The mechanical properties and quality of the RTM resin products depends highly on the complete filling and curing of resins in the mold. Hence, a method for monitoring the filling and curing of resins in mold has been a challenging problem in the field of RTM fabrication for a long time, particularly for thick components. In this paper, we describe a promising online method to monitor the flow ...

Accomplishments Analysis of the current modeling approach for CRTM, as well as for some of the physical phenomena involved in the process, such as preform deformation, revealed certain weaknesses in the numerical approach and, more importantly, significant gaps in fundamental understanding of underlying physics. New governing relations for the general Liquid Composite Molding (LCM) and, in part...

Resin transfer moulding (RTM) is commonly used for the production of high-performance fibre-reinforced polymer composites. In numerous application areas, the addition of fillers is necessary to enhance some properties of the polymer matrix or provide it with additional properties, such as flame retardancy. As many of the applied additives are solid phase, the reinforcement layers may filter the...

acrylic resin denture bases undergo dimensional changes during polymerization. injection molding techniques are reported to reduce these changes and thereby improve physical properties of denture bases. the aim of this study was to compare dimensional changes of specimens processed by conventional and injection-molding techniques.sr-ivocap triplex hot resin was used for conventional pressure-pa...
