Evaluation of Mechanical Properties of E-Glass Fiber Reinforced Polyurethane for Wind Mill Blades

Mechanical Engineering

Polymer composite materials have been a part of the automotive, domestic, agriculture and aerospace industries for several decades. Polyurethane is one of the latest members of the rapidly growing thermoplastic polymer family which is capable of successfully competing currently with textile, chemical, automobile, aerospace applications, radar, marine applications, industrial products, building and packaging industries. Polyurethane is the first member of a new group of polymers prepared by a mechanism defined as "Steriospecific" polymerization. From a simple monomer, this technique produces polyurethane with an exceptionally uniform molecular structure, which imparts outstanding engineering properties into the polymer. Such structural regularity as well as low weight to strength ratio can be varied to tailor the properties of the polymer to satisfy a given requirement in the wind mill blades.
