Processing of post-industrial unidirectional prepreg tapes using SMC equipment

نویسندگان

چکیده

The aerospace industry has an issue of disposing waste, unused carbon fiber unidirectional prepreg tapes. This paper explores producing chips using sheet-molding compounding equipment (SMC) for conversion into products via compression molding, which are stronger than traditional glass-reinforced SMC parts due to the and high strength epoxy resin. Without a means convert continuous tape chips, it will not be possible useful product provide way reduce flow landfill produce less expensive, lighter, transportation industry. cure state resin in tapes, is affected by amount time material spent stored at elevated or room temperatures, significantly changes ability chopped short chips. In addition, equipment-related factors affect material’s equipment. accounts each these uses statistical methods design experiments investigate impact material-related on success cutting portion process. level cure, as defined endothermic peak, glass-transition temperature (Tg), heat reaction/degree greatest For with moderate sharpness blades roller also major pressure, speed, tension have process, but lessens feedstock sufficiently cure. An optimal setup was determined, general rules thumb selecting settings were established.

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Post-processing of Direct Teaching Trajectory in Industrial Robots

Direct teaching of the industrial robot is a novel technique to easily teach manipulators. However, teaching data by human hand cannot help having large noise errors ranging from low to high frequency. To use teaching data, post-processing to correct the teaching trajectory is required. Here, a novel shape-based trajectory correction method to rebuild teaching data with the feature information ...
