The Wear of Acrylic Resin and Composite Resin Teeth against Polished and Glazed Zirconia
… available denture teeth made of different resins. Material and Method: Eight groups (n=10) of denture teeth and one control group (natural teeth) were selected. Two sets of each group were prepared along with two groups of natural molars as control groups (n=10). Two sets of 90 antagonist …

Critical thickness in silicone resin
… determined for the Dow Corning 4-3136 silicone resin. 4-3136 is macroscopically brittle, but becomes up to ten times more ductile when it is processed in the form of a sufficiently thin film. Thickness was controlled for the thin films of amorphous polymer through solution composition variation. …

Production of phenol-formaldehyde resin composites
… laminates based on phenol-formaldehyde resins, with a view of suggesting ways of improving the process economics and/or the physical properties of the final product. Aspects of impregnation, drying, and lamination were investigated. The resins used in all experiments were …

Tissue-equivalent and nanoparticle doped resin dosimeters
… characterisation and analysis of a new resin dosimeter (RD). This involved the creation of a new, simplified, formula containing resin precursors and a radiochromic dye (leucomalaquite green). The introduction of nanoparticles into the fabrication process was also explored. The spatial …

A Gasless Method of Spraying Thermoplastic Resin
<p>This spraying method for thermoplastic resins is a new manufacturing process for applying thermoplastics to a mold or surface in an efficient way that has the potential of reducing cycle time. Spraying thermoplastic resins is similar to spraying other polymers, such as paint, with the …

Mechanical properties of degraded PMR-15 resin
… a non-uniform degradation state in PMR-15 resin. A surface layer, usually attributed to oxidative degradation, forms. This surface layer has different properties from the inner material. A set of material tests was designed to separate the properties of the oxidized surface layer from the …

Evaluation of Phenol Formaldehyde Resin Cure Rate
… and costs. The research will further examine resin cure through dielectric analysis; such a technique could monitor resin cure directly and in real-time press situations. Hot-pressing processes could conceivably no longer require a set press schedule; instead they would be individually set …

Wood/Polymeric Isocyanate Resin Interactions: Species dependence
… of polymeric diphenylmethane diisocyanate (PMDI) resin is known to be highly dependent on the wood species. This species dependence may be due to differences in: cure chemistry, interphase morphology, or both of these factors. This study addresses aspects of the cure chemistry and interphase …

Development and verification of a resin film infusion/resin transfer molding simulation model for fabrication of advanced textile composites
… computer model for the simulation of the resin transfer molding/resin film infusion processing of advanced composite materials. This computer simulation model is designed to provide aircraft structure and tool designers with a method of predicting the infiltration and curing behavior of a …

Fiber Reinforcement Compaction In Resin Injection Pultrusion Process
Resin injection pultrusion is a cost-effective continuous manufacturing process to produce composites of constant cross-section. In this process, fiber reinforcements are continuously pulled through the injection chamber where liquid resin is injected to cause complete wetout of the fibers before …

In-situ cure monitoring of epoxy resin systems
… of monitoring the cure state of an epoxy/amine resin system. The sensors were of simple construction, consisting of an optical fibre from which the silicone cladding layer had been removed over a short length. This stripped length was embedded into the curing resin system. The sensor was …

Wetting and Penetration Behavior of Resin/Wood Interfaces
… the fundamental understanding of the wood-resin interaction, by looking at the relationship between the resin wetting onto wood and the resulting penetration into wood lumens. Wetting was analyzed with the sessile drop method, which observed the initial contact angle and change in contact …

In-Situ Measurement of Resin Shrinkage for Aerospace Components
<p>Resin shrinkage due to chemical changes and thermal gradients plays an important role in the residual stress evolution during composite manufacturing. In this thesis, we develop a new in-situ experimental approach for measuring resin shrinkage during curing with the help of digital image …
