Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Erosion equations were developed to predict the material removal of polyurethane coatings on carbon fiber reinforced plastic (CFRP) surfaces and validated through experimental data. The effects of abrasive properties, process parameters, and organic coating properties (such as fracture toughness and hardness) were considered in the equations. As the erosion angle increased, elastoplastic deformation in the oblique direction and repeated "deformation" in the normal direction were the main reasons for material removal. The ductile erosion behavior was confirmed by experimental data because the maximum erosion rate occurred at an incident angle of 30°. The coefficient and index in the equations were determined by experimental data, and the equations were verified. The developed equations could accurately predict the quantity loss of organic coatings under different particle sizes and particle velocities, and the erosion equations were in good agreement with the experimental data.

Jute et constituantsLe jute est une plante herbacée de la famille des Malvacées, cultivée dans les régions tropicales pour ses fibres. Jute est aussi le nom donné à ces fibres textiles, appelées aussi chanvre de Calcutta.
Nom scientifique : Corchorus capsularis L., famille des Malvacées, sous-famille des Grewioideae ; la classification classique le situe dans la famille des Tiliacées. Une plante voisine, Corchorus olitorius L., la corète potagère, est aussi utilisée aux mêmes fins.

Tribologie (technologie)Index. décimale : 668.4 Plastiques, vinyles Résumé : Polymer based natural fiber reinforced composites are finding their applications in almost all fields of engineering. Flexible composites are different class of composite materials finding their usage in secondary structural application such as sacrificial structures like claddings. Mechanical and tribological characterization of the newly developed composites becomes important prior to using them in any engineering application. The present study concentrates on evaluating the tensile and slurry erosive behaviour of flexible composite manufactured by reinforcing naturally available jute fiber in the form of woven fabric in the naturally available sun dried rubber sheets (NR) using compression moulding technique. ASTM D412 standard is used to evaluate the tensile properties of the proposed flexible composite and the NR sheets. The slurry erosive behaviour is assessed using Ducom slurry erosion testing machine. The results reveal that reinforcing jute with natural rubber enhances the tensile strength compared to natural rubber sheet and the wear of the proposed flexible composite is minimal due to inclusion of natural rubber which is elastic in nature.
