In this study, the thermal stability of sisal in cycle process was investigated between room temperatures and 600°C in various
conditions (in air, in composites, in argon) by thermogravimetry and mechanical testing measurement. The results indicated
that the thermal stability of sisal was worse in air before five times of thermal cycles, but after the five times thermal
stability of sisal in composites was better. In different conditions of same cycles process, the thermal stability of sisal
was different. With increasing of thermal cycles times, the max. load (is the maximum strength in stress-strain curve) of
sisal fiber showed downtendency in different conditions and decreased most obviously in composites.
Pyrolytic process has a promising potential for the environmentally friendly upgrading of lignocellulosic and plastic waste.
Thermogravimetry and pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) were used to get information about the reactive
decomposition of PCL in binary mixtures with microcrystalline cellulose (MC) or sisal fibres (SF). Preliminary thermogravimetric
investigation showed that biomass is thermally degraded at lower temperatures than PCL and this process has a predominant
influence on the thermal behaviour of the mixtures. Discrepancies between the experimental and predicted TG/DTG profiles were
considered as a measurement of the extent of interactions occurring on co-pyrolysis. It was found that reactivity of PCL was
slightly increased in PCL-SF binary mixtures. Evolution of acidic products from cellulose and hemicelluloses decomposition
may promote PCL degradation in binary mixtures with SF. It seems that the co-pyrolysis process could have potential for the
environmentally friendly transformation of biocomposites.

Other studies discuss nucleation influence of other lignocellulosic materials, primarily, natural fibres. For example, by using short sisalfibres, an increase in the crystallisation temperature and crystallinity
