Energy consumption and CO2 emissions of joining processes for manufacturing hybrid structures

摘要: Abstract The industrial production must be driven forward by a leading idea, which aspires to prevent pollution and reduce the carbon emissions. A greener future is motivating technological progresses. key word sustainability protecting environment of low impact solutions. In manufacturing, this has been resulting in process optimization guarantee quality safety standards parts exhibiting an as possible environmental impact. introduction new materials their combination one strategies that pursued. context, joints between dissimilar are important affecting weight, mechanical properties costs manufactured structures. proposed research, primary joining categories (i.e. mechanical, thermal chemical processes) have analysed assessing consequences engineering hybrid Specifically, components polymer matrix composites (PMC) metals (lightweight alloys) These result weight saving without being forced performances or increase parts. Joining solutions can connect PMC lightweight alloys been, therefore, considered performed comparison. energy consumption CO2 emissions investigated processes, equal bearing strength for each them, shown better fastening bolts. Currently, only solution, allows part disassembling. However, recycling requirement dismantling developed. For reason, study extended taking down whatever solution. Hence, adhesive bonding ultrasonic spot welding become environmentally-friendly well.
