“…This is because of the higher melt viscosity and rapid cooling of the plastics melt while the mold cavity is filling. Consequently, MID design for highly filled thermally conductive compounds is always trade-off between the modified properties and workability of the materials [ 187 , 188 , 189 , 190 , 191 ].…”

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.

“…due to their low cost and weight, high specific strength, ease of processing, and resistance to decomposition under various conditions. 1–11 Since the last two decades, efforts have been made to enhance the strength of fiber-reinforced polymer composites by incorporating nanomaterials to widen the spectrum of their applications. 12–14 Amongst the various nano-fillers for polymer nanocomposites (nanoclay/silicate platelets, carbon nanotubes, Kevlar nanofibers, silica nanoparticles etc.…”

“…In the last few years, research has emphasized on compatibilization of different constituents of fiber-reinforced nanocomposites for improved interfacial bonding among them and hence superior mechanical properties of composites. 1,3–5,13,17,21,23–25 Jung and Sodano 42 added silane-treated nano-aramid fibers to epoxy nanocomposites and observed significant improvements in tensile strength, tensile modulus, and fracture toughness. Limited literature is available on GFRCs reinforced with silanized nanoclay.…”

This research examines the effect of nanoclay silanization/compatibilization on the izod impact strength and tensile properties of epoxy-clay-based glass fiber reinforced composites (GFRCs). As per the existing literature, a key step in silanization of clay is washing of the silanized clay with acetone to remove the excess of silane molecules. However, contrary to this, the present research shows that acetone washing of the silanized clay lowers the tensile properties. GFRCs containing 2 phr nanoclay were processed. Three different montmorillonite clays were used in the initial investigations (two organically modified nanoclays designated as “CA” and “IE” and one unmodified nanoclay designated as “PG”). Silane concentration was varied in the range of 100–400% as proportion of nanoclay loading (i.e. 1X, 2X, 3X, and 4X). Silanization was validated by FTIR. XRD/TEM revealed increased d-spacing for silanized nanoclay and a partially exfoliated clay morphology in GFRCs. Highest izod impact strength (37% higher than the reference GFRC) without any loss in tensile properties was observed for GFRC reinforced with acetone washed 2X silanized “PG” nanoclay. GFRCs reinforced with silanized unwashed nanoclay (3X) showed 27% improvement in izod impact strength with significantly improved tensile strength (16% higher than the reference sample).

“…33 Similarly, boron nitride (BN) helps to enhance mechanical properties and thermal conductivity of composites. 34 To obtain superior features from composite materials, carbon nanotubes (CNTs), 35 BN, 34 clay 36 and/or nano-SiC 37 are introduced into the composite. 38 It is therefore necessary to investigate drilling performance of these hybrid composite materials to determine suitable drilling conditions; however, there is very limited number of studies recently published on drilling performance of carbon nanotube reinforced composite 39 and no study was found on drilling of BN reinforced composite materials in open literature.…”

The reinforcements of nanoparticles have an important role in improving the machinability of nanocomposite materials. Except for the known nanoparticles such as carbon nanotube, graphene, nanoclay, etc., the effect of boron nitride reinforcement on the machinability of composite materials are a recent research topic. In this study, boron nitride nanoparticle was introduced to the matrix resin that brings about additional strength and enhancement in thermal and mechanical properties of the composite. Though it was confirmed that this composition enhances the focused properties, it is necessary to investigate drilling performance of these composite and identify the effects of this boron nitride nanoparticle on machinability of carbon fiber epoxy nanocomposite considering thrust force, delamination factor, etc. Accordingly, while the thrust force is increased by reinforcement of the boron nitride nanoparticles, on the contrary of literature, delamination factor is tend to reduce as compared with reference composite. This experimental study shows the addition of boron nitride nanoparticles help to reduce delamination factor of carbon fiber epoxy nanocomposite. In addition, hole surfaces and drilling mechanism analyzed with optical and scanning electron microscope about damage estimation.
