Studies and research activities conducted in the fi eld of high-technology materials
show that advanced composite materials are successfully used in key components for
many fi elds of applications, from aerospace & automobile industries, marine construction,
renewable energy, modern medicine to micro-/nano-material technologies, including
other more complex civil and mechanical engineering assemblies. In addition
to this variety of applications, the considerable increase in demand of these smart materials
will open up many opportunities to design and manufacture new products for
the future. However, these products have to satisfy sustainable development requirements,
which can be achieved by a balanced equation that simultaneously guarantees
economic growth and environmental protection.
According to these ecological considerations, researchers and industrials involved
with high-technology composite materials are strongly encouraged to integrate ecodesign
aspects into the composite product lifecycle, providing then a bett er assessment
of environmental and health performances. Furthermore, “going green” can also contribute
to the world’s socio-economic well-being and living conditions for present and
future generations.
By adopting these principles of sustainable design, I am pleased to have this opportunity
to edit this new book, which opens a new challenge in the world of composite
materials and explores the achieved advancements of specialists in their respective
areas of research and innovation.
The scientifi c and technological research contributions coming from both spaces of
academia and industry were so diversifi ed that the 28 chapters composing the book
have been grouped into the following main parts:
• Sustainable materials and ecodesign aspects: research was focused on the integration
of environmental aspects in the diff erent stages of the design process, development
of eco-friendly, non-asbestos and fully biodegradable macro-/micro-/nano-composite
materials exhibiting less pollution and waste.
• Composite materials and curing processes: investigations were undertaken on
some technologies of fabrication and on the simulation of the curing process with a
reduction of VOC emissions and energy consumption.
• Modelling and testing of composites: studies were conducted on mechanical characterization,
tolerance analysis, fl uid-structure interaction, buckling phenomenon,
delamination growth and stress analysis using in one hand numerical approaches,
such as fi nite element method and on the other hand experimental investigations.
• Stress-strength analysis of adhesive joints: experimental testing, design formulas
and FE codes were used to predict the failure strength of the joint and evaluate the
structural behaviour of the damaged elements that were repaired and reinforced with
adhesive layers.
• Characterization and thermal behaviour: properties of composite material devices
for high demanding applications were investigated experimentally and numerically.
The results achieved from theoretical, numerical and experimental investigations can
help designers, manufacturers and suppliers involved with high-tech composite materials
to boost competitiveness and innovation productivity. Specifi c recommendations
are to give much more focus and att ention to (i) the chemical substances used in
the manufacturing process, (ii) the amount of VOC emissions, (iii) the enhancement of
quality-health-environment performance, (iv) the amount of waste produced, expired
materials and ways of recycling, (v) the classifi cation of companies and fi rms with regard
to the new regulations and eco-standards, and more…
The editor would like to thank all Chapter Authors for their remarkable contributions
coming from all around the world and appreciate the resulting synergy between academia
and industry. Without this rich variety of contributions, the existence of the
Book “Advances in Composite Materials- Ecodesign and Analysis” would not have been
possible.
