Special Issue Information

Dear Colleagues,

Composite materials have become an alternative material to supersede metal alloys in structural applications due to their lightweight, high strength-to-weight ratio and corrosion resistance characteristics. Furthermore, composite materials offer the flexibility to tailor their functional properties since they are developed by combining two or more distinct phases. In modern technology, the continuous growth and evolution of composite materials have led to diversity in such materials. In order to enhance structural performance, holistic exploration of novel materials and optimization of the existing materials are essential.

Original research articles based on experimental investigation and/or finite element modeling related to any kind of polymer composite materials, including synthetic, natural and hybrid fiber-reinforced composites, are invited to submit. The scope of this research topic includes, but is not limited to:

  • Composite materials;
  • Biocomposites;
  • Laminate composites;
  • Hybrid composites containing natural fibres and synthetic fibres;
  • Fiber treatment and optimization;
  • Nanocomposites;
  • Structural applications;
  • Fabrication (filament winding, pultrusion, VARTM and additive manufacturing);
  • Life cycle assessment;
  • Composite recycling;
  • Weathering;
  • Physical properties;
  • Flammability;
  • Mechanical characterization;
  • Damage mechanics;
  • Thermal gravimetric analysis;

In this investigation, an automotive component made of nylon as a structural element was studied by several characterization techniques to identify material properties. Firstly, a Fourier transform infrared spectroscopy (FTIR) was carried out to obtain information about composition, then, differential scanning calorimetry (DSC) was used to extract useful information on sample thermal behavior. The humidity and volatile materials percentage could be assessed by thermogravimetry analysis (TGA). Morphology and topography were carried out by optical microscopy, moreover, X-ray Tomography allows it to display the sample’s inner part. Characterization shows that the component could have been contaminated or exposed to conditions that promote degradation after the manufacturing process. Finally, computerized X-ray tomography displayed that both samples showed a difference in porosity in a fractured sample and a healthy sample. All the above implies a change in the mechanical integrity of the fractured material but might not omit the fact that it could have been subjected to any type of impact or mechanical effort.

Although carbon fiber-reinforced polymer (CFRP) composites have excellent intrinsic mechanical properties, they are vulnerable to impact loads because of their weak inter-laminar fracture toughness, which results in delamination damage. This study presents a novel hybrid nanofiller combination of multi-walled carbon nanotubes (MWCNT) and alumina nanoparticles (Al2O3) to determine improvements in the impact resistance of CFRP laminate. The projectile impact experimental study is carried out on 140 mm × 140 mm × 1.5 mm CFRP laminate with spherical and conical nose shape projectiles. The numerical study of the test plate consisting of six layers is performed, in which each layer is modeled using a shell element and connected through tiebreak contact. Using the Cowper–Symonds equation to determine the dynamic mechanical properties, the numerical validation is established considering the strain rate effect. The results, such as residual velocity, damage area, ballistic limit velocity and delamination obtained from numerical analysis, are compared with the experimental observations. In laminates with hybrid nanofillers, residual velocity decreased by 20% and 9% when spherical and conical projectiles were impacted, respectively. The study indicates that 0.1 wt% MWCNT + 1 wt% Al2O3 nanofiller concentration embedded CFRP offers better resistance against spherical and conical projectile impact. Full article
