Regular grit are those which are made normally, for example, Abaca, Jute, Hemp, cotton, hair, fleece coir and etc. Because of numerous points of interest Ordinary grit are supplanting glass grit and carbon grit, for example, its biodegradable nature so it dumps it beyond all detectable inhibitions space after it takes retirement, and its simplicity of accessibility, low weight, and better quality in multi hub support with including Nano powder particles with it. In this examination work motorized conduct of Flyash Nano powder/Abaca/Agave grit strengthened epoxy based half and half compounds and its creation has been considered. Work has been done to examine the flexural properties,tensile quality, hardness, and effect quality of the compounds. It has been seen that effect quality is improved with the expansion in the weight portion of normal strands to certain degree. The morphology of compounds is contemplated by utilizing Scanning Electron Microscope (SEM)

“When a single cotton hair or fiber is exposed to a moving airstream, it experiences a fractional force induced by the relative movement of the air near the fiber surface. This force, known as aerodynamic drag, was measured for several cottons, each having a different Micronaire reading. Individual fibers were selected for fiber fineness and installed in a specially designed wind tunnel apparatus. Drag-force measurements for crossflow velocities from 12 to 280 cm/sec were recorded. Correlation of the test results show that aerodynamic drag coefficient for all cotton fibers can be expressed by the relation Cd = 10.35/Re0,825 for the 0.07 to 0.8 Reynolds number range, and Cd = 10.8/Re0,876 for the Reynolds numbers from 0.8 to 3. Laminar flow drag theories for smooth circular cylinders in crossflow are compared with the data recorded for cotton fibers.

The cellulose fibre has been investigated frequently in recent years, from both the chemical and physical points of view. Special attention has been paid to the minute details of visible structure, not only in connection with the problems of cellulose molecule arrangement but also as they may have a bearing on the technical problems of the textile industries. Summing our knowledge briefly, plant fibres have been shown to have a concentric structure of spirally disposed cellulose aggregates, with both crystalline and colloidal properties. Balls (1) in 1919 was able to link up the concentric structure of the cotton hair with the simple factor of a daily increment of growth. Reimers (2) in 1921 gave a useful summary of work on cellulose fibres, with special reference to the spiral arrangement of the fibre components, whilst Nodder (3) in 1924 brought this matter more up to date and extended our knowledge in several directions. The present brief communication records another phenomenon, which apparently has escaped notice before ; namely, a transverse lamellation with a tendency under certain conditions for fibres to segment into thin sections perfectly transverse to the longitudinal fibre axis. This phenomenon was first described and illustrated by Searle (4) in a paper on chemically tendered flax fibres, but little attention was given to it at the time, as it appeared to have occurred more by accident than by design.
