Filler-content determination of wood-based composites by thermogravimetric analysis

Inorganic and Prepolymerized Filler Content Analysis of Four Resin Composites

Determination of Coal Rank by Thermogravimetric Analysis

INTRODUCTION The thermogravimetric analysis patterns of coals and their residues reveal subtle differences between coals and changes which occur during the processing. It is the purpose of this paper to call attention to some of the various processes occurring during the TG analysis, and to show how these patterns can be interpreted in terms of changes or differences in coal structure. It is al...

Correlation of filler content and elastic properties of resin-composites.

OBJECTIVES The aim was to determine the Young's modulus (E), bulk modulus (B), shear modulus (G) and Poisson's ratio (nu) of a series of composite restorative materials and to correlate them with their filler volume-fractions. METHODS Twelve model resin-composite formulations, with systematically varied volume-fraction (Tokuyama), a flowable resin-composite (Point 4 flowable, Kerr) and two hy...

Effects of monomer composition and original filler content on filler loading in the resulting centrifuged composites.

This study examined the effects of monomer composition, original filler content, and application of centrifugal force on the resulting filler loading of composites. Either Bis-MPEPP or UDMA was mixed with TEGDMA at a molar ratio of 1 : 1. Silane-treated silica (14-20 wt%) was added to each mixture. After the mixtures were centrifuged and light-polymerized, rate of increase was determined as the...

Eco-Friendly Natural Filler Based Epoxy Composites

In this study, acrylated soybean oil (AESO) was used as modifying agent for DGEBF-type epoxy resin (ER). AESO was used as a co-matrix in 50 wt % with ER. Composites with ecofriendly natural fillers-banana bark and seashell were prepared. MNA was used as a hardener. Effect of banana peel (BP) and seashell (SSh) fillers on mechanical properties, such as tensile strength, elongation at break, and ...
