摘      要：The Piptadeniastrum Africanum bark tannin extract was characterized using MALDI TOF,ATR-FT *** was used in the development of a resin with Vachellia nilotica extract as a *** tannin is consisting of Catechin,Quercetin,Chalcone,Gallocatechin,Epigallocatechin gallate,Epicatechin *** gel time of the resin at natural pH(pH=5.4)is 660 s and its MOE obtained by thermomechanical analysis is 3909 *** tenacity of Urena lobata fibers were tested,woven into unidirectional mats(UD),and used as reinforcement in the development of *** 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 *** 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 *** biocomposite can be used in a building exterior structure.
