The amount of alumina added in natural rubber foams were varied from 0 to 60 phr on 100 phr of natural rubber in a sulfur curing system. The sodium bicarbonate (NaHCO3) and N,N?-dinitrosopentamethylenetetramine (DNPT) were used as foaming agents. The sponge rubber composite foams were characterized for the microstructure, phase formation, thermal property, particle size distribution, and mechanical property by scanning electron microscope (SEM), X-ray diffraction (XRD), thermogravimetric analyzer (TGA), particle size analyzer, and compression set testing. The fabricated sponge rubber composite foams have distinctive characteristics such as light weight and good mechanical and thermal properties suitable for energy absorption such as thermal, noise, and vibration.

The use of particles in fibre-reinforced composite structures usually improves the strength of the basic material. Alumina (Al2O3), with its unique properties, has been used to improve the composite material's properties. It is crucial to determine the appropriate concentration of Al2O3 particles that can be added to Polypropylene whisker/epoxy composites to get the required mechanical and physical properties. In this study lamination 80:20 resin was used as a matrix material to prepare a Polypropylene whisker (3%wt.) reinforced lamination 80:20 resin (PP/resin) composite. The composite materials were manufactured by hand lay-up method. Different concentrations (1, 3, 5, 7 & 10wt.%) of alumina (Al2O3) particles, were used to reinforce the composite. The composite materials are prepared with standard sizes according to the tests, the tests include mechanical tests (tensile, impact, and hardness test) and physical tests (water absorption and density). The tests results showed an improvement in tensile strength, elongation, toughness, fracture toughness, hardness and density, while the water absorption diminishes concerning an increase in the concentration of the Al2O3 particles. The tensile strength, elongation, elastic modulus, hardness and density improved from (17 MPa, 1.3%, 1.13GPa, 70 Shore D and 0.93gm/cm3) respectively for neat lamina and reach the maximum value (34.5 MPa, 3.1%, 1.47 GPa, 83 Shore D and 1.01 gm/cm3) respectively at (3%wt. PP and 10%wt. Al2O3), while the toughness and fracture toughness improved from (3.8 KJ/m2 and 0.06 MPa.m1/2) respectively for neat lamina and reach the maximum value (23.1 KJ/m2 and 0.19 MPa.m1/2) respectively at (3%wt. PP and 7%wt. Al2O3). Note de contenu : - Materials and Methods

Tomographie à rayons XIndex. décimale : 667.9 Revêtements et enduits Résumé : Epoxy coatings are increasingly becoming popular choices as barriers against acids and alkali for protection of concrete and metal products. In applications, metal containers are often coated with epoxy-based coatings to prevent rusting and corrosion. In this study, an experimental examination was carried out to investigate the effect of particle shape and size on the friction and wear behavior of epoxy coatings. Friction and wear experiments were conducted using a pin-on-disk tribometer. Epoxy resin was filled with four different shapes of glass particles (spherical, flake, rod, and irregular shape) and varying particle sizes. Fillers were settled down and filler surface area fraction through thickness was characterized using microcomputed tomography (micro-CT). The wear mechanisms such as matrix wear, matrix cracking, particle fracture, particle debonding, and pullout and debris formation were studied using scanning electron microscopy. According to observations, it was found that particle shape has an effect on the wear characteristic. Particle fracture and particle pullout mainly dominated the wear in the samples of flake- and rod-shaped fillers, perpendicular matrix cracks occurred in the samples of spherical fillers, large debonding at the particle–matrix interface without particle pullout occurred in the samples of large irregular-shaped fillers (75–150 µm), and matrix cracks dominated the wear as the size of irregular-shaped fillers decreased to 50–75 µm. Further, it was found that friction coefficient depends on the shape of the particle. The samples with spherical- and irregular-shaped fillers had higher friction coefficient as compared to the samples with flake and rod fillers.

Revêtement -- SéchageIndex. décimale : 667.9 Revêtements et enduits Résumé : The role of pigment particle size distribution on stress and microstructure development was studied for coatings prepared from aqueous suspensions of ground calcium carbonate (GCC) and latex binder. Stress development was monitored using a modified beam deflection technique under controlled environment. Microstructure was characterized by scanning electron microscopy (SEM) and cryogenic SEM. For coatings containing only GCC particles and no latex, a wide particle size distribution resulted in a significant particle size gradient in the cross-sectional microstructure and irregular stress development. With latex addition, uniform microstructures were observed in coatings with either wide or narrow GCC particle size distribution. GCC/latex coatings prepared using GCC with a wide particle size distribution developed a higher stress than those prepared using GCC with a similar average particle size but a narrow particle size distribution. The higher stress is related to the particle packing that results in smaller pore sizes and larger capillary pressures that drive compaction. In coatings prepared with the same GCC particles but different latex binders, the stress and cracking behavior of the coating depends on the latex properties.

SéchageIndex. décimale : 667.9 Revêtements et enduits Résumé : Particle aggregates formed in a dispersing medium may be destroyed depending on the shear history applied in the coating process. Yielding behavior of gelled-clay particle dispersion can be interpreted as the destruction of particle network structure with the increase in shear strain. In the present study, gelled-clay particle dispersion was coated at different shear strain to control the initial status of particle aggregation of the drying process. The packing behavior of clay particles in the coated film was investigated from the viewpoint of void fraction in the film by the simultaneous measurements of weight loss and thickness decrease. Additionally, the change of surface roughness was researched based on the scattering pattern analysis. As a result, it was found that dispersed particles started to be packed tightly in the constant drying rate period, and that void fraction and surface structure of particle-packed layer scarcely changed in the latter part of the falling drying rate period. In contrast, if clay particle aggregates remained at the beginning of drying, a loosely packed particle layer was formed without changing surface structure in the constant drying rate period. However, the surface roughness was increased continuously in the falling drying rate period in spite of keeping constant film thickness, probably because void in the particle layer was collapsed.
