“…The canopy is assumed to be made of a carbon fiber reinforced epoxy composite material, with a 60% fiber volume fraction. The total mass of the canopy was calculated based on [3] and found equal to 0,64 kg. As a result the mass of the carbon fibers and the epoxy were found equal to 0,384 kg and 0,256 kg respectively.…”

“…The results demonstrated that the environmental benefits occurred from mechanical recycling are impaired from the severe deterioration of the mechanical properties of the fibers leading to a low market value product. In parallel, efforts have been undertaken in optimizing structural components with regard to their quality and cost [3], [4], [5]. In [3] the manufacturing of a helicopter's canopy produced using the cold diaphragm forming technique is optimized from a financial and qualitative standpoint.…”

Abstract. In the present work, Life Cycle analysis (LCA) and Life cycle costing (LCC) models were developed in order to quantify the environmental footprint and cost and thus compare different manufacturing scenarios associated with the production of aeronautical structural components. To validate the models developed, they were implemented for the case of a helicopter's canopy processed by two techniques commonly used in aeronautics, namely the autoclave and the Resin Transfer moulding (RTM). The canopy was assumed to be made of a carbon fiber reinforced thermosetting material. Using the models developed the expected environmental and cost benefits by involving the RTM technique have been quantified.

Continuous fiber‐reinforced thermoplastics (CFTs) present some key advantages over thermosetting matrix composites, being characterized by recyclability, indefinite shelf life, and a significant potential for high volume production, associated with low costs. Short and long fiber‐reinforced thermoplastics obtained mainly using commodity polymer as matrices are already widely used in low technology applications. CFT applications are still limited, although in some cases notably for their technological value. This arises either from very high raw material costs or from not fully assessed processing routes. This review essentially focuses on the cost issues associated with the production of CFT parts in comparison with thermosetting matrix composites characterized by similar properties. Some cost models are reviewed, and the relationship between performances and costs is highlighted as a key feature for the choice of CFT. Their use in substitution of thermosetting matrix composites and metals is strictly related to raw materials cost, manufacturability at cost‐effective conditions, and availability of design data and test methodologies. CFT, characterized by shorter processing time than those required for thermosetting matrix composites, already offers promising solutions in many applications.

Possible use of volcanic ash as a filler in polyphenylene sulfide composites: Thermal, mechanical, and erosive wear properties

et al. 2014

It is a common practice to use particle materials as fillers to improve engineering properties of polymer composites and to lower the cost of final products. There is an obvious cost advantage of compounding volcanic ash (VA) in polymers, either to replace traditional fillers. This study is concerned with thermal, mechanical, and erosive properties of VA‐filled polyphenylene sulfide (PPS) composites. Composite samples containing VA particles at various concentrations (0, 2.5, 5, 10, 15, and 20 wt%) were manufactured by twin screw extruder and injection molding machine. Thermal properties were investigated by thermogravimetric and dynamic mechanical analysis methods. Erosive wear properties were investigated by performing solid particle erosion tests at 30º and 90º impingement angles. The mechanical properties such as flexural strength and modulus of uneroded samples and residual flexural strength and modulus of eroded composite samples were determined by three‐point bending tests. Results show that thermal, mechanical, and residual mechanical properties of the PPS composite were significantly improved by adding VA, although erosion resistance was decreased markedly. It was concluded that VA can be used as a reinforcement in PPS composites to improve thermal and mechanical properties and to reduce the cost of the PPS composites. POLYM.
