ABSTRACT: In this work we determine the physical and mechanical properties of local
composites reinforced with papaya trunk fibers (FTP) on one hand and particles
of the hulls of the kernels of the garlic (PCNFA) in the other hand. The
samples are produced according to BSI 2782 standards; by combining fibers and
untreated to polyester matrix following the contact molding method. We notice
that the long fibers of papaya trunks improve the tensile/compression
characteristics of composites by 45.44% compared to pure polyester; while the
short fibers improve the flexural strength of composites by 62.30% compared to
pure polyester. Furthermore, adding fibers decreases the density of the final
composite material and the rate of water absorption increases with the size of
the fibers. As regards composite materials with particle reinforcement from the
cores of the winged fruits, the particle size (fine ≤ 800 μm and large ≤ 1.6
mm) has no influence on the Young’s modulus and on the rate of water
absorption. On the other hand, fine particles improve the flexural strength of
composite materials by 53.08% compared to pure polyester; fine particles
increase the density by 19% compared to the density of pure polyester.
