In recent years, there has been an intense search
worldwide for an alternative
material, which can substitute the asbestos fibre, a
component of the asbestos cement,
which has been found to be hazardous to human and animal
health and has been
banned already in many countries. Since 1979 the Non-
conventional Materials
Research Group of PUC-Rio has carried out works on the
application of vegetable
fibres, available in abundance in Brazil, for the
fabrication of construction
components, aiming mainly at the fabrication of popular
housing. The curaúa fibre
has been studied as it is already of popular use in the
manufacturing of ropes, baskets
and carpets in the region, known as Baixo Amazonas, in the
state of Para, where the
first plantations have been organized on a commercial
scale. In this work, the
physical, mechanical and micro-structural properties of
the curauá fibres, as well as
their application as a cimenticious matrix reinforcement,
have been studied. The
performance of curauá fibres and its composites was
compared with other vegetable
fibres, such as sisal, coconut and jute, as a substitute
for asbestos fibres and its
composites. The data on sisal and coconut fibres from
previous works by the same
research group at PUC-Rio was considered for comparison.
The behaviour of jute
fibres, as well as cimenticious composites, reinforced
with jute and sisal fibres, have
also been studied in this work. The results have shown
that the curauá fibre has good
physical and mechanical characteristics that make it
suitable to be used as
reinforcement of cimenticious matrices, with a high
ductility and post-cracking
resistance capacity.
