A Study Of Rubberfatigue Life And Cure Parameters, Jack Alberts
A Study Of Rubberfatigue Life And Cure Parameters, Jack Alberts
Master's Theses (2009 -)
is demand for increasing rubber life in parts within medium and heavy duty suspension systems. Rubber plays a major factor in lightening the overall weight of the suspension system; therefore, increasing the hauling capacity of the truck. This thesis focused on optimizing the cure time and cure temperature of the manufacturing process as it relates to the fatigue life of rubber suspension parts. Samples of rubber parts were made using molding techniques with different process parameters, specifically cure time and temperature. These samples then underwent a series of nondestructive tests, to quantify, for example, dynamic stiffness, and then a destructive …

Epoxy thermosets are important engineering materials with applications in coating, adhesives, packaging and as structural components in a variety of advanced engineering products. The ultimate performance of polymer critically depends upon the details of the cure chemistry used to produce the thermoset. In order to better understand and monitor the cure chemistry, quantitative analysis of the FT-IR response has been developed for describing the epoxy-amine curing reaction as well as monitoring the hydrogen bonding that occurs in these systems The FT-IR analysis includes (i) quantitative deconvolution of complex peaks into individual spectral contributions, (ii) peak identification via DFT analysis and …
