“…The available works on this topic are few and limited to either the environmental footprint or the cost quantification of a product. In this context, several studies have performed either Life Cycle Analysis (LCA) of carbon fiber reinforced polymers, e.g., [1][2][3][4][5][6][7] or Life Cycle Costing (LCC) analysis, e.g., References [8][9][10][11] of carbon fiber reinforced polymers. An LCA study was conducted by Timmis et al [1] to quantify the environmental impact derived from the use of composite materials in an aircraft's fuselage used in place of other structural materials (e.g., aluminum alloys).…”

“…Furthermore, a number of studies are dedicated to the cost efficiency assessment of the composite materials, e.g., References [8][9][10][11]. In Reference [8], an overview of the extensive field of cost estimation for aerospace composite production, describing the basic methods of how to perform cost estimation and introducing some of the existing LCC models, is made.…”

Comparative Environmental and Cost Analysis of Alternative Production Scenarios Associated with a Helicopter’s Canopy

In the present work the carbon footprint and the financial viability of different materials, manufacturing scenarios, as well as recycling scenarios, associated with the production of aeronautical structural components are assessed. The materials considered were carbon fiber reinforced epoxy and carbon fiber reinforced PEEK (polyetheretherketone). The manufacturing techniques compared were the autoclave, resin transfer molding (RTM) and cold diaphragm forming (CDF). The recycling scenarios included mechanical recycling and pyrolysis. For this purpose, Life Cycle Analysis (LCA) and Life Cycle Costing (LCC) models were developed and implemented for the case of a helicopter’s canopy production. The results of the study pointed out that producing the canopy by using carbon fiber reinforced thermosetting composites and involving RTM as the manufacturing process is the optimal route both in terms of environmental and financial efficiency. The environmental and financial efficiency of the scenarios including thermoplastic composites as the material of choice is impaired from both the high embodied energy and raw material cost of PEEK. The scenarios investigated do not account for potential benefits arising from the recyclability and the improved reusability of thermoplastic matrices as compared to thermosetting ones. This underlines the need for a holistic aircraft structural optimization approach including not only performance and weight but also cost and environmental criteria.

Co-advisor: Dr. Manjusri Misra BioABS, which is a light-weight, recyclable green composite made from engineered soybean hulls, is a potential replacement for the petroleum-based plastic Acrylonitrile Butadiene Styrene (ABS). The purpose of this study is to assess the financial feasibility of BioABS relative to ABS.ABS and BioABS are substitute outputs sold for the same price and the production processes are essentially the same. Thus, the differences in net returns are based on differences in variable costs. ABS consists of 25% acrylonitrile, 20% butadiene, and 55% styrene, while BioABS is made up of 6.75% acrylonitrile, 5.4% butadiene, 14.85% styrene, 63% PLA, which is made from corn, sugar beets or rice, and 10% soybean hulls. The variable cost of producing BioABS is $1896.55/t, which is 4% higher than traditional ABS. If the price of styrene increases by 12.5% or if the price of PLA falls by 5.7%, BioABS then can be produced cheaper than ABS.iii ACKNOWLEDGEMENTS

“…Willden, 1997). Popular techniques include comparative techniques (Bader, 2002), process-orientated cost models (Gutowski, 1999;Choi, 2009;Kassapoglou, 1997), parametric cost models (Schubel, 2010;Ye et al , 2009) and process fl ow simulations (Barlow et al , 2002). These methods can provide a good guide to component cost, depending on your application and skill level.…”
