Composite Repairs
Composite repairs are performed on damaged laminate structures, fibre reinforced composites and other composite materials. The bonded composite repair reduces Stress (mechanics), stresses in the damaged region and prevents cracks from opening or growing. Composite materials are used in a wide range of applications in aerospace, Maritime industry, marine, Automotive industry, automotive, Road transport, surface transport and sports equipment markets. Damage to composite components is not always visible to the naked eye and the extent of damage is best determined for structural components by suitable Nondestructive testing, Non Destructive Test (NDT) methods. Composite structures of interest The composite structures of interest are mainly components composed of Lamination, laminated plies or Sandwich-structured composite, sandwich structures as shown in Figure 1. Laminate structures are assembled so that the fibre orientation provides most of the desired List of materials propertie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stress (mechanics)
In continuum mechanics, stress is a physical quantity that describes forces present during deformation. For example, an object being pulled apart, such as a stretched elastic band, is subject to ''tensile'' stress and may undergo elongation. An object being pushed together, such as a crumpled sponge, is subject to ''compressive'' stress and may undergo shortening. The greater the force and the smaller the cross-sectional area of the body on which it acts, the greater the stress. Stress has dimension of force per area, with SI units of newtons per square meter (N/m2) or pascal (Pa). Stress expresses the internal forces that neighbouring particles of a continuous material exert on each other, while ''strain'' is the measure of the relative deformation of the material. For example, when a solid vertical bar is supporting an overhead weight, each particle in the bar pushes on the particles immediately below it. When a liquid is in a closed container under pressure, each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
