is appropriate not only for those
having little or no experience with high-performance composites, but also for
anyone desiring a more complete understanding of composites. Past attendees
have included designers, M&P engineers, shop personnel, technicians,
students, managers, and sales and business development specialists. Some of the
topics covered in this educational tutorial are:
·
Basic definitions and
types of composites
·
Overview of when
composites should – and should not – be used
·
Means for achieving
outstanding performance with composites
·
Overview of fiber
reinforcements for routine composite applications
·
Overview of fiber
reinforcements for exotic applications
·
Overview of resin
matrix materials for common environments
·
Overview of resin
matrix materials for extreme environments
·
Overview of resin
matrix materials used in composites
·
Composite limitations
and methods for overcoming them
Design & Analysis of Composite Materials &
Structures
Dr. Dan Adams,
Whether established
in composite materials testing or new to this field, this tutorial will provide
the attendee with insights into current practices and recommended procedures
for mechanical testing of composites. While providing background information on
mechanical properties to be measured and traditional test methodologies, this
tutorial will highlight recent advances and current practices. Additionally,
the different test methods available for composite material characterization
will be discussed, and guidance provided on selecting the best suited test
method and procedure for a particular application. Some of the topics covered
are:
· Review of mechanical properties of
composite materials
· Unique aspects of testing composites
(as opposed to metals)
· The need for standardized test
methods and the role of customized test procedures
· Recommended test methods/procedures
for tensile, compressive, shear, flexural, and other critical design properties
· Testing of textile composites and
sandwich composites – which are equally important
· Recent developments/advances in
composite materials testing
· Sources of information and
additional guidance for testing composites
Dr. James
Senger, Cytec Engineered Materials
The
utilization of fiber reinforced thermosetting resins for composites is an area
of significant commercial interest. The scope of the tutorial is however limited
to thermoset matrices used in advanced composites (i.e., continuous fiber
reinforcement) for demanding applications; predominately for aerospace and high
performance automotive. Resin chemistries discussed include:
·
Benzoxazines,
·
Bismaleimides,
·
Cyanate
esters,
·
Epoxies,
·
Phenolics,
·
Polyimides,
and,
·
Energy-curable
resins are also described
Structure
property relationships, cure mechanisms, characterization methods and typical
applications are provided for each resin family.
Testing of Composite Materials
Dr. Don Adams,
Intended as both an
introduction for a novice as well as a strong refresher for the experienced
individual, this tutorial covers the essentials associated with designing a
test, fabricating representative material samples and conducting the test
appropriately. Test methods are important to established industries such as
aerospace – but more recently are becoming more important for qualifying
materials and structures within the wind energy, oil and gas, solar energy,
alternate fuels, repair and maintenance, compressed natural gas (CNG, NGV), and
hydrogen fuel areas. Consequently, this tutorial will be directed toward the
proper selection of test methods for specific applications, from many methods
currently available. This tutorial will focus on:
·
Specimen
selection and preparation procedures,
·
Industry
standards within various market segments,
·
Tensile,
compressive, flexure, shear and fracture toughness tests,
·
Testing
of unidirectional, laminated materials, sandwich structures, random fiber
reinforced materials and fabric composite materials,
·
Special
problems associated with bonded interfaces and environmental aspects (high, low
temperatures), and,
·
Numerous
examples across several industries
Composites Repair Technology & Issues
Louis Dorworth, Abaris Training
Resources Inc.
This tutorial will
be of interest to those involved in repairs to composite structures. Basic requirements
for performing reliable structural repairs to composite components and large
scale structures will be addressed. This presentation applies to many different
industries ranging from aerospace to wind energy to motorsport racing. In this tutorial the pros and cons of using
different materials and methodologies so that engineers can choose the
appropriate repair design that best suits the type of structures that they are
repairing will be presented and discussed. Applicable tools and equipment are identified
with some emphasis on the new equipment specifically designed for wind energy
blades and other large scale surface repairs requiring moderate temperature
cure cycles. Questions are encouraged during the presentation as it is designed
to be an interactive discussion format. Topics included in the presentations
will include:
·
Defining
whether the repair is possible for the damaged structure,
·
Establishing
the appropriate materials and process for the repair,
·
Preparation
of the repair region,
·
Repairing
the damaged region back to structural sufficiency,
·
Assessing,
inspecting and assuring repair conformance and integrity, and,
·
Analyses
associated with typical repairs (if any)
