Abstract : Thermoplastic resins have been used extensively in industry primarily in unreinforced molded assemblies or reinforced with chopped glass fibers or mat; both are considered essentially non-structural or secondary structural applications. The thermoplastics are selected for these applications for their low cost, ease of formability and processability and good environmental resistance Their entrance into the structural composite field had been hampered by their low heat distortion temperature, low mechanical properties and poor creep characteristics. In recent years, however, the development of several new thermoplastic resins has minimized these disadvantages, while retaining the processability and other favorable attributes.
