| contents | Design and fabrication of a low speed Impact tester F. A. Godínez F. Serrania Margarita Navarrete Montesinos Ingeniería Sandwich panels Low impact behavior Composite structures The impact response of sandwich panels with an improved structure to increase their impact resistance isinvestigated. In order to compare the impact performance of sandwich structures, a specific and instrumenteddrop-weight impact tester was designed and developed. The experimental part of this work is an evaluation oncomposite sandwich panels behavior used in the manufacturing of the UNAM Electrobús chassis. Two differentsandwich structures are analyzed: the first type is a structure composed by a glass fiber-polyester matrix compositefacesheets and a polyethylene honeycomb core. The second one consists of facesheets made from a glass fiberepoxymatrix composite laminate and core formed by internal phenolic honeycomb structure. The first structurewas specifically designed to improve crashworthiness for transport applications. The main results of this study areevaluated from the absorbed energy performance of the sandwich structures subjected to a single impact, and thedevelopment of useful criteria for materials selection. 2004 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47402308 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.3 Vol.2 |
