Performance of Unidirectional Biocomposite Developed with Piptadeniastrum Africanum Tannin Resin and Urena Lobata Fibers as Reinforcement

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