“…Takasu [19] has demonstrated the friction spin welding machine for welding of thermoplastics in a horizontal orientation for joining pipes in butt joint configuration. The friction spin welding is generally performed in butt joint configuration and does not speak of shear joint configuration [20,21]. The schematic difference between butt joint and shear joint configuration for friction spin welding is shown in Fig.…”

The welding of thermoplastic pipes under a shear joint configuration using friction spin welding is investigated. The shear joint configuration consists of two cylindrical and concentric polypropylene plastic parts joined with each other at their interfacing cylindrical surfaces through frictional heat generation. The effects of welding pressure and rotational velocity on the joint overlap distance and joint strength between the parts of polypropylene plastic are evaluated. The study is of a specific application in making plastic pressure vessels and joining of pipes. The joint strength is tested by conducting the hydraulic pressure burst test. The burst test is conducted for welded specimens manufactured using different values of rotational velocity and welding pressure. It is observed that at the constant spin velocities, the welding pressure in the range 64.8 to 65.2 kPa produced better joint strength than the other values of welding pressure in the overall range 64–76 kPa. It is concluded that the suitable welding pressure range to manufacture polypropylene plastic pressure vessels in the shear joint configuration using friction spin welding is 64.5 to 65.2 kPa. Further, it is established that the user can control the joint overlap distance at 64.8 kPa welding pressure by selectively controlling the rotational velocity in the range of 700 to 2500 rpm.

“…The carried out experimental study was used to develop a numerical model for the analyzed fabrics. Such a model can be successfully employed to carry out different simulations necessary for the design process [14][15][16][17]. Based on the determined data from static tensile test, two materials were selected for modeling in the numerical analysis software.…”

The need to diversify the sources of raw materials used in industry has resulted in the increasing popularity of recycled materials. This situation is also observed in the clothing industry, which shows a growing interest in using recycled down and feathers from old jackets. Because the recovery process was being carried out manually, it is necessary to automate the process. Designing a suitable device requires testing to allow the modeling of the process to be carried out by the machine. The article presents the results of experimental tests whose purpose was to determine the material properties necessary to carry out numerical simulations of the destruction process of polyester fabrics. The article further presents the research methodology together with the research stand and discusses the results obtained.

The paper discusses the topic of butt welding of polyurethane drive belts by the hot plate method in the context of modeling the process of this technological operation. Based on the analysis of the butt welding process, a series of studies of the thermomechanical properties of the material from which the belt is made has been planned. The results will be used for mathematical modeling of the welding process, and in particular its most important phase: the plasticizing operation. On this basis, the study of the compression of cylindrical specimens taken from the belt has been performed at two different speeds. Their result is the relationship between the compressive stress σc and the modulus of longitudinal elasticity Ec at compression and: deformation εc, temperature value T, as well as the compressive velocity vc. In the next step, dynamic viscosity η of the belt material was determined based on the results of dynamic thermomechanical analysis. The research work culminated in the attempts to plasticize the material on a hot plate, in conditions similar to the process of industrial welding. These studies were performed at different speeds vpl, resulting in the correlation between the force required for plasticizing Fpl and the value of the speed of the belt end vpl relative to the hot plate heated to a temperature Tp. The obtained results will be used to formulate a mathematical model of plasticizing the material, based on the selected mechanical deformation models.
