Fabrication and mechanical characterization of glass fibre reinforced triaxially braided composites

Abstract

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.

“…They observed that there is an optimum braiding angle of about 24° which guarantees the desired mechanical properties of their rods. The Damage of braided composites was investigated by various researchers and some of them provided methods to predict the damage progressive and failure of braided composites using numerical models 8–17 . Zhang et al 8 studied the failure and propagation damage of a braided composite under axial tensile loading.…”

“…They introduced temperature and humidity as the first and second factors determining environmental conditions, respectively. Marrivada et al 13 investigated the mechanical behavior of three‐axial braided composites made of glass fibers at three braiding angles of 30°, 45°, and 60°. They observed the damages by the microscopic images and stated that the tensile properties decrease as the braid angle increases.…”
