COMPOSITE STRUCTURE FOR A CLASSICAL
DANCE FLOOR
Landjerit B; Simon G; Barrey E
CER-ENSAM; INRA
Three types of composite structure, i.e. wooden beams
and plates with foam supports and sandwich structures
consisting of glass fibre-reinforced epoxy resin skins with
foam or honeycomb cores, were evaluated for use as
classical dance floors. The investigation involved
computer modelling and accelerometry studies, and the
vibration frequency and response to dynamic loading of
the different floors were analysed. The combination of
wooden beams and plates with elastic and vibration
damping supports gave floors with good stiffness and
damping characteristics. Sandwich structures with
honeycomb cores also gave good results, but at a higher
cost compared with wooden composites. Results for foam
core sandwich structures indicated that they were not as
suited to this application. 6 refs.

Plastic applications are reported to be continuing to grow,
but exhibitors at the Interbike international bicycle
exposition displayed fewer material innovations than a
few years ago. An outline of developments in this area is
presented.

OLYMPIC GROUP CLARIFIES STANCE ON
PVC
Tilley K
Australia’s Olympic Coordination Authority has refused
to rule out the use of PVC in facilities constructed for the
2000 Olympics, despite a restriction included in
environmental guidelines used to secure the Olympic bid.
Sydney’s environmental guidelines for the 2000 Olympics
include minimising, and ideally avoiding, the use of
chlorine-based products such as PVC. Australia’s plastics
industry was angered by the specific mention of PVC,
which it blamed on Greenpeace Australia’s long-running
campaign to ban PVC. Following requests from the
plastics industry, the Sydney-based Olympic Coordination
Authority clarified its position. In a statement, OCA said
all building materials for Olympics facilities will be
subject to impartial environmental scrutiny. All building
components will be uniformly subject to life-cycle costing
and consideration of environmental implications. Details
are given.

RUBBER DRESSING TOUGHENS FAIRWAYS
Sowa S
Denver-based scrap tyre processing and marketing
company, Jai Tire Industries, believes that it has found a
way to reduce the competition in the turf maintenance
industry. It holds the marketing rights to what is thought
to be a high-value use for crumb rubber. Jai Tire sells the
recycled scrap tyre material to golf course and athletic
field managers for use as a turf grass top-dressing. In hightraffic
areas, the application of crumb rubber above the
soil line protects the crown of the plant’s root system and
reduces underlying compaction and scarring of the blade
from the abrasiveness of sand. Details are given.
