The authors have focused to review the impact properties of fibre reinforced composites particularly impact damage tolerance. Impact resistance, damage tolerance, composite failure and methods of assessing damage tolerance are presented. Furthermore, the approaches for improving damage tolerance such as fibre architectures resin system, and hybridisation using either yarn hybridisation or hybrid layers are discussed. In the end, a survey of modelling the impact damage of laminated composites is made by considering the inter-laminar and intra-laminar failures as key point for evaluating the response of laminates under impact loading.

The advantage of conventional technique lies in the flexibility of yardage production and composite may be developed by lamination or directly using 3D multilayer structure. Due to the stiffer nature of high-performance fibers, the conventional weaving technology causes damage of fibers in general and strength and modulus in particular. The warp creel is one of the main elements of weaving machine which is responsible for such fiber damage due to inflexible unwinding of fiber spool caused by friction. Therefore, in this research, a warp creel with novel features has been designed and manufactured to replace the conventional warp beam for smooth processing of high performance fibers. For this purpose, different parts of the proposed warp creel were designed and manufactured, including creel frame and adjustable spindles. These parts were ...

The slippage and mutual displacement of fibres relative to the yarn for analysis of the strain state of fibres in extended yarn are investigated. It is proposed for expression compressive transverse stress G, in our notation, to use the equation supposed in this work. The stress strain of fibres in extended yarn is examined and a comparison of the stresses between the cross-sectional and longitudinal directions is carried out. It is found that an increase in the twist angle leads to an increase in the compressive transverse stress of fibres in the centre of the yarn. It is also noticed that the axial stress strain depends on the twist angle of the yarn. The results obtained using this relationship are similar to those presented in previous studies. in staple yarn, migration, slippage and other phenomena occur. Kinematical and geometrical modifications made to the spinn...

This work is to attempt to this need. Shear behavior is key characteristic and play direct role to the performance of woven fabrics. In this study, three different 3D weave structures have been used to analyze the fabric shear rigidity. Shear analysis has been carried out in both directions using Kawabata evaluating system. Based on the results, a relationship of shear rigidity (G) and shear hysteresis are compared and analyzed in zero and 90o direction of fabric.

The area of PPC has been steered to high tech equipment made from plastic-based materials, which are derived from non-renewable sources and have a long life cycle expanding from hundreds to thousands of years, after their end of useful life. This paper reviews the information related to conventional plastic-based fibers, their properties, advantages, disadvantages, and applications in the battlefield, industry, automobiles, etc. This paper provides a basis for the selection of natural fibers and the replacement of conventional plastic-based fibers to reduce the plastic content in protective clothing or other composites. A comparative analysis of technological, environmental, economic and legal aspects of plastic-based and environment-friendly natural fibers is presented. Natural fiber-based composite protective cloth...

Nevertheless, the growth of bacteria within textile knitted mesh intersections can occur after surgical mesh implantation, causing infections. Thus, bacterial reproduction has to be stopped in the very early stage of mesh implantation. Herein, novel antimicrobial PP meshes grafted with β-CD and complexes with triclosan were prepared for mesh infection prevention. Initially, PP mesh surfaces were functionalized with suitable cold oxygen plasma. Then, hexamethylene diisocyanate (HDI) was successfully grafted on the plasma-activated PP surfaces. Afterwards, β-CD was connected with the already HDI reacted PP meshes and triclosan, serving as a model antimicrobial agent, was loaded into the cyclodextrin (CD) cavity for desired antibacterial functions. The hydrophobic interior and hydrophilic exterior of β-CD are well suited to form complexes with hydrophobic host guest molecules. Thus, the prepared PP mesh samples, CD-TCL-2 and CD-TCL-6 demonstrated excellent antibacterial properties against Staphylococcus aureus and Escherichia coli that were sustained up to 11 and 13 days, respectively. The surfaces of chemically modified PP meshes showed dramatically reduced water contact angles. Moreover, X-ray diffractometer (XRD), differential scanning calorimeter (DSC), and Thermogravimetric (TGA) evidenced that there was no significant effect of grafted hexamethylene diisocyanate (HDI) and CD on the structural and thermal properties of the PP meshes.

This always has attracted researchers and machines manufacturers to make new developments in process and machines. Air-jet is one of the leading and successful highest productive weaving machines. However, it is now well established that due to add of charges of compressed air, manufacturing cost of air-jet weaving machine is higher as compared with rapier and projectile weaving machines. This is why countries having energy issues do not prefer air-jet weaving machines comparing projectile weaving machines. In this regard, several researchers and machine manufacturers have continuously been working to improve the efficiency of air-jet weft insertion. However, industry practice is as important as design made by researchers. The aim of this research is to investigate the air consumption of air-jet weaving on industrial scale practice. In this study, five weaving machine of same manufacturer and model were select...

Nevertheless, the growth of bacteria within PP mesh pores after operation is a major reason of hernia recurrence. Secondly, pre-operative prophylaxis during mesh implantation has failed due to the hydrophobic nature of PP meshes. Herein, chitosan cross-linked and levofloxacin HCl incorporated, antimicrobial PP mesh devices were prepared using citric acid as a bio-based and green cross-linking agent. The inert PP mesh fibers were surface activated using O2 plasma treatment at low pressure. Then, chitosan of different molecular weights (low and medium weight) were cross-linked with O2 plasma activated surfaces using citric acid. Scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy, and Fourier transform infrared (FTIR) spectroscopy confirmed that chitosan was cross-linked with O2 plasma-treated PP mesh surfaces and formed a thin layer of chitosan and levofloxacin HC...
