Feasibility of fiber reinforced composite materials used in highway bridge superstructures
(Virginia Tech, 1988-12-05)
<p>Composite materials are considered here as structural materials of highway bridge superstructures. Bridge deck designs can be done according to <i>AASHTO</i><sup>1</sup> specification and elastic design concepts. </p><p> ...
Indentation testing of composite materials: a novel approach to measuring interfacial characteristics and engineering properties
(Virginia Tech, 1991-03-05)
Findings made through the indentation testing of composites are presented in this thesis. The concept was developed as an attempt to evaluate the interfacial shear strength at a mesolevel, possibly overcoming the deficiencies ...
Variable complexity modeling of postbuckled stiffeners for delamination initiation
(Virginia Tech, 1993-06-18)
Delamination at the free edge is analyzed as a mode of failure for uniaxial compression of postbuckled structural components. Analyses are performed for I-section stiffeners and for a dropped-ply laminate, all of which ...
Investigations of flakeboard mat consolidation
(Virginia Tech, 1994-10-05)
<p>The response of a flake mat to the mechanical stress applied during consolidation is a function of mat structure, raw material properties and the environmental conditions created during pressing. This research project ...
Development and verification of a resin film infusion/resin transfer molding simulation model for fabrication of advanced textile composites
(Virginia Tech, 1994-12-05)
<p>The objective of this study was to develop a two-dimensional computer model for the simulation of the resin transfer molding/resin film infusion processing of advanced composite materials. This computer simulation model ...
Effect of fiber morphology on composite properties
(Virginia Tech, 1988-05-05)
</p>The effect of the cylindrically orthotropic morphology known to exist in graphite fibers on the effective properties of a composite material was studied using the composite cylinder assemblage model. The cylindrical ...
