“…Also, the fracture toughness values increased for the same reinforcement fabric types, when the crack length was increased. A survey of literature on the effect of crack length on the fracture toughness has revealed that the findings presented in this article are in comply with the results already found by other authors . Table shows that each of natural fibers (or yarns) has different strength values.…”

Decreasing natural resources and increasing environmental destructions dispatch researchers to find more ecological solutions in material industry. Natural fibers have recently become an interesting topic as an alternative reinforcement material for fiber reinforced polymer composites for researchers. In this study; the effect of knitting density, natural fiber type, crack length, and fabric direction (wale or course) on the fracture strength and fracture toughness of laminated composites reinforced with natural fiber knitted fabric were investigated. For this aim, plain fabrics made of 50/50 bamboo/cotton, 50/50 viscose/cotton, and 50/50 modal/cotton blended yarns were knitted with three different knitting density. After that; bamboo/epoxy, viscose/epoxy, and modal/epoxy laminated composites were produced by using hand lay‐up method. Quasi‐static three‐point bending tests have been carried out on the single‐edge notched bending composite specimens, which have a crack in wale or course directions. Fractured surfaces investigated through the Scanning Electron Microscopy describing different failure mechanisms are also reported. Test results showed that fabric which knitted in cellulosic fibers, reinforced composites, had higher flexural strength and fracture toughness in the wale direction. It has also been observed that the knitting density and crack geometry affect the crack propagation behavior. POLYM. COMPOS., 40:217–228, 2019. © 2017 Society of Plastics Engineers

“…Fracture behavior of orthotropic materials is more complex because of nature of these materials. As well known, plastic zone formation during damage is not observed in brittle materials unlike ductile materials . As a consequence, crack in the brittle materials is more danger than the ductile materials in terms of durability of structures.…”

Cracks can occur in the composite structures during production, assembly, or usage. Environment temperature, deformation rate, and crack geometry have a direct influence on the fracture behavior of laminated composites. In this study, the fracture behavior of S-2 glass/epoxy composites having different crack geometry at different temperatures and deformation rates was investigated experimentally and numerically. Within the scope of the study, the fracture toughness (K) and strain energy release rate (G) values of samples with 5 mm crack geometry were calculated for the crack tip opening conditions in Mode I and Mode I/II. Fracture tests at different environmental temperatures were performed to investigate the effects of temperature on fracture behavior. Fracture tests were achieved at three different deformation rates, to exhibit the relationship between crack initiation and deformation rate. Also, the fracture behavior of S-2 glass/epoxy laminated composites was analyzed by using the finite element method (FEM). S-2 glass fabric reinforced composite is used as a new alternative to traditional building materials, especially in the aviation, space and military industries. The results obtained from the experimental and FEM studies of this composite structure showed that different environmental and loading conditions were effective on the fracture behavior of the composite structure.

“…2). When the applied normal stress reaches the failure stress, the stress intensity factors K I and K II become the critical stress intensity factor (K IC and K IIC ), which is taken as the fracture toughness of the composite specimens [30,31]. The stress intensity factors ahead of the crack tip for Arcan test sample are calculated by using Eq.…”

Due to the high synergistic effects of the components, hybrid composite materials are more advantageous than nonhybrid composite materials for advanced engineering applications. Additionally, knitted fabrics may have a different behavior than woven ones. Although the nonhybrid composites have only one reinforcing fiber type, the hybrid composites have multiple reinforcing fibers. In this chapter, fracture characterizations of laminated composites reinforced with intraply pure and hybrid knitted fabrics are experimentally and numerically investigated under different loading conditions. For this purpose, pure (100%) and hybrid fabrics (50-50%), which have 1 Â 1 rib-knitted structure, were knitted by using glass and carbon fibers. Also, hybrid fabrics were knitted in three different widths in order to investigate the effect of knitting pattern width on the fracture toughness. Fracture toughness and energy strain release rates of pure and hybrid Arcan test specimens were determined under mode I (0 o), mixed-mode I/II (30 o ,45 o ,and60 o), and mode II (90 o) loading conditions. Also, the J-integral method was used to determine the fracture toughness. Experimental and numerical results were found to be consistent. When the results obtained from pure and hybrid fabrics are compared, it is seen that hybridization had positive effects on the fracture strength of composite material compared to pure glass/epoxy material. Additionally, as the width of the pattern decreased, the fracture strength of the hybrid composites increased. In this respect, the hybridization processing should be done in the narrowest pattern width for higher resistance to fracture.
