Abstract
It is known that the initial fiber waviness affects the stiffness and strength of the polymer composite material. The influence of degree of waviness on stiffness characteristics under uniaxial tension and compression of a polymer composite material was investigated by using numerical modeling. A computational approach based on a special periodicity cell with different fiber waviness was developed. The hypothesis regarding the impact of manufacturing stresses, appearing during a curing process on waviness growth, was tested. The results obtained explain the mechanism that causes difference in the stiffness observed in fiber composites in the longitudinal direction under uniaxial tension and compression.
