Carbon Fiber Reinforced Polymer (CFRP) is Repair of reinforced concrete structures and both are used for reinforcement One of the composite materials. Polymer reinforced with carbon fibres an advanced non-metal made of resin compound, which is of high strength, Weight loss, itching and excessive fatigue It has many excellent performances like resistance. Carbon fiber reinforced polymer (CFRP) is the best specific machine has properties, so these products High such as automobile and aerospace sectors widely used in technical industries. Dimensional or assembly related requirements CFRP composites to complement Machining is often necessary. The approach is based on the Fuzzy TOPSIS technique (Fuzzy Technique for Order Preference by Similarity to Ideal Solution) this analysis using the Alternative Value Conventional twist drill, Double point angle twist drill, Brad & spur drill, Dagger drill, Core drill and Cutting force, Cutting torque, Tool wear, Cutting temperature is Evaluation parameters value Core drill is got the first rank whereas is the Dagger drill is having the lowest rank.

Hybrid composites are materials made of two or more different types of fibers incorporated into a single polymer matrix the year 2019 publication failure analysis in bio composites, fiber-reinforced composites, and hybrid composites. A hybrid composition of basalt and glass layer fabricated and its various mechanical properties after being tested. Glass-fiber composite is a magnificence of fiber-reinforced polymer composites. Hybrid compounds are common ones two or more in the matrix combining different types of fiber products manufactured by various hybrid gave researchers compounds have many definitions. A laser machine is a target material that interacts with a laser beam it is a material removal process done by such a device that uses photon energy processing to the target object thermal or photochemical energy is carried in the form of removing the items directly and by melting evaporation elimination. Commercial, industrial, aeronautical, maritime, and recreational constructions can utilize hybrid composites for their main structural components. It offers a wide range of advantages in the aerospace sector, including strong impact resistance, outstanding fatigue and corrosion resistance, and both. A hybrid composite made of layers of basalt and glass has been created, and after that, its varied mechanical characteristics have been examined. It takes time to precisely machine these composite materials. The mechanical performance of the hybrid composite is decreased by a number of constraints in traditional machining, including fiber pullout, delamination, burr formation, matrix crack development, etc. These issues might result in a poorly machined surface. The decision-making trial and evaluation laboratory (DEMATEL) is regarded as an efficient technique for locating the causal links in a complex system. It focuses on assessing the interdependencies between elements and identifying the crucial ones using a visual structural model. Lamp current (amp), Pulse frequency (Hz), Cutting speed (mm/min), Pulse width (ms), Air pressure (bars). From the result, it is seen that Lamp current got the first rank whereas the Pulse width is having the lowest rank.
