Filling Time Reduction in Liquid Composite Molding Processes

نویسندگان

چکیده

The quality of Liquid Composite Molding (LCM) manufactured components is strictly related to the fibrous preform impregnation. As Darcy’s law suggests, resin flow influenced by pressure gradient, geometrical features reinforcement, and viscosity. former two parameters are dictated requirements component other constraints; therefore, they hardly modifiable during process. Resin preheating increases its fluency, thus enhancing impregnation saturation flow, reducing mold filling time. In present work, a microwave heating system has been integrated within vacuum bag infusion process, analyze effect online on fiber To monitor dielectric sensors-based used. Results from tests conducted with without pre-heating were compared: outcomes indicated an advance approximately 190 s front when applied respect unheated tests.

Coupled Flow-thermal Scalable Process Modeling Simulations in Liquid Composite Molding of Composite Structures

Net-shape liquid composite molding (LCM) processes for the manufacturing of composite structures involve the permeation of a reactive thermoset polymeric resin through complex, fiber woven preforms. The physical behavior during the processing thus involves coupled multi-physics phenomena consisting of mass, thermal and species transport. The flow process models based on conservation of mass are...

Review: Resin Composite Filling

The leading cause of oral pain and tooth loss is from caries and their treatment include restoration using amalgam, resin, porcelain and gold, endodontic therapy and extraction. Resin composite restorations have grown popular over the last half a century because it can take shades more similar to enamel. Here, we discuss the history and use of resin, comparison between amalgam and resin, clinic...
