Write two suitable solutions to overcome each of the following problems: 1. Poor dispersion of reinforcement during the production of PMC's using an internal mixer. 2. Poor impregnation of reinforcement during the production of PMC's using an continuous melt impregnation by extrusion-calendering process. 3. High void content during the production of CMC's using conventional mixing and pressing. Q2- Write two main differences between each of the followings: 1. Film stacking and powder impregnation that used to produce PMC's. 2. Liquid state and solid state processes used to produce MMC's. Q3- A hybrid continuous fibrous unidirectional composite contains two fibers and a polymeric matrix, the volume fraction and the properties of each constituent are given in the following table. Material Tensile strength (MPa) Tensile modulus (GPa) Volume fraction Matrix 30 0.2 Fiber 1 200 1 Fibers 2 300 2 0.5 0.2 0.3 1. Calculate the traverse tensile strength of the composite material. 2. Calculate the percentage of stress carried by fiber 1 just before fracture. 3. If a stress of 10 MPa is applied parallel to the fibers direction, calculate the strain. 4. If the fibers are randomly distributed in the polymeric sheet, calculate the tensile strength of the composite. Write two suitable solutions to overcome each of the following problems: 1.
