Crushing Response of Energy Absorbing Composite Structure
A description of why and how composite structures crush and absorb energy is presented. The three primary crushing modes of composite structure (transverse shearing, lamina bending and...
Flexural and Shear Studies of Carbon Fiber Reinforced Beams
This paper presents the results of laboratory test on beams reinforced with three dimensional continuous carbon fiber grid. The grid is prefabricated by three-dimensional weaving and epoxy...
Constitutive Modeling of Slurry Infiltrated Fiber Concrete (SIFCON)
Slurry Infiltrated Fiber CONcrete (SIFCON) is a unique material, containing 5 to 18 percent, by volume, of steel fibers; in contrast, standard Fiber Reinforced Concrete (FRC) usually contains...

A brief description is given of the mechanisms associated with the bond shear stress versus slip response of deformed reinforcing bars embedded in slurry infiltrated fiber concrete (SIFCON)....
Optimization of Discontinuous Fiber Composites
Discontinuous Random Fiber Reinforced Composites (DRFRC) exhibit different behaviors depending on their microstructural properties. Small fraction of fiber rupture can have a beneficial...
Stresses in Open Section Fiber Reinforced Composite Beams Under Constant Shear Loading
A strength of materials approach from the ply level is used to derive expressions for stresses in statically determinate open section composite beams subjected to constant shear loading....
The Effect of Multiple Compliant Layers at the Fiber-Matrix Interface on Residual Thermal Stresses in Metal Matrix Composites
The large mismatch in thermoelastic properties of the fiber and matrix phases in advanced metal matrix composites, coupled with high consolidation temperatures, produces severe residual...
Measuring Vibration in an Advanced Composite Beam with Localized Internal Fiber-Optic Strain Sensors
Two optical fibers embedded with different configurations were used separately as strain sensors to measure the natural frequencies and modal amplitudes of a cantilevered graphite/bismaleimide...
Composite Materials for Structures on Planetary Surfaces
Development of structures for planetary surface environments depends upon the use of the most appropriate materials. Advanced composite materials are apparently the best candidates for...
Comparison of Micromechanical Models for Elastic Properties
The effective elastic properties for unidirectional composites, as predicted by several analytical micromechanical models are compared for glass/epoxy and graphite/epoxy. A brief review...
Optimum Design of Laminated Composites
The increased demand for high strength, light weight materials that function successfully in high temperature environments has caused the effective development of laminated composites...
