Additive Manufacturing of Composites and Complex Materials

Abstract

Advanced composite materials form an important class of high-performance industrial materials used in weight-sensitive applications such as aerospace structures, automotive structures and sports equipment. In many of these applications, parts are made in small production runs, are highly customized and involve long process development times. Developments in additive manufacturing (AM) methods have helped in overcoming many of these limitations. The special topic of Additive Manufacturing of Composites and Complex Materials captures the state of the art in this area by collecting nine papers that present much novel advancement in this field. The studies under this topic show advancement in the area of AM of carbon fiber and graphenereinforced composites with high thermal and electrical conductivities, development of new hollow glass particle-filled syntactic foam filaments for printing lightweight structures and integration of sensors or actuators during AM of metallic parts. Some of the studies are focused on process optimization or modification to increase the manufacturing speed or tuning manufacturing techniques to enable AM of new materials.

Characterization of Microstructural and Mechanical Properties of 17-4 PH Stainless Steel by Cold Rolled and Machining vs. DMLS Additive Manufacturing

“…On the other hand, since the emergence of additive manufacturing technologies, barriers to design have been removed, and the way products are manufactured has changed dramatically [22]. Additive manufacturing (AM) operates on the principle of constructing a three-dimensional model layer by layer, facilitated by computer-aided design (CAD) software [23]. In the realm of metal printing technologies, prominent examples include laser metal fusion (LMF), selective laser melting (SLM), and direct metal laser sintering (DMLS) [24,25].…”

Braking performance of friction materials: a review of manufacturing process impact and future trends

“…It is increasingly used at the academic and industrial scale, in prototyping, adding material to existing parts (as in repair or hybrid manufacturing), and producing new pieces due to its ability to enhance the product's performances. 3D printed materials can be plastic, ceramic, metal/polymer matrix composites [152–157], and typically metals (aluminium alloys, nickel alloys, tool steels, stainless steels, maraging steel) [158]. The relevant advantages of AM Technique are simplicity of use, rapid production of reduced weight components, and environmental friendliness (low waste emission) [159,160].…”

Epoxy/hollow glass microsphere syntactic foams for structural and functional application-A review

“…3D printing of HGM was prepared by Dileep et al 26 with high-density polyethylene (HDPE) as a polymer matrix and the suitable printing parameters were enlisted. Jonathan et al 27 studied carbon fiber (CF) and graphene reinforced composites with high thermal and electrical conductivities, development of new hollow glass particle-filled SF filaments for printing lightweight structures and integration of sensors or actuators during additive manufacturing (AM) of metallic parts.…”
