heRECYSITEproject aims todevelopbio-sourcedcomposite
materials based on vegetal fibers and resins based on
humins and epoxidized linseed oil (ELO). In turn these materials
will be used as parts in the transportation and constructions
sectors. Humins are a by-product of bio-refineries in the
production of furan-based monomers. As a by-product, they
can represent as much as 30% w/w in the industrial process.
From a chemical standpoint they are complex mixtures of furan
derivatives, in various degrees of polymerization. This aspect
offers perspectives towards higher value applications such as
polymers. ELO is an epoxidized vegetable oil containing 5.5
oxirane moieties per molecule. It is regarded as a bio-sourced,
renewable alternative to classical, synthetic epoxides. Resins
were produced from humins, ELO and Capcure 3-800 and
characterized through ATR (Attenuated total reflection)
FT-IR (Fourier transform infrared spectroscopy). Based on
formulation, a wide array of materials was obtained with shore
hardness varying from 56A to 66D. The thermal behavior of the
resins was evaluated through differential scanning calorimetry
and thermogravimetric analysis. Composites, employing as
reinforcement, five types of vegetal fibers were obtained. The
adherence of the resin to the reinforcement was evaluated
through scanning electron microscopy (SEM) and was found
to be optimal. Figure 1 displays the results of the project. The
obtained composites present a bio-based content up to 85%.
The mechanical properties of the materials can be adjusted
by adapting the formulation. The good compatibility between
the resin and the reinforcement proposes the materials as
candidates to replace classical materials in applications.
At this moment, the materials are tested as parts for the
transportation and constructions sectors.
