Interactive Presentation
Structural Batteries Made from Fibre Reinforced Composites
S Ekstedt, M Wysocki, L Asp (Swerea SICOMP AB)
Structural, fibre reinforced, battery prototypes with two types of electrolyte matrix material, a
gel and a solid polymer, have been manufactured. This was to confirm the concept of using
carbon fibre as current collector in the anode as well as load-carrying functionality. As a result,
functioning batteries with gel electrolyte have been produced and their properties are
currently being characterised. (IB5:1)
The Mechanical Properties and Absorbing Properties of Triangle Section
Carbon Fibers-Reinforced Polymer Composites
X Liu, W Rongguo, L Wenbo, Z Jianguang, Z Weiwei (HIT)
Triangle section carbon fibers (TCFs) produced by a new technology could be used as
structure radar absorbing materials (SRAMs). The mechanical properties, the complex
permittivity and absorbing properties of the TCFs-reinforced polymer composites (TCFRPCs)
were investigated. The composites have the load bearing and absorbing properties
simultaneously. (IB5:2)
Self-Actuating Fibre Reinforced Epoxy Composites
J Etches, I Bond (Univ of Bristol)
The work reports on the development a novel electrode configuration for activating glass fibre
reinforced hydrogel electro-active polymers. Work undertaken demonstrates the effectiveness
of using this approach in terms of improving the resulting actuation potential. Investigations
are ongoing into the refinement and possible application of this self-actuating composite.

Structured Multifunctional Composites for Power Storage Devices
N Shirshova, E Greenhalgh, M Shaffer, JHG Steinke, P Curtis, A Bismarck (Imperial College
London)
The fabrication and performance of composite materials based on carbon fibres, polymer
electrolytes and mesoporous silica is presented. The electrochemical and mechanical
properties of the obtained composites were systematically studied. (IB5:4)
Development of Self Healing Composite Materials: Fabrication and
Micro-Structural Analyses

(nanoComposix)
Inspired by nature, the concept of an autonomous self-healing material, where the initiation of
repair is an intrinsic characteristic of the material itself, became of extreme interest for
composites applications in the few past years. A new class of polymers has been developed
with the ability to repair internal micro-failures. This was accomplished by synthesizing a resin
based on a thermally reversible Diels-Alder (DA) and retro-DA cycloaddition. (IB5:5)
Influence of Geometry on GMI Effect of Co-Based Magnetic Composite
Microwires
F Qin, H-X Peng, N Pankratov (Univ of Bristol)
Scanning electron microscope and optical microscope were employed to examine structures
of the Co-based glass-coated amorphous wires. The relationship between the GMI properties
and geometry factors of wires is established in the context of the internal stress condition.

Self-Sensing of Delamination in Quasi-Isotropic CFRP Laminate using
the Piezoresistivity
M Ueda (Nihon Univ), A Todoroki (Tokyo Institute of Technology)
Self-sensing technique for damage in CFRP laminate was proposed. CFRP cloth is often
stacked onto a CFRP laminate as a protective layer to prevent surface damage and it was
thus used as a strain sensor utilizing its piezoresistivity. Delamination was identified from the
electric potential change of the CFRP cloth due to surface strain variation. (IB5:7)
