“…This internal damage, due to more absorbed energy, may be attributed mainly to various failure mechanisms in the laminate such as fiber breakage, delamination, elastic and plastic deformation, friction, matrix cracking, impact face indentation, and back face splitting. 27 Generally, the elastic energy (the difference between impact energy and absorbed energy) has an opposite trend to the total absorbed energy and its share in the total impact energy is small in majority of the cases.…”

“…The SBS is a common test, among various other tests, used to measure ILSS due to its simplicity. 19,27,45 This test is also useful to assess the effective improvement of interlaminar resistance and failure mechanism of fabricated composite laminates. The typical stress-strain curves of prepared representative samples are shown in Figure 2(a).…”

“…25 Among these various approaches, inserting an interleave between adjacent carbon fiber plies has been extensively studied. 15 These interleaves may be either in the form of films/sheets 26,27 or nonwoven webs. 28 Interleaves consisting of nonwoven webs or membranes are mostly fabricated via electrospinning.…”

In this study, high-performance polyethylene (HPPE) fiber-based needle punched nonwovens were interleaved in cross-plied woven carbon fabric/epoxy composite laminates to enhance their interlaminar and impact properties. The placement of needle punched nonwoven interleaves exhibited considerable enhancement in interlaminar shear strength (ILSS), impact damage tolerance, and compression after impact (CAI) strength of laminates as evidenced by higher interlaminar strength, less absorbed energy, higher elastic energy, reduced damage degree, reduced out-of-plane deformation, higher loadbearing capacity, and higher residual compressive strength as compared to control sample. In particular, the composite laminate with placement of interleaves in alternating sequence between carbon plies resulted in 205.76% increase in ILSS and 129, 103 and 85% increase in CAI at 10, 25, and 40 J impact energy, respectively. Moreover, damaged surface area and out-of-plane deformation reduced to 38.75% and 62.5%, respectively for the same specimen impacted at 40 J energy. These results suggest that the HPPE fiber-based needle punched nonwoven interleaving can be adopted as a simple and low-cost approach compared with other interleaving techniques, to enhance the resistance to delamination, impact performance, and damage tolerance of traditional structural laminates.

In this report, networks of carbon nanotubes (CNTs) are transformed into composite yarns by infusion, mechanical consolidation and polymerization of dicyclopentadiene (DCPD). The microstructures of the CNT yarn and its composite are characterized by scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), and a focused ion beam used for cross-sectioning. Pristine yarns have tensile strength, modulus and elongation at failure of 0.8 GPa, 14 GPa and 14.0%, respectively. In the composite yarn, these values are significantly enhanced to 1.2 GPa, 68 GPa and 3.4%, respectively. Owing to the consolidation and alignment improvement, its electrical conductivity was increased from 1.0 × 105 S/m (raw yarn) to 5.0 × 105 S/m and 5.3 × 105 S/m for twisted yarn and composite yarn, respectively. The strengthening mechanism is attributed to the binding of the DCPD polymer, which acts as a capstan and increases frictional forces within the nanotube bundles, making it more difficult to pull them apart.

The low‐damage and high‐efficiency tight bonding of two inert materials, carbon nanotubes (CNTs) and carbon fibers (CFs), is implemented simply and mildly based on the secondary reaction platform role of polydopamine (PDA). The strong adhesion of PDA can fix varying masses of CNTs stably and uniformly on the surface of carbon fiber, which significantly augments the polar component and roughness of fiber surface. In the proposed control method, the interface shear strength and interlaminar shear strength of CF‐PDA6‐CNTs0.05 increase by ≈61.03% and 55.30% compared to desized CFs based composites. Remarkably, the improvement mechanism in the mechanical properties of the composites is analyzed by the transverse fracture morphology of the composites as well as thermodynamically.
