“…From Figure 11, it is evident that the propagation fracture energy is higher than the initiation fracture energy for both types of the specimens, which complies with the literature. 40,55 From the Rcurve, it is evident that the propagation fracture toughness for the control specimens was almost similar to that of GnP reinforced specimens, which is due to the contribution of fibre bridging of control CFRPC.…”

Three‐point flexural fatigue behaviour and mode I interlaminar fracture toughness of the carbon fibre reinforced polymer composites (CFRPCs) modified by the addition of graphene nanoplatelet (GnP) were investigated. CFRPCs without any addition of nanoparticles were also tested as control samples. Fatigue life was characterized by the two parameter Weibull distribution function and predicted using the combined Weibull and Sigmoidal model. It was found that incorporation of very small amount (0.1%) of GnP in the epoxy polymer matrix improved mean and predicted fatigue life up to 155% and 190% (0.5 failure probability), respectively. The critical mode I interlaminar fracture toughness of the GnP reinforced composites was found up to 40% higher than the control samples. The improvement achieved by incorporating GnP is discussed in terms of crack deflection mechanism by nanoparticles and scanning electron micrograph images of the fracture specimens that revealed strong interfacial bonding in the nanoreinforced specimens.

“…Pratama et al [ 19 ] provided guidelines for determining the composition of healing agent solutions of three different multimaleimides to optimize the healing performance of epoxy–amine polymer. Jony et al [ 20 ] studied the bio‐mimetic repeatable self‐healing capability of thermoplastic healing agent poly‐caprolactone together with shape memory polymer in thermosetting fiber reinforced polymer composites. Bolimowski et al [ 21 ] investigated the behavior of self‐healing microcapsules separately containing the epoxy resin and imidazole hardener in CFRP composites.…”

Since delamination always occurs in the laminate structures of fiber reinforced polymer composites in engineering applications, developing self‐healing composites has become more and more important nowadays, especially for large‐scale composite equipment, which is difficult to maintain when in service. In this paper, the micromechanical finite element (FE) models are developed for the polymer matrix composites containing self‐healing microcapsules. Based on mesoscale FE simulation and cross reference to related experimental results, we firstly reveal the rupture mechanism of microcapsules, in which the interaction between the microcapsules and microcracks propagated in the resin matrix is investigated by using the extended finite element method in ABAQUS. The mesoscale characteristics of the self‐healing agent, dicyclopentadiene, during the healing process, are revealed with the help of the fluid–solid coupling FE module. Especially, the dynamic filling mechanism of the self‐healing agent within the microcrack planes is physically interpreted by the use of the capillary effect and contact angle principle. Finally, the healing efficiencies of self‐healing composites with different microcapsule sizes and volume fractions are quantitatively evaluated via the virtual mechanical tests of fracture toughness. To be emphasized is that most of the simulation results obtained in this work have exhibited good agreements with the corresponding experimental data, showing a robust reliability of our FE models.

The three-dimensional molded interconnected device (3D-MID) has received considerable attention because of the growing demand for greater functionality and miniaturization of electronic parts. Polymer based composite are the primary choice to be used as substrate. These materials enable flexibility in production from macro to micro-MID products, high fracture toughness when subjected to mechanical loading, and they are lightweight. This survey proposes a detailed review of different types of 3D-MID modules, also presents the requirement criteria for manufacture a polymer substrate and the main surface modification techniques used to enhance the polymer substrate. The findings presented here allow to fundamentally understand the concept of 3D-MID, which can be used to manufacture a novel polymer composite substrate.
