“…Some of these issues are significant mass losses, vibrations, noise, frequent maintenance/repair needs and surface erosion. 21,22 Polymer-based materials offer a few advantages over metals, such as: low density, low weight, less impact of pressure caused by shockwave, flexibility and so on. 21 This study presents the use of waste CR-39 as a reinforcement in the UPR resin, produced by catalytic depolymerization of waste PET.…”

Prior to achieving a homogenous dispersion of CR-39 particles in the UPR matrix, the filler was oxidized using acid/base treatment and activated with ethanol amine.…”

Two types of polymer waste materials, poly(ethylene terephthalate) (PET) and polycarbonate based Colombian Resin (CR-39), were used for the designing of fully recycled composite materials. Waste PET was employed for the synthesis of thermoset unsaturated polyester resin (UPR), while CR-39 was used as reinforcement in the UPR matrix. Prior to mixing, CR-39 particles were subjected to oxidation and chemical activation using acids/base and ethanol amine, respectively. The effect of the modifier type and variable loading of the activated CR-39 particles on mechanical and dynamic-mechanical properties of the corresponding composites was investigated. The greatest improvement in the tensile and flexural strength of UPR resin was achieved with the composite containing 0.5 wt% of amine activated filler particles, 96.0% and 62.2%, respectively. The Arrhenius equation was used to calculate the activation energy for glass transition from dynamic mechanical properties measured at various frequencies. The activation energy of the main transition for UPR resin and composites were calculated to be 173 and 350 kJ·mol−1 indicating that reinforcement results in an increase in the energy barrier to macromolecules viscoelastic relaxation. In addition, erosion resistance was studied during exposure of samples to cavitation tests. According to the obtained results, these materials can be applied in construction and mining industry.

“…Furthermore, polymer-based materials CE resistance is compared with the resistance of metallic structures. In the Taillon et al work [25] the fibre reinforced composite material (polyallylate fibre, commercially registered as "Vectran", chemically it is an aromatic polyester) was investigated using a cavitating jet apparatus inspired by the ASTM G134 standard. It is reported that the erosion rate of Vectran is close to that of aluminium alloy (A7075), but compared with SUS304 stainless steel and aluminium bronze, the erosion rate of the composite material is significantly higher.…”

Polyester coatings are among the most commonly used types of powder paints and present a wide range of applications. Apart from its decorative values, polyester coating successfully prevents the substrate from environmental deterioration. This work investigates the cavitation erosion (CE) resistance of three commercial polyester coatings electrostatic spray onto AW-6060 aluminium alloy substrate. Effect of coatings repainting (single-and double-layer deposits) and effect of surface finish (matt, silk gloss and structural) on resistance to cavitation were comparatively studied. The following research methods were used: CE testing using ASTM G32 procedure, 3D profilometry evaluation, light optical microscopy, scanning electron microscopy (SEM), optical profilometry and FTIR spectroscopy. Electrostatic spray coatings present higher CE resistance than aluminium alloy. The matt finish double-layer (M2) and single-layer silk gloss finish (S1) are the most resistant to CE. The structural paint showed the lowest resistance to cavitation wear which derives from the rougher surface finish. The CE mechanism of polyester coatings relies on the material brittle-ductile behaviour, cracks formation, lateral net-cracking growth and removal of chunk coating material and craters' growth. Repainting does not harm the properties of the coatings. Therefore, it can be utilised to regenerate or smother the polyester coating finish along with improvement of their CE resistance.
