Special Issue Information

Dear Colleagues,

Fiber-reinforced polymer and ceramic composites, which are extensively used in the automobile, marine, and aviation industry can suffer from delamination due to production defects, the impact of hail and birds, overloading, and incorrect machining operations, etc. Components made of fiber-reinforced polymer and ceramic composites with reduced delamination may lose stiffness or provide a path for water ingression, and with delamination growth, ultimately an entire component failure may occur. The most dangerous form of failure of the component or structure made of fiber-reinforced polymer and ceramic composites is delamination. Therefore, it is crucial to investigate the fracture properties of fiber-reinforced polymer and ceramic composites before using them in these industries. Though several standard fracture mechanics test methods are available in the scientific world, the development of these methods or the introduction of new methods to determine the delamination growth resistance, or fracture toughness of fiber-reinforced polymer and ceramic composites are still promising areas of study due to their high demand.

The aim of this Special Issue is to focus on collecting recent research studies and review papers on fracture mechanics and the improvement of test methods to determine Mode I, Mode I, Mode III, or mixed-mode delamination growth of fiber-reinforced polymer and ceramic composites. Moreover, the editors invite research works to be published in this Special Issue regarding finite element model and the simulation of fracture tests such as cohesive zone modeling. Any other experimental, theoretical, and numerical work associated with the mechanism of delamination growth in fiber-reinforced polymer and ceramic composites will be a good fit with the scope of this Special Issue.

In this study, the different effects of weave structure on the comfort properties of fabrics and the mechanical properties of fiber-reinforced composites were investigated. Fabrics were developed using one type of material (flax spun yarn) in the warp direction and three different materials (flax, sisal and cotton spun yarn) in the weft directions. Four different types of weaves (plain, twill, matt and mock leno) were produced in each type of material. Twelve specimens were produced on a sample weaving machine. These fabrics with multiweave combinations give the wearer a comfort zone for sportswear and outdoor applications. These fabrics maintain the temperature of wearers in extreme weather conditions. But these weaves have different effects when interlaced with different types of weft yarns. Air permeability, overall moisture management, stiffness and thermal resistance were investigated for these fabric specimens. The hybrid fabric produced with pure flax warp and weft cotton/sisal exhibited the highest value of air permeability, overall moisture management capability and thermal resistance followed by flax–sisal and flax–flax. The hybrid fabric produced with the mock leno weave also presented a higher value of air permeability compared to the twill, mat and plain weaves. Bending stiffness was observed to be higher in those fabrics produced with flax/sisal compared to pure flax and flax–cotton. The outerwear fabric produced with a blend of flax yarn in the warp and cotton/sisal spun yarn in the weft exhibited improved properties when compared to the fabric produced with flax/sisal and pure flax yarns. In composites, flax/flax showed enhanced mechanical properties, i.e., tensile and flexural strength. In other combinations, the composites with longer weaves possessed prominent mechanical characteristics. The composites with enhanced mechanical properties can be used for window coverings, furniture upholstery and sports equipment. These composites have the potential to be used in automotive applications. Full article
