In composites, for a fiber to be considered as a continuous fiber -the fiber density should be 1 g/cm^3 |-length of the fiber should > 15 I_c -length of the fiber should 5 x transverse modulus -Aligned modulus of fiber Solution 1. for a continous fiber , the fiber density should be less than 1 g/cm 3 length of the fiber should be less than 15l c aligned modulus of the fiber should be greater than 5 x transverse modulus 2. True The function of the matrix in a composite is to carry most of the load and deformation is accomplished by slip and dislocation movement. 3.False though compression molding is applicable to thermoplastics parts ,it is more commonly used in manufacturing thermoset plastic parts. 4. False Polystyrene is normally thermoformed has a softening point of below 90 C .The deformation of thermoformed styrene polymer cups when filled with hot beverages can be eliminated by employing temperatures of at least 96C 5. a suitable temperature for stretching the parison into a bottle during blow molding of PET -150C .
