Continuous glass fibre/PP composite is a material
particularly attractive as it can be processed without
emission of volatile products and used in applications
in which high stiffness and strength are required. The
automotive industry plans a number of uses for this
class of material and other applications in marine,
transportation, sport and other industrial uses are also
expected. As a result of this huge potential volume of
production, a growing amount of waste material is
expected for the next few years. It is shown that the
continuous glass fibre fabric PP composites are
thermally stable in strong recycling conditions, making
them an attractive choice for applications in which high
stiffness, strength and recyclability are required. While
the use of conventional technologies for recycling of
continuous glass fibre fabric PP composites do not
permit to obtain composite material showing structural
performance this leads to performance equivalent to
those observed for the long glass fibre injection
moulding grade and 50% of the performance of the
compression moulded GMT preform. 6 refs.

(SPE,Thermoplastic Elastomers Special Interest Group;
SPE,Philadelphia Section)
Thermoplastic elastomers have been used extensively
in the consumer, electronics, power tools, horticultural,
appliances, telecommunications, personal care
products, and sports and leisure markets either as an
insert moulding or as an overmoulding substrate in
combination with rigid materials. The results are better
soft-touch feel, ergonomics and a change of consumer
taste preferences in soft versus hard feel. Several
classes of thermoplastic elastomers that are designed
as insert or overmoulding compound for high impact
PS, K-resin, PP, ABS and polyamides such as nylon 6
and 6/6 without the use of adhesives are discussed.
Mechanical properties of these materials are covered.
Some typical applications and materials selection are
illustrated.

OLYMPIANS TO PLAY ON POLYPROPYLENE
TURF
Weston P
Details are given on a new turf with polypropylene fibres
woven through its base to strengthen the playing surface.
The new sports surface is said to improve drainage and
make the ground softer and can also be rearranged,
allowing worn areas to be replaced.

EXEL ACQUIRES FIBERSPAR PERFORMANCE
PRODUCTS’ BUSINESS OPERATIONS
Details are given on the acquisition of Fiberspar
Performance Products by Exel Oyj. The companies
manufacture and market sports equipment such as
composite windsurfing masts and booms and it is said
that the acquisition will strengthen Exel’s technology
through Fiberspar’s expertise in 3-axial braiding and RTM
production method. It is hoped that these extra
technologies will enable Exel to offer products
manufactured with new fibre structure solutions and
improve their technological market situation.

LOOKING INTO THE SOLE - TESTING SHOE
MATERIALS
Dengler K; Lang A
adidas-Salomon AG
The design of sports shoes is described with reference to
the functions in terms of athletic performance of the sole
material and construction. The complex nature of the
variation of forces on the different parts of the shoe is
examined at the adidas-Salomon test centre by the use of
an Instron testing machine, which is capable of simulating
force-time relationships The test centre uses a 8502 testing
machine from Instron, which enables both the testing of
the damping properties of existing shoe soles and the
investigation and optimisation of further suitable
materials. Further details are given of the testing of sports
shoe designs and materials at the test centre.
