“…Since the impact face is loaded in compression and the other face is loaded in tension, the damage mechanisms can be different. Surprisingly, the conclusions of Jang et al [100] seem to contradict with the conclusions of Sayer et al [98] and Park and Jang [99]. This is most likely caused by differences in the damage mechanisms, which are triggered by differences in the materials and their interfaces.…”

Fibre-reinforced composites are rapidly gaining market share in structural applications, but further growth is limited by their lack of toughness. Fibre hybridisation is a promising strategy to toughen composite materials. By combining two or more fibre types, these hybrid composites offer a better balance in mechanical properties than non-hybrid composites. Predicting their mechanical properties is challenging due to the synergistic effects between both fibres. This review aims to explain basic mechanisms of these hybrid effects and describes the state-of-the-art models to predict them. An overview of the tensile, flexural, impact and fatigue properties of hybrid composites is presented to aid in optimal design of hybrid composites. Finally, some current trends in fibre hybridisation, such as pseudoductility, are described.

“…In literature there are many works related to these composites [11][12][13][14][15][16] but very few regarding hybrid composite reinforced by natural fibers and carbon types. 17 One of the most recent applications of the latter is regarding the realization of an ecologic prototype boat named 'Araldite,' which represents the smallest offshore racing boat (hull length ¼ 6.5 m, hull width ¼ 3 m, weight ¼ 750 kg, sail surface ¼ 120 m 2 ), which can sail the Atlantic sea.…”

In this work, the influence of an unidirectional carbon fabric layer on the mechanical performances of bidirectional flax fabric/epoxy composites used for structural applications was studied. Two different bidirectional flax fabrics were used to produce flax fabric reinforced plastic (FFRP) laminates by a vacuum bagging process: one is normally used to make curtains; the other, heavier and more expensive than the previous one, is usually used as reinforcement in composite structures. In order to realize hybrid structures starting from FFRP, an unidirectional UHM carbon fabric was used to replace a bidirectional flax fabric. Tensile and three-point bending tests were performed to evaluate the mechanical properties of the laminates investigated (both FFRP and hybrids). Furthermore, the mechanical behavior of the different bidirectional flax fabrics was analyzed by carrying out tensile tests. The experimental tests showed that the structures reinforced with flax fabrics, normally used to make curtains, present better flexural properties than that of others while, in tensile configuration, these last show higher modulus and strength. Moreover, both FFRP laminates show low mechanical properties, which do not allow their use in structural applications while the presence of one external layer of unidirectional carbon involves remarkable increase in their properties. According to this study, the hybrid composites realized could be used in several structural applications (i.e., nautical and automotive).

“…Rajkumar et al (2012) studied the effect of repeated low-velocity impacts on glass fiber metal composites, and established that the peak load, impact energy, and failure strain decreased with increasing number of impacts. Sayer et al (2010) investigated the impact response of hybrid composite plates (glass-carbon/epoxy) with different stacking sequence for impact energies ranging from 25 to 75 J, and concluded that fiber fracture was the dominant failure mode as the impact energy increased. Murat and Rahman (2017) tested woven carbon/epoxy prepreg laminates at different impact energy levels in the range of 1-10 J, and observed that thicker samples manifested higher resistance to impact damage and the damage area increased with increasing impact energies.…”

The rise in demand and interest in Arctic exploration has brought new challenges with regard to the mechanical behavior of lightweight offshore structures with fiber-reinforced composite materials. These materials experience drastic changes and degradation in their macro-and microstructures when exposed to seawater and cold temperatures during service. Therefore, it is critical to have a detailed comprehension of the mechanical behavior and failure mechanisms of these materials in Arctic conditions. Within the scope of the current study, low-velocity repeated impact behavior of carbon fiber/vinyl ester composites in Arctic temperature (−50 • C) is investigated. Impact responses, such as the contact force, displacement and absorbed energy, at four impact energies of 20, 25, 30 and 35 J under repeated impact loading until perforation are determined at −50 • C and compared against those at room temperature (25 • C). The number of impacts required for perforation, the rate of reduction in impact force, the degree of damage and the failure mechanisms change significantly with varying impact energies and in situ ambient temperatures, and they are elucidated in detail in this paper.
