The delamination behavior of glass-carbon hybrid laminate with glass and carbon fiber on either side of the mid-plane was studied using double cantilever beam test. The stacking sequence and fiber orientation of the hybrid laminate was taken as [G 0 /G 135 /G 90 /G 45 /C/C//G/G/G 45 /G 90 /G 135 /G 0 ]. Three different laminates were obtained by changing the fiber orientation of the mid-layers as C/C//G/G. Laminates were prepared by hand lay-up technique and post cured by compression. The test was conducted as per ASTM standard D5528. The strain energy release rate G Ic calculated using modified beam theory method was found to be higher for the laminate with mid-layers as C 90 //G 0 in comparison with that of the other two laminates. Fractographic analysis of the delaminated surfaces using scanning electron microscope indicates hackles, striations and fiber fracture. Hackles that provides more resistance to crack propagation leading to increase in inter laminar fracture toughness are observed in the glass fiber side of the specimen with C 90 //G 0 interface.

“…The composites show better physicochemical properties if suitable interactions between the fibre and the matrix are provided [68,98]. Furthermore, fibre types, length, diameter, density, modulus, strength, fibre orientation [99][100][101] and weave structures [102][103][104] significantly control the mechanical properties of NFRCs. While NFRCs are fabricated using the hydrophilic cellulosic fibres and the hydrophobic polymer matrices, very often they result in poor interfacial adhesion [105] and consequently poor mechanical properties [106][107][108].…”

The increasing global environmental concerns and awareness of renewable green resources is continuously expanding the demand for eco-friendly, sustainable and biodegradable natural fibre reinforced composites (NFRCs). Natural fibres already occupy an important place in the composite industry due to their excellent physicochemical and mechanical properties. Natural fibres are biodegradable, biocompatible, eco-friendly and created from renewable resources. Therefore, they are extensively used in place of expensive and non-renewable synthetic fibres, such as glass fibre, carbon fibre and aramid fibre, in many applications. Additionally, the NFRCs are used in automobile, aerospace, personal protective clothing, sports and medical industries as alternatives to the petroleum-based materials. To that end, in the last few decades numerous studies have been carried out on the natural fibre reinforced composites to address the problems associated with the reinforcement fibres, polymer matrix materials and composite fabrication techniques in particular. There are still some drawbacks to the natural fibre reinforced composites (NFRCs)—for example, poor interfacial adhesion between the fibre and the polymer matrix, and poor mechanical properties of the NFRCs due to the hydrophilic nature of the natural fibres. An up-to-date holistic review facilitates a clear understanding of the behaviour of the composites along with the constituent materials. This article intends to review the research carried out on the natural fibre reinforced composites over the last few decades. Furthermore, up-to-date encyclopaedic information about the properties of the NFRCs, major challenges and potential measures to overcome those challenges along with their prospective applications have been exclusively illustrated in this review work. Natural fibres are created from plant, animal and mineral-based sources. The plant-based cellulosic natural fibres are more economical than those of the animal-based fibres. Besides, these pose no health issues, unlike mineral-based fibres. Hence, in this review, the NFRCs fabricated with the plant-based cellulosic fibres are the main focus.

ÖzTabakalar arası çatlak ve kırılma, tabakalı kompozit malzemelerde çokça karşılaşılan bir hasar türüdür. Ayrılma modu tabakalar arası kırılmanın en kolay gerçekleştiği ve tabakalar arası kırılma tokluğunun en düşük olduğu kırılma modudur. Mode I Interlaminar Fracture Behaviour of Carbon/Epoxy Laminated Composites under Different Temperatures AbstractInterlaminar fracture of a laminated composite material is the damage resistance of the material to cracks located at interface. Mode I interlaminar fracture takes place and damages composites more easily than other modes since it is frictionless. In this study, the effect of ambient temperature to mod I interlaminar fracture toughness of carbon/epoxy laminate was studied. It is found out that if the ambient temperature decreases under 0 o C, Mod I interlaminar fracture toughness decreases also. However fracture behavior doesn't change and R-curve behaviors of laminates are similar under the 23 o C and below. For higher ambient temperatures than 23 o C, it is concluded that glass transition temperature (T g ) of epoxy matrix is key parameter and the crack doesn't propagate if the temperature is close to T g . Fracture characteristics of the laminate are so different under the temperatures higher than T g .
