Aluminum Metal Matrix Composites (AMMCs) are promising as the most flexible materials for advanced in automotive, structural, aerospace, aviation, marine, defense applications and other interrelated sectors because of their tremendous combination properties. In this work we have taken Al 7075 -SiC- Granite dust. By varying the weight percentage of Al 7075 (75%, 80% and 85%) and the reinforcement materials like SiC (15%, 10% and 5%) and taking Granite dust as constant (10%), by using stir casting technique the material is fabricated.
The wettability of SiC and Granite dust particles in the matrix was improved by adding them. The optical and scanning electron micrographs showed a homogeneous dispersion of composition material. The result shows that the Sample-3 (Al85%+SiC5%+Granite dust 10%) shows improvement in mechanical properties like hardness, the wear properties has been reduced and their Micro structural characterization clearly shows uniform distribution of SiC and Granite dust in the composition.

The customer demands on micro component usages have been increased in past some of the decades. So, the development is necessary to achieve desired smaller shape and size of components with high accuracy. In this work, blind-hollow cylindrical micro-hole fabrications of various diameter (0.5 x 0.7 mm, 1 x 1.4 mm and 2 x 2.8 mm) on Titanium grade (Ti6Al4V) were processed by Nd:YAG laser machine. The design of experiment, Analysis of Variance (ANOVA) techniques and effect of process parameters has been implemented to assess performance. The performance characteristics of the blind-hollow cylindrical micro-hole fabrication were evaluated through circularity and Feret’s diameter. The laser tuning parameter such as current, pulse frequency and air pressure were considered as input laser parameters.Keywords

The worldwide interest for wood as a structure material is consistently developing, while the accessibility of this normal asset is lessening. This circumstance has prompted the advancement of elective materials. The paper is to manufacture the composite material for light weight applications. The green gases produced by plastics over the long haul will contaminate the climate. The time has come to fix an option in contrast to the plastics. We have discovered common fiber as the reasonable substitution. We have discovered regular fiber as the appropriate substitution. The common fiber having the few favorable circumstances yet despite the fact that some primary disadvantage additionally presents in the fiber. In this venture palmyra fiber is favored as a composite material. In any case, the fundamental inconveniences of characteristic strands in composites are the helpless similarity among fiber and grid. To defeat this issue, explicit physical and compound medicines were recommended for surface change of filaments by agents. Salt treatment is one of the basic and viable surface alteration procedures which are generally utilized in common fiber composites.Keywords
