“…Figure 1 shows that, as expected [16], tensile strength of the sisal composite was lower than the hybrids, which was lower than that of the pure glass one. The tensile strength of Since all composites were built with the same number of glass and sisal layers, and all layers are subjected to the same deformation during testing, the various layers in each composite appeared to share the total applied load in a similar way, and not even the asymmetrical ones were particularly less efficient.…”

This study focused on the mechanical properties of pure sisal, pure glass, and hybrid sisal/glass compression-molded composites, in which various stacking sequences of fiber mat layers were used. It is shown that hybridization originated a material with general intermediate properties between pure glass and pure sisal. However, the importance of controlling the stacking sequence to enhance properties was evident. For instance, to optimize flexural behavior, there must be glass fibers mainly on the top and bottom surfaces. Furthermore, depending on the type of loading and stacking sequence, some hybrid composites may show properties very close to those of pure glass.

“…As detailed in the recent review papers by Jawaid and Khalil [69] and Nunna et al [147], natural fibre hybrid composites are often a combination of a natural fibre with another natural fibre [95,96,[148][149][150] or with glass fibre [107,142,148,[151][152][153][154][155][156][157]. The latter is more common, as it allows larger improvements in mechanical properties.…”

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.

“…Fiber additives are often applied to increase the mechanical strength of the materials. The natural fibers and flours made by grinding have been frequently applied to the polymers [3]. The natural fiber/flour-reinforced composites have attracted the attention of many scientists in the field of composite materials, because they have lot of advantages.…”

Rigid PVC wood flour composites were prepared with various volume fractions of wood flour to investigate the effect of the structure properties on the fractural and tensile behavior. During the mixture preparation the first question is the compatibility of the wood flour additive with the rigid PVC and the safe concentration range of the additive. The second question is the fractural behavior of the composites. Accordingly, the 300-400 micrometer particle size beech wood content was varied using 15, 20, 25 parts per weight of the polymer matrix. Since both the PVC and the major components of the beech wood (cellulose and lignin) are polar, we did not use a coupling agent between the polymer and the natural filler. Thus, the properties of the composites as function of concentration can be examined. The usual mechanical properties, such as tensile strength, elongation at break and so-called compact tensile fracture mechanical analysis was also performed. It has been found that the composites could be safely processed with up to 25 parts by weight wood content. However, the properties of 25 parts by weight filler content sample already showed a decrease in strength properties. We also tried to improve the fracture mechanical properties with fibrous (1 cm long) natural filler. In this case 20 parts by weight of wood flour content with one, three and five parts by weight hemp fiber were used in the PVC polymer matrix. The tests results showed that these fibrous fillers neither decrease nor improve the mechanical properties. The raw measurement results were evaluated according to the critical stress intensity factor (Kc) and the critical crack propagation energy (Gc). Ultrasound propagation measurements are in progress trying to determine the effect of structural changes and interactions at increased hemp fiber content.
