“…Electrospinning is currently generally acknowledged as one of the most effective industrial nanofiber production technologies [13]. Fibre-reinforced composites are used in a variety of industries: e.g., medicine antibacterial characteristics [14,15], reinforced polymer composites [16][17][18], civil engineering construction [19][20][21][22]. Electro spun nanofibers offer a broad variety of applications due to their multiple advantages, including oil/water separation, air filtration, tissue engineering scaffolding, drug delivery [23], sensors [24], composites for load bearing [25][26][27] and advance structures [28,29].…”

Nanofibers have acquired greater interest due to their vast variety of possible uses. Nanofibers offer several options to change things physically and chemically during or after the manufacturing process to give them new properties. To exploit the full potential of nanofibers, it is necessary to comprehend the link between the mechanical characteristics, particularly tensile strength, of a nanofiber mat and its morphology. Electrospinning is a rapidly developing polymer processing technology because it provides a simple and effective method for manufacturing nano continuous fibres. This method permits the deposition of nanofibers on revolving collectors. Rotating collectors, such as the drum and electrodes with a gap between them, may readily form oriented fibres. Polyacrylonitrile is a common precursor material for carbon nanofibers (PAN). This research investigates the impact of collector drum’s rotation speed on the morphology of the nanofiber mat and discusses the mechanical properties of Polyacrylonitrile (PAN) electro spun nanofiber mats with precisely aligned nanofibers. PAN nanofiber mats have more tensile strength (~37 %) than PA6 nanofiber mats and have (50 %) less elongation than PA6 nanofiber mats, according to a comparison with previous studies.

“…If the process is new or little known, or does not have a mathematical model, experiments should be carried out. This approach is described in the works [8][9][10][11][12][13][14]. Focus on practical methods for solving real engineering optimization problems of specific optimization examples for induction heater modes and designs, particularly those used in industrial applications are investigated [6].…”

Induction heat treatment is an important tool in metallurgy. Induction annealing is a complex yet efficient manufacturing process with great potential for quality control of produced parts. Induction annealing is rarely used, but has its place and the control methods are similar to induction hardening. It allows much greater control over convection type heat treatment and allows more easily treating only selected regions on the material. One of the obstacles with heat treatment of brass parts is that it is not possible to get a direct reading with the infrared temperature sensor off the surface, therefore making the induction method heat treatment more practical than convection, as it offers almost direct control of the amount of energy inserted into material. We used induction to stress relief and anneal a hollow brass material cylinder to the desired hardness gradient. Four types of variables were controlled until the desired result was found. They are in shape of solenoid, location of solenoid in relation to the part, maximum power used and total induction time. Hardness was measured both on the outer surface of the parts and on parts cut in half. Hardness was measured using appropriate scale measurement systems using the Vickers scale. It was found that hardness differs on the surface measurement from the measurement on the inside, yet there seems to be a certain correlation on the differing amount. Induction offers a very quality controllable process with little difference in hardness form part to part. Empirical optimization is very time consuming and investing time in creating a mathematical model to do the bulk of optimization could be worth it.
