ABSTRACT = {The Piptadeniastrum Africanum bark tannin extract was characterized
using MALDI TOF, ATR-FT MIR. It was used in the development of a resin with
Vachellia nilotica extract as a biohardener. This tannin is consisting of Catechin,
Quercetin, Chalcone, Gallocatechin, Epigallocatechin gallate, Epicatechin gallate.
The gel time of the resin at natural pH (pH = 5.4) is 660 s and its MOE obtained
by thermomechanical analysis is 3909 MPa. The tenacity of Urena lobata fibers
were tested, woven into unidirectional mats (UD), and used as reinforcement in
the development of biocomposite. The fibers tenacity at 20, 30 and 50 mm lengths
are respectively 65.41, 41.04 and 33.86 cN·Tex−1
. The UD biocomposite obtained
had very interesting mechanical properties. Its density, tensile MOE, ultimate
strength, bending MOE and MOR are respectively 926 kg·m−3
, 6 GPa,
55 MPa, 9.3 GPa and 68.3 MPa. This biocomposite can be used in a building
exterior structure.},
