![]() ![]() The authors’ aim, in accordance to standards requirements, is to achieve a final design based on an optimized structural solution for the chosen process technologies taking into account the low volume production, typical attitude of the aeronautical industry. The study case is represented by a high performances aeronautic seat structure having as mission profiles the SAE-AS Standards, in order to demonstrate occupant protection when a seat/occupant/restraint system is subjected to statically applied ultimate loads and to dynamic impact test conditions. This paper describes a specific new approach which considers product/process guidelines an input/output data in the optimization phase. ![]() This aspect becomes a disadvantage in the Design revue phase when the final Product release is a trade-off between the Optimization results and the Manufacturing constraints. Optimization procedures, many times, do not include manufacturing constraints arising from the Corporate technologies. Structural Optimization techniques are a well-known approach in order to improve Product Performances. The outcomes of the study are used to provide recommendations on the short and long-term strategies to increase the eco-friendliness of the PET bottle industry. A life cycle assessment and a finite element analysis were carried out to evaluate the overall environmental impacts of the PET supply chain and the structural performance of PET bottles. The objective of this study is to present a methodological framework for comparing the environmental performance and structural performance of PET bottle designs, using case studies from the Sri Lankan market. To obtain a holistic vision of the actual impacts of this industry, life cycle thinking becomes necessary. The local PET bottle market has a range of products to cater the various customer requirements. Reducing the amount of material used, design for recycling, repurposing, and reusing are possible approaches for mitigating the negative environmental impacts of the PET bottle industry. However, the use of PET has a considerably detrimental effect on the environment, and many studies have been carried out on curbing this damage. PET bottle production has increased by over seven times within the last three decades. ![]() Polyethylene Terephthalate (PET) has become the most commonly used material in the global beverage bottling industry. ![]()
