#3 Composite Problem Consider the epoxy matrix C fiber unidirectional pre-preg composite system in CES: What do you estimate the fiber modulus and fiber strength to be (use average properties) What do you estimate the modulus for a balanced 0/90 lay-up? How does it compare to to a woven 0/90 (biaxial) lay-up? What do you estimate the modulus for a "45" ply to be? in the CES software there is a range of volume fraction of fiber and a range...

A new composite grappling hook was purchased for the overhead crane in the turbine building, but the manufacturer lost all records of the volume of fibers used in the process. He is able to say that the fibers are E-glass and the matrix is epoxy, but he doesn’t know the percent of fibers. While a density measurement could estimate the make-up, you decide to test the force at which 1% strain occurs. Carefully gripping the shaft of the hook (which...

A 150 g sample of polyisoprene with a molecular weight of 1000 kg/mol is reacted with 0.75 g of sulfur to produce a rubber network. The product is a 70 cm long strip with a 0.93 g/cm3 density. If you suspend a 10 kg weight from one end of the strip, hung vertically, to what final length will the material stretch? Note that the area to which the force is attached is not given but can be determined by (volume)/(length).
