Abstract EN
The aim of this study is to experimentally determine how the weave architecture and yarn crimp affect the measured tensile stiffness and strength of composites containing 3D textile reinforcement.
It is shown that both the stiffness and strength decrease nonlinearly with increasing 3D crimp.
The ultimate strength of specimens containing nominally straight yarns and specimens containing crimped yarns can differ more than a factor of 3, and the stress causing onset of damage can be affected even more.
Adding nominally straight stuffer yarns into a 3D-woven reinforcement significantly increases the fibre volume fraction, the stiffness, and the strength of the composite.
However, since the stuffer yarns are virtually straight and thus stiffer than the warp yarns, they attract the load and reach their strength at relatively lower strain than the warp yarns.
The reinforcement architecture varies between the surfaces and the interior of the studied textiles, which has corresponding influence on the local stiffness.
The onset of failure is predicted satisfactorily accurate with relatively simple estimations.
The ultimate strength is a result of extensive damage progression and thus more dubious to predict.
