This work aimed to obtain and characterize a composite material from agroenergetic and
polymeric residues. It was composed of babassu coco epicarp fibers and different
polymeric residues, using as a matrix the Urea-formaldehyde resin. The composite
produced was analyzed for its physical, mechanical and morphological properties. The
properties of moisture and density are according to the ABNT Standard 14810-2 (2014),
for bonded wood sheets, except the PP20% composite that did not meet the density
requirement. The swelling contents in thickness and water absorption obtained
statistically better results, in the concentrations of 40% and 60% of resin. The addition of
PP plastic residues in the structural matrix of the composite panels, promoted an increase
in the performance of the mechanical properties of these, in relation to the PET residue.
The mechanical properties MOE, MOR and the compressive strength of the composites
were not influenced by the increase in UF resin content. In general, the produced
composites obtained results compatible with the norms for the physical properties and in
agreement with works referenced in the literature. The mechanical properties did not meet
the norm and were inferior to the results obtained by other authors. Microscopic analysis
by the MEV test allowed to verify the porosity and cracks of the UF resin, the high void
content of the composite, the waxy surface of the fiber and consequently the low adhesion
between the fiber and the matrix. Despite this, the use of babassu epicarp fibers for
composite materials has a promising future and has been well studied. It is believed that
the improvement of fiber preparation techniques and the use of technologies can improve
the performance of the babassu epicarp fiber composite.
