“…(Davies et al 2006) applied Leech's model and found a good correlation of tension/torsion properties for results on full size long rope samples. Braided ropes have received less attention than stranded ropes, but some researchers have investigated behavior models, in particular (Rawal et al, 2015;Vu et al, 2015). The development of finite element simulations and other analytical models are helpful to understand the complex behavior of fiber ropes and the mechanisms of the bedding-in process.…”

Synthetic fiber ropes are widely used in the maritime industry, with applications from sailboat rigging to offshore platform mooring lines, thanks to their numerous qualities compared to steel cables: light weight, good specific mechanical properties and excellent marine resistance. A key feature of these ropes is their sensitivity to loading history, as this affects subsequent performance. In the present work the influence of the maximum bedding-in load level and the loading path were studied at the different rope component scales (filament, yarn and braided rope), in order to develop an optimal bedding-in procedure for braided ropes. The load levels were: 10%, 30% and 50% of the tensile break load of the sample. From the results obtained, the influence of braid construction and material have been studied, and an efficient bedding-in process has been defined. It was shown that the main parameter is the maximum load level, the loading path is not important. The load required to bed in HMPE ropes is closely related to changes in the braid angle under load. Highlights► Unique results of the influence of bedding in protocol on at different rope scales. ► Influence of bedding-in loading path and loading level on tensile behavior. ► Correlation between fibers reorientation and bedding-in protocols. ► Separation of contributions from material and construction.

“…An average of fifty readings was recorded for determining braid parameters. Furthermore, the stress-strain behaviour of constituent polypropylene filaments was determined, which was also discussed earlier in our previous research work (Rawal et al, 2015). The tensile testing of triaxial braided structures was recorded using 5 kN load cell and the other loading conditions were kept same, as employed for determination of tensile properties of constituent polypropylene monofilament strands.…”

“…The relations required to determine the volume fraction of the constituents of TBC and global stiffness matrix [C global ij of the dry fiber braid tows were taken from Byun. 13 The model applied for prediction of the tensile response of polypropylene braided sutures of 1.5 mm average diameter by Rawal et al 33 has been extended for the glass epoxy dry braided sleeve. The overall mechanical properties of the braids were obtained by considering only three constituent layers of the RUC neglecting matrix and by multiplying the volume fraction of the constituent in each layer.…”

The aim of this research work is to study the mechanical behaviour of dry triaxially braided glass fibre sleeves and its composites experimentally and analytically. The braided glass fibre sleeves for three angles 30°, 45° and 60° were fabricated on a modified maypole vertical braider following a regular braid architecture. Tensile, flexural, short beam shear and impact tests were performed to evaluate the mechanical properties of the composites. A numerical model was developed, which can be used to find the elastic properties and mechanical strength values of the dry braided fabric and its composites. It was observed that the tensile, flexural and interlaminar properties of 30° specimens were more compared to 45° and 60°. The difference between the estimated and experimental values were found to be an average of 8% for tensile moduli and 24% for the tensile strength.
