“…These materials have better out-of-plane properties (for example stiffness, strength and toughness), lower manufacturing cost, easy to handle, high energy absorption and high damage tolerance compared to tape laminates [31,32]. Hence, the composites reinforced with braided fabrics are potentially used in marine, automobile and aerospace industries [31,33]. Rajesh and Pitchaimani [34] experimentally showed that the mechanical properties of the natural fiber woven fabric with flat braided yarn filled polyester composites are increased compared to conventional yarn woven fabric and short and random fiber filled polyester composites.…”

Recent advances in the development and application of bio-based (natural fiber and biopolymer) composites are gaining broad attention because the resulting polymer completely degrades and does not release harmful substances. In this study, natural fiber 3 D braided yarn textile PLA (Polylactic acid) bio-composites are developed by film sequencing followed by hot-press compression molding. Bio-deterioration and thermal stability of the composites are analysed for storage, machining, transportation, and in-service uses in different environmental conditions (compost and thermal). Composite samples with different fiber wt.% (0, 22, 44) are exposed to compost soil. Tensile testing is performed under different configurations to characterise the tensile properties. Prepared bio-composite specimens are evaluated for weight loss and reduction in tensile properties over soil burial time, to observe the rate of biodegradation of braided yarn textile bio-composites. Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) is employed to analyse the biodegradability of the composites. To study the thermal stability of the prepared bio-composites thermogravimetric (TG) analysis is carried out. Results showed that biodegradability, tensile properties and thermal stability of the composites are enhanced significantly with the reinforcement of 3 D braided yarn fabric.

“…'The four-directional 3D braided composites are more advantageous as a primary load-bearing component, compared to 2D laminates in terms of their mechanical properties, high impact energy absorption, impact damage tolerance, superior crashworthiness properties due to through-thickness reinforcement and potential to produce near net shape preforms inexpensively' [1][2][3]. Further, low-cost methods such as resin transfer moulding and vacuum-assisted resin infusion can be used for 3D braided composite fabrication.…”

“…Therefore, 3D braids can be safely called as solid braids. 3D braids are classified as horn gear type [3,6] and track and column type (two-step and four-step braiding) [8,9]. The track and column type is sometimes called as cartesian braiding.…”

“…The internal structure of 3D braided preforms has received much attention compared to its external shape. The yarn topology in the 3D braided preform decides yarn orientation and fibre volume fraction of the preform [3]. The yarn topology changes with braiding method adopted such as surface-core braiding [14], multilayer braiding [10], multilayer interlock braiding [15], and orthogonal braiding [16].…”

The present research reports the geometric model of four-directional 3D (4D3D) braided preform developed on four-step 3D braiding machine which consists of even and an equal number of yarn carriers in the rows and columns, respectively, on machine bed. The yarn path within the unit cell of the preform was analyzed to establish the correlation between surface braiding angle and interior braiding angle. A single unit cell model approach was used to predict the fibre volume fraction of the preform. It has been observed that the number of yarn carriers in the rows and columns is a critical parameter to decide the geometry of 4D3D braided preform. The fibre volume fraction predicted by the present model was compared with the three-unit cell model, multi-unit cell model and experimental results. A good agreement was observed between model computed results and experimental results.

“…However, the high temperature mechanical response of 3D five-directional braided composites with different braiding angles has not been reported. Mei et al [22] investigated the effect of carrier configuration on a 3D full five-directional rotary braided structure. To our knowledge, the high temperature mechanical properties and failure mechanism of 3D five-directional braided composites has not been reported.…”

Three-dimensional (3D) five-directional braided composites are extensively applied in aeronautics and national defense due to their integrity and structural superiorities. In this paper, 3D five-directional braided carbon/epoxy composites were manufactured, and the high temperature mechanical response and failure mechanisms of composites with braiding angles of 21° and 32° were studied. The out-of-plane compression tests of composites with different braiding angles were conducted at temperatures ranging from 25 °C to 180 °C. Then compression stress–strain curves, compression mechanical response, and failure modes of composites at high temperatures were analyzed and compared. The results show that compression stress–strain curves linearly increased at the initial stage and dropped at various degrees at different temperatures for composites with different braiding angles. The temperature and braiding angle were both important parameters affecting out-of-plane compression properties of 3D five-directional braided composites. Mechanical properties decreased with increasing temperature for both 21° and 32° specimens. Moreover, composites with a small braiding angle possessed higher properties at each temperature point. The morphologies manifested that the failures were a symmetric ±45° shear crack for 21° specimens and a thorough 45° shear crack for 32° specimens, and a 45° fracture weakened with increasing temperature.
