The aim of this paper is to study the effect of silane treatment on woven banana fabric based unsaturated polyester resin composites. The fabric was treated with vinyl triethoxysilane. Woven banana fabric (WBF) reinforced unsaturated polyester resin (UPR) composites were fabricated by hand lay-up technique. The fabric content in the composite was kept constant to 35 %. The variation in the mech...

Macro-defect-free (MDF) cement with high flexure strength has been an active research area over several decades. To study the tensile properties of these materials, it is essential to understand the mode I crack propagation. In this article, cleavage cracking in calcium aluminate cement (CAC)–phenol resin composites is analyzed based on an energy method. The crack-trapping effect of the cement ...

An experimental polyethylene–candelilla-wax coating formulation was evaluated in comparison to a high-gloss, shellac and wood resin citrus coating for storage of ‘Valencia’ oranges at 15–25°C. Oranges with the wax coating had relatively high flavor scores (8.9–10.4) even after 9–16 days storage at 15–25°C. By contrast, the high-gloss coating, shown to be typical of such citrus coatings, resulte...

The objective of this study was to evaluate fluoride release amounts and patterns from high strength tooth filling material (EQUIATM) which is a conventional Glass Ionomer Cement, and investigate whether the application of nano-filled resin-based coating with different thicknesses has any effect on fluoride release from this new material. A total of 120 disc shaped specimens (10 x 2 mm) of EQUI...

OBJECTIVES The aim of the study was to develop a new kinetic model for the shrinkage-strain rates of dental resin composites. The effect of filler content on the shrinkage-strain kinetics and degree of conversion of dental composites was also investigated. METHODS A resin matrix containing 65 wt.% Bis-GMA and 35 wt.% TEGDMA was prepared. 0.5 wt.% camphorquinone and 0.5 wt.% dimethyl aminoethy...

STATEMENT OF THE PROBLEM Structural integrity and dimensional stability are the key factors that determine the clinical success and durability of luting cements in the oral cavity. Sorption and solubility of self-adhesive resin luting cements in food-simulating solutions has not been studied sufficiently. PURPOSE This study aimed to compare the sorption and solubility of 2 conventional and 2 ...
