Materials and Methods Materials The PCL used in this research work was Capa 6500 (Perstorp, UK), and the PLA was PLA 2002D (Cargill Down, USA).
The blends were prepared using 55g of each material.
In both cases, the films were cut in small pieces, and placed into desiccators to avoid material degradation.

Introduction The emergence of new materials, especially composite materials or multi-layer materials are increasingly used in industrial systems requires the knowledge of their thermophysical properties.
This method is based on the pulsed thermal imaging–multilayer analysis (PTI-MLA) method that has been commonly used for testing of coating materials.
In the case of our work, we consider a heterogeneous material consisting of several homogeneous materials of different thermophysical property. 2.
We assume that the thermal contacts between the different materials are perfect and that the contact resistances are null.

By optimizing fibre orientation, these structures can provide part-specific material properties that are superior to those of isotropic construction materials.
Additionally, composites offer design flexibility, allowing for the creation of complex geometries and curves that would be challenging or impossible with traditional materials.

Introduction Multiferroic materials exhibit simultaneous presence of (anti) ferroelectricity, (anti) ferromagnetism and ferroelasticity in the same phase.
Such kind of materials possesses tremendous potential for applications in multiple state memory elements, electric field controlled ferromagnetic resonance devices and transducers with magnetically modulated piezoelectricity [1].

In addition, our previous studies have found that ELID grinding produces a stable oxide layer on workpiece materials [3-5].
Chemical corrosive degradation and mechanical abrasion can act synergistically on these materials, and eventually lead to the deterioration of their functions.
