Study of process variables in resin transfer molding for polymer sandwich composites manufacturing

Polymer sandwich composites laminates are being increasingly used in various components in automotive, maritime and aerospace industry. These materials are used mainly due to their high strength and low weight. Resin Transfer Molding (RTM) is a versatile and efficient manufacturing technique for sandwich composites structures. The process consists of injecting a liquid thermosetting resin into [...]

Effect of process parameters on the characteristics of ductile cast irons.

Ductile cast irons are ferrous alloys in which there is a metallic matrix with graphite precipitation in the form of nodules. Their industrial use is focused on parts that require moderate ductility without reduction on mechanical strength, such as valves, automotive parts and hardware tools.  Its characteristics and therefore the quality are influenced by the [...]

Study of metal flow in a permanent mold with aluminum (culminated)

Numerical simulations provide a powerful means of analyzing various physical phenomena occurring during casting processes. It gives an insight into the details of fluid flow, heat transfer and solidification. Numerical solutions allow researchers to observe and quantify what is not usually visible or measurable during real casting processes. The goal of such simulations is to [...]

Development of cast iron with improved characteristics using computational methods for mold design. (in process)

The use of cast iron in Colombia (including steel) reached quantities of 13.661 tons in 2006 (ANDI, 2009).  Despite the widespread use of these materials, there is a lack of research and innovation in the area of iron foundries to keep the pace with international.  The existing ductile cast iron products in the national market [...]

Degradability determination of polymer blends: Thermoplastic starch/Low density Polyethylene and Thermoplastic starch/Polyhidroxybutyrate (PHB)

Biodegradable polymers have been developed as a way to substitute synthetic polymers and avoid their excessive use. However, the raw materials that offer biodegradability in a short term do not exhibit the best physical properties, while the synthetic biodegradable polymers present good properties with the setback of their high cost to be used massively. These [...]
