Carbon fiber/vinylester composites in the marine environment: EIS as a means of determining an effective composite interfaceUnknown Date (has links)
In this research, the degradation of carbon fiber/vinylester composites in marine environments was experimentally investigated. Additionally, two types of carbon fiber surface treatments, namely Polyhedral Oligomeric Silsesquioxane (POSS) and the industrial surface treatment F0E, were evaluated to determine their effectiveness in creating a fiber/matrix (F/M) interface for use in the marine environment. Electrochemical Impedance Spectroscopy (EIS) was explored as a new application of an existing technique for use in measuring the amount of water at the F/M interface in carbon fiber/vinylester composites. EIS spectra were used to determine equivalent electric circuit models that allow for the prediction of water at the interface. The location of water within the composite was determined through Positron Annihilation Lifetime Spectroscopy (PALS). Interlaminar shear strength and transverse tensile tests were carried out for dry conditions and after hygrothermal exposure of the composites to study the influence of the integrity of the F/M interface on the macroscopic response of the composite. / by Chris J.

Fiber-reinforced composite materials for coal transportation railcar bedZhou, Junlin 04 June 1999 (has links)
The material properties of the candidate fiber-reinforced composite materials
and different fabrication methods for fiber composites were discussed. The
improvement of the hand lay-up process for polyurethane impregnated Kevlar was
investigated. Testing samples for lab and prototype tests were fabricated by hand lay-up
process. The study showed that fiber composites fabricated by the hand lay-up
process can achieve good properties, and advanced fabrication methods could be
applied In industrial manufacturing processes to improve the fiber composite
properties.
A nonlinear static analysis was discussed. The ANSYS finite element analysis
computer program was used to build stress analysis models, simulate the loading
conditions, and perform the nonlinear static analysis. The tensile strength proof test
was designed and done by using a microcomputer controlled Instron 4505. It showed
that the different types of fiber composites can meet the strength requirements for the
application. Polyurethane impregnated Kevlar showed the best strength properties
among the different types of fiber composites, which were fabricated and tested.
The wear and abrasion properties of the different types of fiber composites
were discussed and relevant tests were introduced. An ultraviolet light exposure test
and the Oregon Department of Transportation road-cover test were conducted.
Moisture and acid resistance and cost analysis were also discussed.
Based on the results of the study, a prediction of the optimal fiber-reinforced
composite materials was made. Also, various conclusions and recommendations for
future research work were made. / Graduation date: 2000
