“…However, the ability to arrest delamination crack will also be affected since the fracture toughness of thinner interleaves is lower [18]. It has been observed that all the delamination cracks have been arrested at the initial edge of the interleaved film ( Figure 4 and Figure 5).…”

A novel delamination damage control and management concept is demonstrated showing how, through selective placement of discrete thermoplastic film interleaves, it is possible to manipulate the formation of impact damage and control its subsequent propagation during compressive fatigue cyclic loading.This process has been shown to significantly improve the fatigue life of the composite panels tested by an average of 13 times. It is proposed that this method of controlling delamination damage growth may lead to lower weight damage tolerant composite designs resulting in more cost effective composite structures.2

“…To improve the ILFT, composite strips and/or tough adhesives are interleaved between ply interfaces to arrest delamination [105][106][107]. It was also reported that high strain rate and failure strains must be characterized by the interleaf layers [108,109]. However, resin-rich interleaves, which enhance the ILFT, also decrease fiber-dominated properties (modulus and tensile strength) as the fiber volume fraction is comparatively reduced [107].…”

Abstract:Composite materials are prone to delamination as they are weaker in the thickness direction. Carbon nanotubes (CNTs) are introduced as a multiscale reinforcement into the fiber reinforced polymer composites to suppress the delamination phenomenon. This review paper presents the detailed progress made by the scientific and research community to-date in improving the Mode I and Mode II interlaminar fracture toughness (ILFT) by various methodologies including the effect of multiscale reinforcement. Methods of measuring the Mode I and Mode II fracture toughness of the composites along with the solutions to improve them are presented. The use of different methodologies and approaches along with their performance in enhancing the fracture toughness of the composites is summarized. The current state of polymer-fiber-nanotube composites and their future perspective are also deliberated.

“…The delamination was observed to propagate along the oblique ply without any branching. It is assumed that the resin pocket ahead of the crack front locally increases the toughness due to the increase of resin rich interlayer thickness 28 . This ensured that the delamination followed the oblique 0° ply, which is oriented in the crack propagation direction 19,20 .…”
