“…A composite material is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components [1][2][3][4][5]. The individual components remain separate and distinct within the finished structure.…”

The ultimate purpose of the project is to manufacture a composite shaft using a lathe machine (conventional method). For this process, we have designed a special lathe attachment over which our fiber will be worn. We use an E-glass fiber and the solution is an epoxy resin mixed with hardener.Initially, the fiber is taken to the required amount and weighed. The equitant amount of epoxy resin is weighed. Then 10% of the weight of hardener to epoxy resin is mixed. The lathe attachment consists of a resin bath in which the resin is poured. The fiber is made to dip into the resin bath so that the fiber is completely covered with resin. On the other end of the attachment, the fiber with resin is taken out and rolled over the mandrel ( stainless steel rod of required dimension ).The mandrel is initially wound with butter paper and coated with wax ( For easy removal). As the fiber rolled over the mandrel with engaging the tool post with the lead screw. The required gear attachment for the lead screw speed is set. The Lathe is rotated at the least speed. The required number of windings on the mandrel is given by moving it back and forth. Them the mandrel is removed from the chuck and made to dry. After this process, the mandrel is removed by taking out the butter paper. We get a hollow shaft that is made of compound material i.e.fiber and epoxy resin. The product is of improved strength and is used for the replacement of propeller shafts. This is a conventional way of fabricating a composite shaft with the help of a lathe machine. The design of part of it is the special lathe attachment.

“…Since a composite material that could be less cost and reduced weight is capable of replacing the conventional materials, it has to be tested in terms of various strengths based on their replacing application and material. Likewise, lots of research works are being conducted in the composite world [8][9][10][11][12]. Machining of composite by conventional methods may lead to delamination of the composites which in turn will not provide the necessary dimensional aspect.…”

Composite materials play an important role in many industrial applications. Researchers around the world are working to create new composites to improve the usefulness of these materials. GRP (Fiberglass Reinforced Polymer) is a composite material made from a fiberglass reinforced polymer matrix. They have better stiffness, strength, electrical conductivity, low coefficient of thermal expansion, excellent fatigue resistance, and the ability to produce materials of complex shapes. I am. In this study, different layers of different types of fiberglass cloth are used to manually manufacture fiberglass reinforced polymer hollow cylinder components and test the torsional and compressive strength of the sample. There are various fiberglass fabrics such as veil mats and textiles. Analysis is performed on the different types of samples generated to see if they are suitable for different applications. The results of the study show the effect of different layers of fiberglass on their strength and the possibility of replacing the weakly transmitting metal shaft with a composite shaft (GRP).

“…An experiment was conducted on carbon fibre reinforced polymer (CFRP) 26 and borosilicate glass to find out the effect of SOD, pressure and grain size on MRR and TA using AJM. 27,28 A comparative model 29 was established to investigate the effect of water jet and abrasive jet on the texture of machining area of coal. The effect of simulated input parameters had been investigated by using analysis of variance (ANOVA), grey relational analysis (GRA) in order to evaluate the displacement of cut, kerf width (both top and bottom), surface roughness and machinability using machining parameters i.e., jet pressure, traverse speed, feed rate, SOD on titanium alloys i.e., Ti6AL4V and other brittle materials using garnet abrasive in the abrasive water jet machining (AWJM).…”

K-80 alumina ceramic makes it challenging to machine them economically due to extreme hardness. Fluidized bed-hot abrasive jet machining (FB-HAJMing), in which a target profile is eroded by the impingement action of air-hot abrasive jet, which containing fine hot abrasive grains for machining of K-80 alumina ceramic materials without thermal damage. This study is intended to analyse kerf angle (KA), surface roughness (Rz) and material removal rate (MRR) using HAJMing process of K-80 alumina ceramic. Fifteen sets of experimental trials were conducted two times using tungsten carbide (WC) nozzle with and without internal thread. The identified three cutting parameters i.e., air pressure (P), abrasive temperature (T) and stand-off-distance (SOD), were considered for experimental design. Furthermore, the response surface methodology (RSM), statistical techniques (here, desirability function approach) followed by computational approach (here, genetic algorithm) are respectively employed for experimental investigation, predictive modelling and multi-objective optimization. Subsequently, confirmation tests evaluate the efficiency of the suggested two multi---objective optimization methods to rationalize the utility and awareness of the usefulness of hot abrasives in HAJMing. Moreover, computational fluid dynamics (CFD) modelling was utilized to develop a comprehensive relation between HAJMed profile geometry and erosive flow. Finally, the environmental ‘Pugh Matrix’ approach is proposed for the HAJMing process sustainability evaluation. The results indicated a desire to improve the cutting efficiency for material erosion by using hot abrasives in the HAJMing procedure. The most important parameter for surface roughness is abrasive temperature, while pressure is important for both KA and MRR. The use of hot abrasives in the FB-HAJM process has demonstrated a focus on improving the cutting performance for material removal. From an economic standpoint, the current study presents a technological criterion for feasible industrial applications of the FB-HAJM method, such as in aerospace, precision manufacturing, and biomedical field.
