Dynamic Mechanical and Thermal Behavior Analysis of Composites Based on ...

Thermal properties, as well as the dynamic mechanical behavior of recycled polypropylene composites with vegetal leaves contents, were studied by thermal analysis techniques: TG/DTG, DTA, and DMA. Composites made of polypropylene recycled with 1%, 5%, 10%, and 15% ww?1 vegetal leaves were prepared using the melt blending technique. The results revealed that the viscoelastic properties were ...

Subsurface residual stress and damaged layer in highspeed grinding ...

The high energy consumption in grinding may result in a high temperature, causing thermal damage to the workpiece. When the temperature rises too quickly, many types of thermal damage occur. Thermal damage and heat distortion make it harder to maintain workpiece fatigue behavior and dimensional accuracy [9].

Mica is a plate like crystalline aluminosilicate and has been widely used as reinforcing filler in polymeric matrices due to its excellent mechanical electrical and thermal properties (10). The commercial delamination of mica may be characterized as wet or dry according to whether the delamination is carried out in a dry state as water.

Mechanical and thermal behaviours of grinding acoustic emission

This paper presents an investigation of the AE features in terms of grinding mechanical and thermal behaviour. A series tests of single grit scratching, tension testing and laser irradiation were carried out to simulate grinding process in order to separate the mechanical and thermal characteristics of grinding acoustic emission.

Thermal Aspects of Grinding: The Case of Upgrinding

Conventional grinding is usually carried out in upgrinding mode, with the wheel moving in the opposite direction from the workpiece. In this paper, a thermal model is developed for upgrinding. This model is similar to our previous models of downgrinding in that the behavior of the workpiece, grains, fluid, and chips are all coupled.

Smallgrit grinding did not induce a phase transformation but improved the flexural strength and ageing resistance. Glazing prevented zirconia from thermal ageing but severely diminished the flexural strength. The nanohardness and nanomodulus of the surface layer were increased by ultrafine grinding.

1. Introduction. Friction, as a phenomenon of an irreversible energy dissipation process, is intrinsically linked to an increase in entropy, which is a measure of disorder, leading initially to structural destruction in microareas of materials and subsequently to mechanical destruction [].Friction leads to wear and is, therefore, a process of destroying and removing material from the surface ...

Functional silicalignin dual fillers were obtained via mechanical grinding of the components (Syloid 244 silica and kraft lignin). Of particular importance here is the fact that lignin is a natural polymer and particularly that it is a waste byproduct of paper production, whose recycling is highly desirable. The product underwent comprehensive dispersivemorphological and thermal analysis.
