  1. 3. Hybrid composites are materials in which one type of reinforcing material is incorporated into two polymer matrix mixtures, or a particular polymer matrix is reinforced with more than one reinforcing material
  2. 6. Metal dispersion, typically defined as the ratio of the number of surface atoms to the number of total atoms, should be increased2,3, as a catalyst with a higher metal dispersion often exhibits higher catalytic activity
  3. 12. Filler materials are particles added to resin or binders (plastics, composites, concrete) that can improve specific properties, make the product cheaper, or a mixture of both.
  4. 13. an interface is the boundary between two spatial regions occupied by different matter, or by matter in different physical states. The interface between matter and air, or matter and vacuum, is called a surface, and studied in surface science.
  5. 14. one way of expressing the composition of a mixture with a dimensionless quantity; mass fraction (percentage by weight, wt%) and mole fraction (percentage by moles, mol%) are others.
  6. 15. Optimum strength and stiffness can be achieved in a composite by aligning the fibres parallel to the direction of loading. However, in this case, the composite can perform very poorly when the load is applied perpendicular to the fibres.
  7. 16. a combination of two materials with different physical and chemical propertiesa combination of two materials with different physical and chemical propertiesa combination of two materials with different physical and chemical properties
  8. 18. In polymer chemistry and materials science, a resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses mainly on naturally occurring resins.
  9. 19. A composite that has the fibers all facing in one direction so that they are all aligned parallel to one another. A unidirectional composite is extremely strong when the force is applied in the direction that the fibers are facing. It is weaker when the force is applied in the direction perpendicular to the fibers.
  10. 20. Fiber is a hair-like strand of material that is extremely long in relation to its width, typically more than 100 times longer than it is wide.

  1. 1. An interface material (interphase) is deposited on the fibers. This interphase acts as a deflection layer for the matrix cracks. It consists essentially of Pyrocarbon, Boron Nitride or a multilayer ((PyC/SiC)n or (BN/SiC)n sequences).
  2. 2. Continuous fiber composites are advanced materials that combine high-strength fibers with a supportive polymer matrix.
  3. 4. a constituent of a composite material which increases the composite's stiffness and tensile strength.
  4. 5. Delamination is the separation of layers from each other in a laminate composite material and it causes reduction in its mechanical strength.
  5. 7. A ply is a layer of material which has been combined with other layers in order to provide strength. The number of layers is indicated by prefixing a number, for example 4-ply, indicating material composed of 4 layers.
  6. 8. A particulate composite is characterized as being composed of particles suspended in a matrix. Particles can have virtually any shape, size or configuration.
  7. 9. Woven fabric is any textile formed by weaving. Woven fabrics are often created on a loom, and made of many threads woven on a warp and a weft.
  8. 10. Laminate composites are orthotropic, consisting of multiple layers of oriented or randomly oriented fibres bound together by a matrix in which each layer of fibres has a two-dimensional (ie, planar) orientation.
  9. 11. monolithic material in which usually the reinforcement is embedded and must be uniformly distributed throughout the matrix
  10. 17. In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing. Toughness is the strength with which the material opposes rupture.
