An intensive way of farming fishes is thecomposite fish culture system. In such a system, five or six different species of fishes are grown together in a single fishpond. In such a system, five or six different species of fishes are grown together in a single fishpond.

Composite Variable: Definition and Concept. Variables in Social Science. In statistics, Advantages and Disadvantages in Using Composite Variables.
A composite material is a material that combines two or more materials with the aim of improving the properties of the material and has clear boundaries including those during molding in the material.
Answer . A composite is any material made of more than one component. Polymer composites are composites made from polymers, or from polymers along with other kinds of materials.

Composites And Its Classification, Advantages, Disadvantages Written by admin Published in AutoCAD Comments off Composites are defined as the combination of two or more chemically different constituents which combines macroscopically to produce a useful material.
Disadvantages. Also, the resin used in composite material weakens at temperatures as low as 150 degrees, making it important for these aircraft to take extra precautions to avoid fires. Fires involved with composite materials can release toxic fumes and micro-particles into the air, causing health risks.
Composite materials composites are made when two or more materials with different properties are combined to produce a new material. The physical and chemical properties of each of the constituent materials remain distinct in the new material.
Although not covered by this bpok, metal and ceramic qmtrix composites are being studied intensively. Composites in structural applications have the following characteristics: 1.3 Advantages and Disadvantages of Composites Composite parts have both advantages and disadvantages when compared to the metal parts they are being used to replace.

A composite endpoint is an endpoint that is a combination of multiple clinical endpoints. Composite endpoints can be primary or secondary: Primary composite endpoints are the main measurements for a trial; They answer the most important questions in the trial.
Pottery. Pottery is made by moulding clay into the desired shape and baking it in a kiln. The high temperature drives out all the water, and causes chemical reactions that make the clay stronger and harder. Pottery is usually decorated with a tough, coloured glaze. Like bricks, it is hard and strong, but also brittle.
Like st, the fiber provides the structure and strength of the composite, while a plastic polymer holds the fiber together. Common types of fibers used in FRP composites include: Fiberglass. Carbon fiber. Aramid fiber. Boron fiber. Basalt fiber. Natural fiber wood, flax, hemp, etc.
Disadvantages: Of course, daily-use ceramics also have the fly in the ointment, the biggest weakness is low impact strength, impenetrable touch, easily damaged, is a fragile good, there are cracks recommended not to use, more easily broken, hidden dirt is not clean May produce bacteria.
That gives us the three main types of modern composite materials: metal matrix composites MMC , polymer matrix composites PMC , and ceramic matrix composites CMC . Metal matrix composites MMC These have a matrix made from a lightweight metal such as an aluminum or magnesium alloy, reinforced with either ceramic or carbon fibers.
Topic 8. Composite materials I Properties to take into account for material design For ceramic and metallic component: Physical thermal, electrical, optical and mechanical stiffness, toughness, stress-strain behaviour For plastic components: Physical and mechanical.
Composite materials offer higher specific strength and stiffness than other conventional materials. Readily available carbon fibre composites will match the stiffness and strength of high-grade aluminium in all directions, at less than two-thirds the density.
In addition, because thermoset composites have a low petroleum-based content, they are not subjected to the price fluctuations experienced in petroleum-based products. Seven Trustr material costs Because thermoset composites can be precisely molded, there is little waste and therefore significantly lower overall material costs than metals products.
Keywords. The composite is non-metallic, contains no mercury, is thermally and electrically inert, possesses the ability to directly bond with hard tooth tissues, and ensures a satisfying aesthetic appearance of a natural tooth 3, 4 . The bond between tooth and composite has always been a sensitive issue in science,
Composites Science and Technology publishes refereed original articles on the fundamental and applied science of engineering composites. The focus of this journal is on polymeric matrix composites with reinforcements / fillers ranging from nano- to macro-scale.
Fiber-reinforced composites offer an alternative which has spread rapidly in the transport industry. Researchers now outline the advantages of new lightweight materials.
Pre-preg is "pre-impregnated" composite fibers where a thermoset polymer matrix material, such as epoxy, or a thermoplastic resin is already present. The fibers often take the form of a weave and the matrix is used to bond them together and to other components during manufacture.
and i am going to tell you about the different kinds of composite materials. i am going to tell you the advantages and disadvantages of composite materials. also the people that work with composite materials. types of composite materials there are various types of composite materials and here are two examples:- carbon fibre and fibre glass.
