The optimal fiber volume fraction and fiber-matrix property compatibility in fiber reinforced composites

摘要: Although the question of minimum or critical fiber volume fraction beyond which a composite can then be strengthened due to addition fibers has been dealt with by several investigators for both continuous and short composites, study maximum optimal at reaches its highest strength not reported yet. The present analysis investigated this issue case based on well-known shear lag (the elastic stress transfer) theory as first step. Using relationships obtained, spacing between is determined upon calculated, depending packing forms within composites. effects value such factors matrix properties, aspect ratio are discussed. Furthermore, combined previous fraction, used examine property compatibility in forming composite. This deemed useful design. Finally some examples provided illustrate results.
