The fiber industry develops materials with good physical and mechanical characteristics, but it also generates a lot of waste that is difficult to degrade. Glass fibers can be extracted from waste glass fiber reinforced polymers because of advancements in grinding and sorting technologies. The objective of the current paper is to use waste glass fiber along with new woven glass fiber mat in structural application. Composites were manufactured using the hand layup method using virgin and discorded woven glass fibermats with different fiber weight fractions such as 10%, 20%, 30%, and 40%. Composites were then investigated for the influence of the recycled fiber on mechanical and vibration behavior using appropriate tests. Theoretical models were used to predict the mechanical behavior of the composites. Scanning electron microscopic technique was used to analyze the failure surface morphology of the composite specimen. Results portrayed that the composites with 40 wt% of new woven glass fiber mats exhibited better mechanical strength (tensile and flexural strengths and modules of 243 MPa, 1752 MPa, and 1244 MPa, 946 MPa, impact strength of 12.13 J). The combined effect of new and recycled glass fiber composites exhibited tensile and flexural strength of 211 MPa and 1734 MPa, modulus of 1222 MPa and 925.7 MPa, impact strength of 10.43 J. The natural frequency of both composites was very close to all other volume fractions. The theoretical model also ended up with the same result and the margin of difference between predicted results and experimental results was very minimum.

“…The samples used in this investigation were prepared using wet-lay-up technique and the concept of fiber orientation in the composite was equally adopted in this work in order to study the influence of the orientation of glass fiber on the tensile strength of the composite materials [23,24]. The wet lay-up forming method is the most suitable when it is about forming particular fabric reinforced polymer composites, especially when the pot-time of the polymer is long enough to ensure a good penetration of the pre-polymer in-between the fiber threads.…”

Fiber reinforced polymer (FRP) composites possess excellent specific strength, specific stiffness and controlled anisotropy for which these are extensively used in various engineering applications, like automobile industries, aerospace industries, marine industries, space industries, electronics industries and many more. Glass fibers (GF), carbon fibers (CF) and aramid fibers (AF) are common reinforcements for polymer matrix composites (PMCs). High mechanical properties and wear resistance behaviour of glass fiber reinforced composites are the premises for the current experimental research on the effect of fiber orientation on the tensile strength of the polymeric composite materials. The glass fiber reinforced epoxy resin composite was prepared by wet lay-up method, followed by thermal treatment.

“…But, these approaches have few drawbacks in terms of low MRR in dry EDM, high concentrated volatile mixture, chances of explosion in near dry EDM, oxide formation and corrosion effects in water based dielectric. In this decade, recently, vegetable oil is used as dielectric fluid by researchers in EDM process and it is observed for obtaining of sustainability in EDM process [1][2][3][4][5][6][7][8][9][10][11][12].…”

Wireless technology was one of the main areas of research in the world of communication system today and a study of communication incomplete without an understanding of the operation and manufacturing of waveguide of parabolic antenna. Waveguide is an important electromagnetic wave transmission Component of parabolic antenna. potential benefits of parabolic antenna doesn’t required any cables to transmitte electromagnetic signal. Designing of waveguide was a most important role before its manufacturing. An attempt is made to design and manufacture the waveguide by varying cross- section using CREO software. Manufacturing of waveguide Carried out by milling, the inner pocket of waveguide was machined by Electrical discharge machining process. Which results accurate surface and suitable for travelling of electromagnetic wave without any disturbance.
