WebAug 26, 2013 · Multiplying the MFR by approximately 2.2 will give the shear rate at which the test was performed. So a 4-melt material is tested at a shear rate of about 8.8 sec-1 while the 20-melt material is tested at 44 sec-1. Not only are these shear rates different, they don’t represent the shear rates experienced by polymers under most melt processes. WebThe matrix resins were also tested. The neat resin DMS indicates large changes in resin viscosity during cure that are not reflected in the corresponding prepreg spectra. Thus, the …
