Resin Transfer Molding (RTM) is a manufacturing process that involves injection of liquid resin into a closed mold cavity containing preset fiber mats and a subsequent curing stage. Mold filling is a crucial stage for quality part productions. In order to automate production and minimize the formation of defects, control of mold filling is needed. In this paper, direct adaptive control strategy...

Abstract Carbon fibre reinforced plastic (CFRP) manufacturing cycle time is a major driver of production rate and cost for aerospace manufacturers. In vacuum assisted resin transfer molding (VARTM) where liquid thermoset infused into dry carbon reinforcement under pressure, the design distribution network to minimize fill while ensuring preform completely full critical achieving acceptable qual...

Sandwich composite structures have advantages of light weight, high strength, impact resistance, stability, other superior features advanced applications. In this regard, different core materials been in structures, such as cellular polymer foam, metallic honeycomb, balsa, tu...

Carpets are the three-dimensional product used as a floor covering in homes, offices, commercial centers, decorative purposes, etc. The average life span of carpet is four to seven years and after that, it becomes solid waste. discarded carpets causing significant hazardous effect on environment, climate, soil, various health issues. To overcome increasing waste, re-utilization essentially desi...

Resin Transfer Molding (RTM) is a composite manufacturing process. A preformed fiber is placed in a closed mold and a viscous resin is injected into the mold. In this paper, a model is developed to predict the flow pattern, extent of reaction and temperature change during filling and curing in a thin rectangular mold. A numerical simulation is presented to predict the free surface and its inter...
