Thermoset-based composite materials exhibit distortions as a result of the manufacturing process. The shape of a composite part deviates slightly between the beginning and the end of the cure, owing to several irreversible phenomena. If these distortions are not anticipated, the assembling of several components together may require unacceptable for...

This article presents a new method for the production of disposable carbon fiber formworks for the casting of reinforced concrete columns. The desired three-dimensional object can be made by the robotic hot wire cutting of polystyrene, thus generating the shape around which the carbon fiber is deposited. The manufacturing technique is the so-called...
Blow and blow forming process for glass bottle is already validated for 2D axisymmetrical bottles. Current research evaluates the capabilities of the 3D simulations with more complex geometries. This article presents the results of a numerical and experimental study of a non-axisymmetrical glass bottle. In this study, a perfume bottle with a square...
In the present era, polystyrene foam is widely used in foundries for pattern making. Industries extensively use the steam molding routes for polystyrene foam pattern making. However, the molding method cannot produce complex geometries. Industries are using the machining route for pattern making to overcome these limitations. There is limited resea...
Zirconia-based ceramics have many applications in manufacturing, energy, and biomedical industries due to their excellent properties such as high thermal and oxidation resistance, excellent chemical stability and mechanical strength. Traditional manufacturing processes such as cold pressing, hot pressing, and injection molding have limitations in t...

Compression mold tooling fabrication has been traditionally conducted via machining processes—for example, computerized numerical control machining, mill, or lathe operations. While subtractive manufacturing operations provide high-precision tooling, they have an extended lead time and generate material waste, which increases manufacturing costs. T...

... Braids can be manufactured in a tubular or flat construction (see Figure 5). [28,29] Nonwovens fabrics Textile fabric structures made from fibrous webs are known as nonwovens. The web can be bound together in a variety of ways, including mechanical tangling of fibres, adhesive application, thermal fusion, and chemical structure development. ...
... Tolerances are often in the range of millimeters while typical part sizes are in the order of decimeters to meters [1], any unexpected deviations will create stresses in the zones where different parts are joined, hence weakening the overall structure. Understanding the mechanisms that lead to the development of residual stresses and how they may cause deformations is critical to designing a robust production process that is able to produce well-fitting parts [2] [3]. Doing this purely based on an empirical optimization routine would require an extensive experimental program, therefore making use of FEA in order to identify the parameters that are mainly responsible for geometric deviations is of great benefit to step up the design process with composite materials [4]. ...
... This portion of free strain is caused by the increase in density that occurs in most resins during curing. This leads to a total of about 5% shrinkage in most epoxies [3]. These free strains are developing all the way through the curing process but only become important once the material has gelled. ...
