Abstract
The bonding of metallic alloys and composite materials in the form of a hybrid structure is a line of great interest for the current industry. The different machinability of both materials requires a specific machining process. Abrasive water-jet machining (AWJM) is an excellent technology for the simultaneous machining of both materials. However, defects at the micro and macro-geometric level have been detected in several scientific articles. In this review, a detailed study of the two main defects in metals, composite materials and hybrid structures has been developed. The conclusions of several scientific articles have been exposed for a better understanding of the topic in articles between 1984 and 2020. The influence of the cutting parameters on the reduction in kinetic energy of the water jet and the order of stacking of the materials in the hybrid structure is the main objective in order to minimize these defects. Cutting parameter optimization studies, predictive model proposals, process-associated defects and evaluation methodologies have been discussed. The aim of this article is to set a solid background on AWJM machining in hybrid structures and on the influence of cutting parameters on generated defects and machining strategies to obtain the best results at a macro and micro-geometric level.
Highlights
The search for materials that improve the existing performance is constantly evolving in various sectors
Murugabaaji et al [62] carried out an experimental investigation on abrasive water-jet machining on a 40 mm thick stainless steel through a response surface methodology, studying the influence of hydraulic pressure, traverse speed and abrasive grain size on surface quality through ANOVA statistical analysis
This study develops a predictive mathematical model of second order that relates the surface quality with the traverse speed and the jet-piece distance, with an adjustment of 99.93%, marking as ideal parameters in terms of Ra a traverse speed close to 85 mm/min with a jet-piece distance of 3 mm, which are in accordance with those previously obtained by Pon et al for the water-jet machining of a carbon steel
Summary
The search for materials that improve the existing performance is constantly evolving in various sectors. One way to take advantage of materials with different nature is the formation of a hybrid structures (Figure 1) These structures are obtained by joining metal and composite sheets. FML (Fiber Metal Laminate): Overlay of low thickness sheets of metal alloys and unidirectional composite material stacked alternately. The union of both can be by mechanical or adhesive bonding. Hybrid Structure: This is the nomenclature that has begun to be used in the last few years and that will be adopted throughout this research work It refers to the union of a metallic alloy to a polymeric matrix composite material, which can be joined by means of an adhesive or thermal bond [19]
