  1. 2. ensures that advanced composite materials meet application performance requirements for intended use in industry AND is a vital part of the product development and production process
  2. 5. geometrically characterized as having a very high length-to-diameter ratio. They are generally stronger and stiffer than bulk material.
  3. 6. he strength with which the material opposes rupture
  4. 7. is the area where the different materials in a composite coincide
  5. 10. the separation of layers from each other in a laminate composite material and it causes reduction in its mechanical strength
  6. 12. thread-like structures that are long, thin and flexible
  7. 13. a region which may develop at the interface between the reinforcement and the matrix and possesses the properties of neither
  8. 16. the uniformed distribution of reinforcement materials within the matrix of a composite
  9. 19. the assembly of two or more materials on a macroscopic scale (macroscale) to form a third with improved qualities
  10. 20. a measure of a materials stiffness or resistance to deformation under stress commonly used in composite material characterization

  1. 1. 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.
  2. 3. Composite materials are processed and cured inside a vacuum bag or a two-sided mold, closed to the atmosphere
  3. 4. the percentage of fiber volume in the entire volume of a fiber-reinforced composite material
  4. 8. reinforcement is a constituent of a composite material[1] which increases the composite's stiffness and tensile strength
  5. 9. a homogeneous and monolithic material in which a fiber system of a composite is embedded
  6. 11. the materials that consist of two or more types of fibers embedded in a single polymer matrix
  7. 14. measures the ability of that material to resist the extension of a pre-existing crack by a specified type of stress
  8. 15. is a combination of two materials with different physical and chemical properties.( they can add strength and be resistant to electricity)
  9. 17. to transfer stress between the reinforcing fibers, act as a glue to hold the fibers together, and protect the fibers from mechanical and environmental damage
  10. 18. a flat or curved arrangement of unidirectional fibers embedded in a matrix
