I am working on textile composites but the words hybrid and composites confuse me as they are used exclusively and I want to measure transparency of textile fabric also.
Hybrid materials are mixtures of two or more materials with new properties created by new electron orbitals formed between each material while composites are mixture of materials consisting of a matrix with micron-level and Sub-micron level dispersion of similar kinds of materials
To measure transparency you can use UV-vis specrtrosctropy and find out the transmittance of the material
One usually speaks of hybrids if a polymer composite is produced by in situ filler formation (e.g. by sol gel method in the polymer matrix). Hybrid resins may indicate various organic resins co-cures and intimately mixed together. Theferore hybrids consitute a special class of composites. Composites may include fiber or particle reinforced systems impregnated by melt impregnation, melt mixing, fluid reisn impregnation followed by curing etc.
In general....composites are multiphase materials, where one phase (called filler) is dispersed in a second phase (matrix). They are more simply obtained at the macroscale level by simple mixing techniques (e.g. ball milling, shear mixing etc) . In the composite materials, the properties of the two phases are added up.
In the hybrids materials, instead, the constituents combine at a nanometer or molecular level, and therefore there is a situation of orbital interaction. This leads to new material that can exhibit new properties not necessarily found in the individual components.
Hybrid materials are defined as mixtures of two or more materials with new properties created by new electron orbitals formed between each material
Composites are defined as a mixture of materials consisting of a matrix with micron-level and Sub-micron level dispersion of similar kinds of materials.
Transparency can be measured by using UV- VIS specrtrosctropy and find out the transmittance of the material.
You are very welcome Dr. Iftikhar. I really appreciate that Thank you again
Hello all. I found this discussion interesting. I will like to ask too; can someone refer to Cu reinforced with SiC as hybrid nanocomposite; assuming that Cu is submicrons and SiC is nano. Both are ball milled and sintered.
The difference between "composites" and "hybrids" can be better understood by developing an analogy of the difference between a mixture and compound.
compound does not contain or not necessarily contain the properties of its individual elements whereas mixture does have.
Similarly, the composites are formed by just mixing materials at macro level whereas the hybrids are formed by proper nano-level mixing of individual materials which gain completely different properties/mostly.
I also have this confusion but now after reading these my confusion is clear. Thanks to all who gave answers.
