“…The tested control samples displayed an average crack initiation toughness ( G Ic ) value of 206.6 J/m 2 which is comparable to other studies done on glass fiber composites. 16,17 With the addition of short carbon fibers in-between the laminates, the G Ic value increased for all composite types. The introduction of carbon fibers increases the extent of crack bridging between the laminates of the composite which resists crack initiation and propagation.…”

A detailed experimental study is performed for piezo resistance damage sensing on conductive glass fiber/epoxy composites under mode-I fracture conditions. The conductive composites are fabricated by homogeneously dispersing carbon nanotubes (CNTs) within the epoxy matrix and electro-flocking short carbon fibers onto the laminates along with a vacuum infusion process. A parametric study is done on the in-situ damage sensing properties by varying the carbon fiber lengths (150 µm and 350 µm) and the carbon fiber areal densities (500, 1000, 1500, and 2000 fibers/mm2). The change in resistance is captured with a four-point probe measuring methodology by measuring the resistance through the thickness of the composite. The crack initiation toughness value of the composites containing carbon fibers showed improvement over control composites. Composites containing 350 µm length carbon fibers and 2000 fiber/mm2 not only showed the best crack initiation toughness but also provided sensitive network for detecting crack growth.

“…Fiber crimp causes local stress on composites-hence, the matrix may crack due to the debonding in the fiber interface. Consequently, numerous studies were conducted to discover the causes of delamination in woven fabricreinforced composites [72][73][74]. The mechanical properties of WFCs are influenced by the surface treatments of the biofibers.…”

Fabric-based laminated composites are used considerably for multifaceted applications in the automotive, transportation, defense, and structural construction sectors. The fabrics used for composite materials production possess some outstanding features including being lighter weight, higher strength, and lower cost, which helps explain the rising interest in these fabrics among researchers. However, the fabrics used for laminations are of different types such as knit, woven, and nonwoven. Compared to knitted and nonwoven fabrics, woven fabrics are widely used reinforcement materials. Composites made from fabric depend on different properties such as fiber types, origin, compositions, and polymeric matrixes. Finite element analysis is also further facilitating the efficient prediction of final composite properties. As the fabric materials are widely available throughout the world, the production of laminated composites from different fabric is also feasible and cost-effective. This review discusses the fabrication, thermo-mechanical, and morphological performances of different woven, knit, and nonwoven fabric-based composites.

“…The delamination behavior of laminated composites is a complex phenomenon due to the formation of FPZ at the crack tip, especially in the mixed mode I/II loading. Due to these complications, the first criteria presented in this field were based on curve fitting of experimental data [10][11][12][13][14]. Most of these empirical criteria are old, and there is some material constant in these criteria that must be obtained by experiments for each crack configuration.…”

In this paper, by considering the absorbed energy in the fracture process zone and extension of the minimum strain energy density theory for orthotropic materials, a new mixed mode I/II failure criterion was proposed. The applicability of the new criterion, to predict the crack growth in both laminated composites and wood species, was investigated. By defining a suitable damage factor and using the mixed mode I/II micromechanical bridging model, the absorbed energy in the fracture process zone was considered. It caused the new criterion to be more compatible with the nature of the failure phenomena in orthotropic materials, unlike available ones that were conservative. A good agreement was obtained between the fracture limit curves extracted by the present criterion and the available experimental data. The theoretical results were also compared with those of the minimum strain energy density criterion to show the superiority of the newly proposed criterion.
