Special Issue Information

Dear Colleagues,

The fabrication of composites using lasers has been established as an easy, fast, flexible, controllable, and green method for the synthesis of materials for a range of applications in different fields.

Composites can be fabricated by laser irradiation of photo/thermo-sensitive materials. Selective laser sintering or melting of metals, polymers, carbon-based and other materials in powdered form leads to the fabrication of composites. Composites can be fabricated by laser surface cladding of nanoparticle-coated metals also under external stimulus, such as ultrasonic vibration, magnetic field, or others. Composites can be fabricated by laser ablation of a bulk target material immersed in a monomer or polymer-doped solvent via the incorporation into the matrix of nanoparticles synthesized by the target laser ablation. Alternatively, nanoparticles can be synthesized by laser ablation of the bulk target material in a solvent, and then the colloidal solution mixed with a polymer, leading to the fabrication of a composite. Laser irradiation of a nanoparticle colloidal solution can lead to the fabrication of composites due to laser-induced joining of nanoparticles.

Journal of Composites Science invites papers for a Special Issue titled "Laser Fabrication of Composites". Experimental and theoretical articles will be accepted regarding the methods/methodology for the laser fabrication of composites, modeling of the laser beam–material interaction, chemistry of the laser fabrication of composites, material performance of laser-fabricated composites, industrial scale-up of the method, and interfacing of the laser fabrication of composites with characterization techniques. Topics of interest include, but are not limited to, the following:

  • Laser fabrication of composite scaffolds;
  • Laser additive manufacturing of composites;
  • Laser ablation nanoparticle–polymer composites;
  • Laser fabrication of graphene-based composites;
  • Laser fabrication of 2D material-based composites;
  • Laser fabrication of fiber-based composites;
  • Theoretical modeling;
  • Laser fabrication of magnetic composites;
  • Laser fabrication of functional composites;
  • Laser fabrication of natural material-based composites.

During LATP (laser automated tape placement), the compaction roller contacts the prepreg and affects the pressure distribution directly. Moreover, the design parameters of the roller are optimized with the aim of improving pressure uniformity. This paper examines the impact of the contact line and surface that depends on the compaction force, the design of the roller, the angle of inclination and the angle of inclination of the strip. These factors significantly affect the expansion of the tape, and it is important to determine it to avoid side effects in the production of composites (formation of gaps or overlaps). Their presence increases the percentage of pores of the final material and thus reduces the mechanical properties. The results show that the pressure uniformity can be improved significantly by design optimization of the roller, which indicates that higher bond quality between layers is achieved. The lower the speed and higher the compact force in this technology give better intimate contact with a lower percentage of voids and good mechanical characteristics. Full article

Additive manufacturing (AM), a 3D printing technique that manufactures components by sequential addition of powder, has massively reshaped the manufacturing and engineering sectors from batch production to manufacturing customized, innovative, state-of-the-art, and sustainable products. Additive manufacturing of aluminum alloys by selective laser melting (SLM) is one of the latest research trends in this field due to the fact of its advantages and vast applications in manufacturing industries such as automobiles and aerospace. This paper investigated the surface and dimensional quality of SLM-built AlSi10Mg parts using a response surface method (RSM) and found the influence of the wall thickness and process parameters (i.e., laser power, scanning speed, hatch distance) on the pieces. Thin-walled test specimens of AlSi10Mg alloy were manufactured with different combinations of process parameters at three wall thicknesses: 1.0 mm, 2.0 mm, and 3.0 mm. The Minitab DOE module was used to create 27 different configurations of wall thickness and process parameters. The samples’ surface roughness and dimensional accuracy were investigated, and the findings were evaluated using the ANOVA technique. The regression model and the ANOVA technique showed high precision and had a particular reference value for practical engineering applications. Full article

In our previous studies, we have developed a wet process, denoted as laser surface implanting (LSI), to synthesize a copper/single-walled carbon nanotube (Cu–SWCNT) metal nanocomposite. The nanostructure of this Cu–SWCNT composite was shown to contain discernable SWCNT clusters in nanosizes inside the copper matrix. Its hardness could achieve up to three times that of pure copper, verified by micro-hardness and nano-hardness tests. A focus ion beam bombardment test and a plane strain compression test show 2.5 times toughness improvement for the Cu-SWCNT composite. Based on these strength improvements, two potential applications for the Cu-SWCNT nanocomposite are proposed and their feasibilities are verified using specially design test rigs. The first application is related to creating long lasting electric contacts. The result shows that the Cu-SWCNT nanocomposite is highly wear-resistant. The contact area of the simulated electric contacts increases after repeated impact loading, which potentially could lower the contact resistance. The second application is to use the Cu-SWCNT implants as high strength spot weld for joining copper foils. A smaller weld with a higher strength reduces the power requirement of the laser and, consequently, the thermal distortion for higher-dimensional precision. The specially designed test rig for the weld strength characterization is a new contribution, providing a new testing capability for small and non-homogeneous samples not suitable for a standard tensile test machine.
