“…Natural fibers are known to be abundant, have low density, inexpensive, readily available from renewable sources and have shown significant performance in term of strength and stiffness enhancement [2,3]. The density of natural fibers is similar to their plastic counterparts, which are usually 40 to 50% lower than the density of glass fiber [4,5]. The industrial use of natural fiber has not only been driven by cost reduction, but also by other issues related to overall environmental awareness.…”

Sugar palm [Arenga pinnata (Wurmb.) Merr] fiber reinforced unsaturated polyester resin composites with 0°, 45°, and 90° fiber different orientations were prepared and tested. The composites were characterized for tensile, flexural, impact and compression properties using ASTM D3039, ASTM D790, ASTM D250, and ASTM D3410 standards, respectively. For the thermal characterization, dynamic mechanical analysis (DMA) was conducted to characterize the on storage modulus (E'), loss modulus (E'') and damping behavior (tan δ) of the composites. The highest mechanical performance of composites was achieved at 0° of fiber orientation composites followed by 45° and 90° fiber orientations. The fiber loading was insignificant for the 90° fiber orientation as the properties were inconsistent. The theoretical value of modulus from the tensile test was calculated using rules of mixture (ROM) and compared with the experimental values for all composites specimens. This research showed that the optimum properties occurred at 30 wt % fiber loading as reflected by the superior tensile and flexural strengths. The optimum properties of compression, impact, storage modulus and better damping properties were achieved at 40 wt % fiber loading.

“…Several simplified Global Load Sharing (GLS) models have been developed and used to do parametric studies on the effects of fibre hybridization in composite materials. Rajan and Curtin [16] developed a GLS theory to guide the design of fibre reinforced hybrid composites with superior mechanical properties to non-hybrid composites. The authors concluded that for hybrid composites with a low volume fraction of LE fibres it is possible to increase the composite's stiffness and pullout stress without compromising the tensile strength and strain of the material.…”

Three different models with increased complexity to study the effects of hybridization on the tensile failure of hybrid composites are proposed. The first model is a model for dry bundles of fibres based on the statistics of fibre strength. The second is a model for composite materials based on the multiple fragmentation phenomenon. Lastly, a micromechanical numerical model is developed that considers a random distribution of fibres and takes into account the stochastic nature of fibre strength. This study aims to understand the controlling factors that lead to pseudo-ductility, as well as establish the sequence of failure mechanisms in hybrid composites under tensile loadings.

“…These were relatively simple and required strong assumptions, but nevertheless already captured some basic influencing parameters. In the past decade however, new and more advanced models started appearing [ 31 , 45 , 46 , 47 , 48 , 49 ]. These models confirmed some of the conclusions of the earlier models, but also shed new light on others.…”

“…The initial models were not able to separate both of the effects either [ 39 , 43 , 54 , 55 , 56 , 57 ]. Later developments based on the global load sharing models had the same limitation [ 48 , 49 ]. Some of the more recent modelling results, however, can separate both effects, and their conclusions are unanimous: a better dispersion increases the hybrid effect [ 45 , 47 ].…”

Increasing the efficiency of wind turbines will be vital for the wind energy sector to continue growing. The drive for increased efficiency is pushing turbine manufacturers to shift from glass fibre composite blades towards carbon/glass fibre-hybrid composite blades. This shift brings significant challenges in terms of optimising the design and understanding the failure of these new blade materials. This review therefore surveys the literature on fibre-hybrid composites, with an emphasis on aspects that are relevant for turbine blade materials. The literature on tensile, flexural, compressive, and fatigue performance is critically assessed and areas for future research are identified. Numerical simulations of fibre-hybrid composites have reached a reasonable maturity for tensile failure, but significant progress is required for flexural, compressive, and fatigue failure. Fatigue failure of fibre-hybrid composites in particular, requires more careful attention from both a modelling and experimental point of view.
