- Article scientifique
Article scientifique
Abstract : "This paper deals with the numerical modelling of non-destructive testing of composite parts using active thermography. This method has emerged as a new approach for performing non-destructive testing (NDT) on continuous carbon fibre reinforced thermoplastic polymer (CCFRTP) components, particularly in view of detecting porosity or delamination. In this context, our numerical model has ...
Additively Manufactured Multifunctional Composite Parts with the Help of Coextrusion Continuous Carbon Fiber: Study of Feasibility to Print Self-Sensing without Doped Raw Material

Article scientifique
Abstract ; "Nowadays, the additive manufacturing of multifunctional materials is booming. The fused deposition modeling (FDM) process is widely used thanks to the ease with which multimaterial parts can be printed. The main limitation of this process is the mechanical properties of the parts obtained. New continuous-fiber FDM printers significantly improve mechanical properties. Another limitation ...
Impact of Green Ceramic Hybrid Machining (GCHM) on Reliability and Repeatability of the Properties of Sintered Yttrium-Tetragonal Zirconia Polycrystal Parts

Article scientifique
Abstract : "The innovative Green Ceramic Hybrid Machining (GCHM) process sequentially combines
milling with a cutting tool (GCM, Green Ceramic Machining) and laser beam machining (GCLBM) of
a ceramic material (black Y-TZP in this study) at the green stage mainly to increase productivity, avoid
taper angle limitations of laser beam machining, and obtain micro-features. The study focuses on ...

Acte de conférence ou de colloque
" This article aims to make a review of the existing benchmark artifacts and to summarize the main requirements chosen by authors. From this state of the art, a new benchmark artifact is proposed by adapting an existing one to fulfil its missing characteristics. Measurements possibilities in terms of dimensions are enumerated and organized using ISO 286 dimensional intervals as presented in the ...
Green Ceramic Machining: Influence of the Cutting Speed and the Binder Percentage on the Y-TZP Behavior

- Article scientifique
Article scientifique
Abstract : "The demand for inert bioceramics is always increasing in the dental field. Yttrium oxide tetragonal zirconia polycrystals (Y-TZP) are oxide ceramics which are currently used because of their interesting mechanical properties due to a toughening transformation. Industrially speaking, machining of the ceramic before sintering (green body) is very common because it allows a better productivity ...
Green Ceramic Machining: Determination of the Recommended Feed Rate for Y-TZP Milling

,
- Article scientifique
Article scientifique
Abstract : "Manufacturing of advanced ceramic parts exhibiting complex geometries is laborious and expensive. Traditionally, the machining is carried out on a so-called ‘green ceramic’: a compact composed of ceramic powder held with the help of a binder. This difficulty is due not only to the composition of the material, but also to the lack of methods that determine optimal machining parameters. ...

Contribution to ESAFORM2021.
Abstract :
"When modelling a cutting operation, the constitutive model of the machined material is one of the key parameters to obtain accurate and realistic results. Up to now, the Johnson-Cook model is still the most used, even if an increasing number of models, such as the Hyperbolic TANgent (TANH) model, were introduced last years to overcome its limitations and ...

Contribution to euspen’s 20th International Conference & Exhibition (Geneva, CH, June 2020)
Abstract :
"The ceramic microcomponents have very interesting mechanical and thermal properties in an extreme environment such as a high temperature, a corrosive environment, etc. Unfortunately, the principal limitation of ceramic material usage is its shaping because of the brittlness of the material. ...
