Review of hybrid composites fatigue

Hybrid composites become popular and are today used in a large number of contemporary structural applications. When compared to non-hybrid composites, hybridization offers additional benefits since the mixing of cheaper, low-quality fibers, with more expensive fibers of higher quality can improve the properties of a composite without significantly affecting the cost. Among of improvements resulted from the hybridization is the fatigue behavior, although this has not yet been thoroughly investigated for a wide range of hybrid composites. This review article summarizes and discusses the existing works on the fatigue behavior of synthetic and natural fiber reinforced (FRP) hybrid composites, as well as fiber metal laminates (FMLs).

Natural fiber

Natural fibers or natural fibres (see spelling differences) are fibers that are produced by geological processes, or from the bodies of plants or animals. They can be used as a component of composite materials, where the orientation of fibers impacts the properties. Natural fibers can also be matted into sheets to make paper or felt. The earliest evidence of humans using fibers is the discovery of wool and dyed flax fibers found in a prehistoric cave in the Republic of Georgia that date back to 36,000 BP.

Carbon fibers

Carbon fibers or carbon fibres (alternatively CF, graphite fiber or graphite fibre) are fibers about in diameter and composed mostly of carbon atoms. Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high-temperature tolerance, and low thermal expansion. These properties have made carbon fiber very popular in aerospace, civil engineering, military, motorsports, and other competition sports.

Metal matrix composite

In materials science, a metal matrix composite (MMC) is a composite material with fibers or particles dispersed in a metallic matrix, such as copper, aluminum, or steel. The secondary phase is typically a ceramic (such as alumina or silicon carbide) or another metal (such as steel). They are typically classified according to the type of reinforcement: short discontinuous fibers (whiskers), continuous fibers, or particulates. There is some overlap between MMCs and cermets, with the latter typically consisting of less than 20% metal by volume.
