Damage Tolerance of Thin Composite Reinforced Membrane Structures
Structural performance of fiber reinforced flexible composite membranes, designed as pressurized shelters for space exploration, is investigated via computational simulation. An integrated...

Late Stage Damage in G30-500/PMR-15 Laminates
Damage progression has been studied experimentally under tension using [0₂/90₆]_s...

Thermal Regeneration of Spent Lithium Hydroxide
Exploration of planetary surfaces will require portable life-support systems to provide a continuous supply of breathable air. These systems will need to be regenerable in order to support...

Utilization of Liquid Carbon Dioxide for Planetary Exploration
The major component of the atmosphere of Venus and Mars is carbon dioxide CO₂. This proposal is to use this carbon dioxide for planetary exploration...

Carbon Formation Theory for Space Oxygen Processes
Production of oxygen from the Martian atmosphere or lunar soil and the recovery of oxygen in manned space environments may include carbon formation from CO as a unit process. Thermodynamic...

Impulsive Punching of Fiber-Reinforced Concrete Slabs
The behavior of FRC slabs reinforced with polymeric fibers (polyacrylonitrile fibers PAN) and subjected to impulsive punching is analyzed here in order to clarify to what extent the fibers...

FRP Box-Beams Under Long-Time Static and Fatigue Loading
This paper discusses experimental and analytical aspects of the long-time behavior of filament wound E-glass fiber reinforced epoxy-box-beams. Theoretical and experimental data are compared...

Local Buckling of Pultruded FRP Beams: Theory and Experiment
A continuing experimental and theoretical investigation of the local compression flange buckling of commercially produced pultruded fiber-reinforced plastic (FRP) beams is briefly described...

Dynamic Response of Steel Fiber Reinforced Concrete
Extensive research has been done on the static properties of steel fiber reinforced concrete, but very little on the dynamic properties. A total of 20 beams was tested. The steel fiber...

Testing of Concrete Curtain Wall Panels Reinforced with FRP Grids
The objective of this paper is to evaluate the suitability of Fiber Reinforced Plastic (FRP) grids for use as a structural; reinforcement in concrete curtain wall panels. This paper describes...

Bulb-T and Glulam-FRP Beams for Timber Bridges
In this paper, we discusses the manufacturing, analysis, and testing of two glulam beam designers:(1) Southern pine bulb, and (2) yellow-poplar reinforced with pultruded fiber-reinforced...

Anchorage of Non-Metallic Prestressing Tendons
Experimental confirmation tests were conducted to evaluate mechanical and epoxy socketed anchors for fiber reinforced plastic (FRP) prestressing tendons. The studies found that a parabolically...

Nonlinear Analysis of Prestressed Concrete Structures
This paper presents a finite element model for the nonlinear analysis of prestressed concrete structures. The model can be used to analyze pretensioned or posttensioned, bonded or unbonded...

Research of Strength and Deformations with Long-time Loading and the Use of Glassfiber Reinforced Concrete in Shells
Presented is an experimental research on the properties of behavior on compression and tension of glassfiber reinforced concrete of alkali-resistant glass fiber under long-time load and...

Use of Expert Systems in Selecting Equilibrium Isotherms of Organic Compound Adsorption on Activated Carbon
An outline of an Expert System (ES) that aids in selecting adsorption isotherms is presented. Such an ES provides an efficient technique for screening the present literature. The ES helps...

Evaluation of Fe oxide-coated GAC for removal and recovery of Cu(II) from water
A composite solid, prepared by precipitating an Fe oxide onto granular activated carbon (GAC), was evaluated as an adsorbent for the removal and recovery of Cu(II) from water. Relative...

Treatment of Drinking Water Containing Bromate and Bromide Ions
Granular activated carbon and reverse osmosis nanofiltration and hyperfiltration were examined for both bromate and bromide ion removal using surface treated water in New Jersey. Bromate...

Evaluation of Enhanced Coagulation for DBP Control
The paper presents a pilot scale study conducted to examine the control of Disinfection By-Product (DBP) precursors by conventional and enhanced coagulation. The objectives of the study...

Control of Odor and VOC Emissions at Wastewater Treatment Plants -Boston Harbor Case Study-
Siting of the new wastewater treatment plant (WWTP) for the Massachusetts Water Resources Authority (MWRA) in Boston was based on an assumption of mitigation of total reduced sulfur (TRS)...

Effects of Molecular Oxygen and pH on the Adsorption of Aniline to Activated Carbon
This paper examines the influence of molecular oxygen and pH on the adsorption of aniline to F-300 Calgon Carbon. Molecular oxygen increased the adsorptive capacity of GAC for anilines...
