“…The effect of the specimen orientation on the macroscale mechanical properties has already been widely studied in literature. For instance, it has been shown that ultimate tensile strength [1] or elastic modulus [2,3] depends on fibre orientation. Mechanical properties anisotropy is strongly linked to different damage kinetics and mechanisms depending on the specimen orientation with respect to the applied mechanical loading [4].…”

Damage mechanisms of reinforced polyamide 6,6 have been studied in 3D through in situ X-ray tomography tensile tests. 3D pictures of the microstructure have been taken during tensile tests to catch damage evolution in the bulk of material. The effects of relative humidity and orientation sampling are particularly investigated in this paper. Main mechanisms have been identified such as fibre failure, debonding, damage at fibre ends and matrix damage (cavitation, fibrillation, damage growth). Qualitative observations reveal that the mechanisms are very sensitive to orientation sampling and relative humidity of the specimen. A specific procedure was developed to propose a quantitative analysis of the results. This analysis shows that identified mechanisms not only have different proportions but also have different kinetics according to relative humidity and orientation sampling of the specimen.

“…As a method of a short fiber orientation in a composite, an injection molding is an effective technique. 4), 15) The fibers in a composite prepared by an injection molding technique are aligned. 9),16) However, the content of the fiber is limited to 20 vol.% or less because the viscosity of the composite becomes high and the forming of composite is difficult at high short fiber loading.…”

In this paper, we investigated fiber orientations and flexural properties of composites, which were prepared from epoxy resin, curing agent and short carbon fiber (CF) below critical fiber length. The prepreg with CF, curing agent and epoxy resin was prepared by an extrusion method. We found that the fiber orientation was caused when the CF/epoxy composite exhibited a plastic behavior. The ratio of this fiber orientation was 0.71 within the angle from 0 to 10°. The flexural modulus and the flexural strength of this composite, which was prepared from fiber orientation prepreg, was 16 GPa and 211 MPa, respectively. The flexural properties were ca. twice large as compared to a composite with random direction of fibers, indicating that the flexural properties were significantly affected by the orientation of fibers even if the fiber was below critical length. Moreover, it was discussed that the effective coefficient of the short fiber orientation distribution was one of important factors to predict the flexural modulus of a composite.
