Composite materials (also called composition materials or shorte ned to composites) are materials made from two or more constituent materials with significantly different physi cal or chemical properties,that when combined,produce a material with characteristics different from the i ndividual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons:common examples include materials which are stronger,lighter or less expensive when compared to traditional materials. In the last decades,the use of natural fibers as r einforcement in polymeric composites for technical application has been a research subject of scientist. Interest in natural fibers has increased worldwide due to their low cost,low density,hardness,higher fatigue endurance,good thermal and mechanical resistivity and to their environmental friendliness. The Asian markets have been using natural fibers for many years e.g.,jute is a common reinforcement in India. Natural fibers are increasingly used in automotive and packaging materials. India is an agricultural country and it is the main stay of Indian economy. Thousa nds of tons of different crops are produced but most of their wastes do not have any useful utilization. Agric ultural wastes include wheat husk,rice husk,and their straw,hemp fiber and shells of various dry fruits. These ag ricultural wastes can be used to prepare fiber reinforced polymer composites for commercial use.

Mechanical Behaviour of Agricultural Residue Reinforced CompositesScientific Review
The increasing awareness and the quest for newer materials have given renewed interest to the development of green composites. This article focuses on the potential use of abundantly available waste agricultural residue for the preparation of composites. The mechanical properties of Rice straw fibers reinforced with Polyester resin, Vinyl ester resin and Isophthalic polyester resin are studied and compared. Hand Layup technique is used to prepare the samples on which flexural and impact studies are made. Samples are made using different volumetric compositions of fiber and resin. The results show that the Vinyl ester resin and Isophthalic resin offer good mechanical properties when compared to the polyester resin. Both these resins show similar behavior with respect fiber loading. The flexural strength decreases with increasing fiber loading for polyester resin and increasing trend is observed for both vinyl ester and isophthalic resin. Impact strength increases for the increase in fiber loading up to a certain limit and then decreases. It can be concluded from this study that the agro-waste materials are attractive reinforcements from the standpoint of their mechanical properties.

Preparation and characterisation of alumina nanocomposites with aramid fibre ...eSAT Journals
Abstract
The requirement of light weight and high strength materials are ever increasing in the industry. Lot of research is going on worldwide for improvement of mechanical properties of light weight non-metallic composites. Researchers are trying to meet the industrial requirements by modifying properties of composite materials by making nanocomposites. Nanocomposites are formed by mixing two or more dissimilar materials and adding nanoparticles in order to control and develop new and improved materials and their properties. The properties of composites depend not only upon the individual components used but also upon the morphology and the interfacial characteristics of the ingredients. This novel feature forms the basis of hypothesis to be investigated.
In the investigation for high strength materials, laminates of epoxy resin and nanoparticles of Al2O3 as filler are used with Aramid fibre, hybrid of carbon and aramid fibre as reinforcement are produced. Nanoparticles of Al2O3 of 20-30nm size are first dispersed in methanol by mechanical stirring. The solution is further sonicated for effective dispersion of nanoparticles. The mixture of methanol and Al2O3 nanoparticles are mixed in preheated Epoxy resin and mechanically stirred. During mixing some of the methanol is evaporated. Further, the remaining methanol is removed by heating and drying. Then, Hardener is mixed with the mixture of epoxy- Al2O3 and laminates are prepared. The laminates are cut to the required size of test samples for mechanical tests. It is observed that the mechanical properties are improved with the addition of nanoparticles of Al2O3.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
