SMOOTHING THE LANDING IN ADVANCED
COMPOSITES
Tullo A
The anticipated downturn in commercial aircraft is
causing advanced composite makers to look to nonaerospace
applications, such as sporting goods, satellite
materials, electronics and telecommunications, to help
level the cyclicality of aerospace applications. Cytec
became the largest US producer of both composite
prepregs and aerospace adhesives last year with its
purchase of Fiberite’s prepreg business. The US prepreg
tape market is estimated at 1.4bn US dollars and is
growing at between 7 and 9%.

APPLICATION OF LAMINATES TO
MOUTHGUARDS: FINITE ELEMENT
ANALYSIS
Ho Sung Kim; Mathieu K
Newcastle,University
A finite element model comprising a flat-ended indentor
and disc representing a colliding object and mouthguard
materials, respectively, was developed to study stress
distribution and impact force in laminates. The disc
consisted of two layers and its top layer was in contact
with the indentor. The effects of modulus and volume
fraction on stress distribution and force transmitted in
laminates were studied using the finite element model
for a collision in contact sports such as boxing or football.
The material used for the test was ethylene-vinyl acetate
copolymer. 12 refs.

SOFT TPE’S ARE OPTIMIZED FOR
EXPANDING ROLES IN CONSUMER GOODS
Grande J A
This article examines the trend by manufacturers to use
innovative soft (i.e. low-durometer) thermoplastic
elastomers (TPE’s) to provide improved tactile
characteristics, along with better ergonomics and
aesthetics, for consumer-friendly goods sporting easy-tohandle
grips, handles, and covers. The marketable
advantages of soft-touch TPE’s is fully investigated.

MDI-BASED URETHANE PREPOLYMERS AS
BINDERS
Moore D
Industrial Copolymers Ltd.
The use of granulated rubber crumb bound with one- or
two-component PU binders has become increasingly
popular in sports and safety surfacing. The rubber crumb
granules are normally ground from scrap commercial
rubber tyres, as car tyres often contain high levels of
additives that make them unsuitable for this purpose. This
process benefits the environment because it eliminates
problems associated with the disposal of tyres. In the
USA, many states have banned the dumping of tyres in
landfill sites. Furthermore, it is estimated that by re-using
rubber granules with a polymer binder, energy savings of
107,000 to 111,500 kJ/kg are achieved compared with
the incineration of scrap tyres. Sports and safety surfaces
usually contain more than 80% recycled product. Details

NEW IN-LINE SKATE CLIPS ON OR OFF IN

Du Pont Italiana SpA
Until recently, MGM developed and made sports shoes sold
mostly under various well-known brand names. The
company then entered the in-line skate market in 1996 with
the launch of the Hypno. This patented design’s big selling
point is that the wheels can be easily removed from the shoes
and fixed on again in a moment. In MGM’s original design
the chassis was made in two sections, one of aluminium,
one of plastic. That made for a lengthy manufacturing
process, with a complicated assembly procedure and the need
