Special Issue Information

Dear Colleagues,

Particle-reinforced composites are economical and easily fabricable options for high-strength materials. In general, hard ceramic particles are reinforced into different matrices (e.g., metals, polymers) to achieve higher strength and wear resistance. Particulate-reinforced composites find applications where a high level of wear resistance is required. The type, shape, and spatial arrangement of the reinforcing phase are the key parameters determining the mechanical behavior of the composite. The dispersed phase can be simply mixed with matrix powder or created by an internal reaction during fabrication. Particulate composites can be prepared by different manufacturing techniques such as casting, powder metallurgy, additive manufacturing, etc. In particulate composites, it is possible to achieve unusual combinations of properties. 

Particulate composites with a polymer matrix and solid fillers are an important type of material. Generally, these materials are used as construction materials, high-performance engineering materials, or protective organic coatings. Metal matrix composites with ceramic particle reinforcements find applications in cutting tools, and ceramic matrix composites finds applications in high-temperature environments. 

This Special Issue will address manufacturing, characterization, properties, and applications of advanced particulate composites to illustrate this material family.

Preparing a friction pair “polymer-metal” using improved polymeric composites is contemplated a complicated task due to the inert surface of the polymer. Gluing polymer composites with improved mechanical and tribological properties on metals and saving their unique properties at the same time is considered the best way to prepare slide bearing products based on polymer/metal. In this work, ultraviolet initiation is used after a process of mixed acid pre-treatment. The surface of highly oriented films based on ultra-high molecular weight polyethylene (UHMWPE)/graphene nanoplatelets (GNP) is grafted with nanocellulose. The grafting treatment is analyzed using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and contact angle measurements. Mechanical T-peel tests showed that the peel strength for the treated UHMWPE films increased by three times, up to 1.9 kg/cm, in comparison to the untreated films. The tensile strength of the treated UHMWPE films decreased by about 6% to 788 MPa. Tribological tests showed that the values of both friction coefficient and wear intensity of the treated UHMWPE films were increased insignificantly, which were 0.172 and 15.43 µm/m·m2, respectively. The prepared adhesive tape based on UHMWPE films, which can withstand a weight of up to 6 kg per 1 cm2 of the bonded surface, has a low coefficient of friction, high wear resistance, and high strength, and is considered a promising material for preparing slide bearing products.

Four piezoelectric ceramic materials with varying particle sizes and geometries are added up to 30 vol.% to a photopolymer resin to form UV-curable piezoelectric composites. Such composites solidify in a few minutes, can be used in UV-curing-based 3D printing processes, and can achieve improved sensor performance. The particle dispersion with ultrasonication shows the most homogeneous particle dispersion with ethanol, while two other solvents produced similar results. The viscosities of the prepared suspensions show some dependency on the particle size. The curing depth results show a strong dependency on the ceramic particle size, the difference in refractive index, and the particle size distribution, whereby composites filled with PZT produced the worst results and composites filled with KNN produced the highest curing depths. The SEM images show a homogeneous dispersion of ceramic particles. The highest dielectric properties are also shown by KNN-filled composites, while BTO and PZT produced mixed results of dielectric constants and dielectric losses. KNN-filled composites seem to be very promising for further 3D-printable, lead-free piezoelectric composite development. Full article
