NEW MATERIALS ARE BEING DEVELOPED EVERYDAY AND ARE REVOLUTIONIZING PRODUCTS AND PROCESSES AT AN ASTOUNDING RATE. IN RECENT YEARS, THE ROADSIDE SAFETY APPURTENANCE FIELD HAS BEEN AFFECTED AS WELL, AS NEW MATERIALS HAVE BEEN APPLIED TO PRODUCE IMPROVED DESIGNS IN A VARIETY OF SITUATIONS. IN RECENT YEARS PLASTICS, CERAMICS, HIGH STRENGTH FIBERS AND COMPOSITES HAVE BECOME MORE WIDELY USED IN INDUSTRY ...

OCCUPANT INJURY CAN BE SIGNIFICANTLY REDUCED BY THE INCORPORATION OF PADDING OF HARD SURFACES IN VEHICLE INTERIORS. SEVERAL INTERIOR HARD SURFACES SUCH AS ROOF HEADER, A-PILLAR, AND B-PILLAR ARE DIFFICULT TO PAD DUE TO LIMITED SPACE. WAT IS NEEDED IS AN INFLATABLE PLASTIC BI-LAYER THAT COULD BE ATTACHED TO HARD SURFACES AND GIVE ACCEPTABLE WEAR AND APPEARANCE WHEN UNINFLATED, YET BE INFLATABLE DUR ...

TO FACILITATE TECHNOLOGY TRANSFER OF ON-LINE INFORMATION CONCERNING FEDERAL AVIATION ADMINISTRATION'S R&D PROGRAMS, AUTOMATIC METHODS OF INFORMATION INDEXING MUST BE EMPLOYED. THERE ARE NOT ENOUGH HUMAN RESOURCES TO ADEQUATELY GATHER AND CLASSIFY THIS ABUNDANCE OF DATA. IN ADDITION, AUTOMATEDMEANS OF INTERPRETING THE APPLICABILITY OF NEW TECHNOLOGY AND DETERMINING UNDER WHICH FAA PROGRAM THE TECHN ...

DOWEL BARS HAVE TRADITIONALLY BEEN USED AS AN IMPORTANT LOADTRANSFER MECHANISM ON OUR FEDERAL HIGHWAYS. A SIGNIFICANT PROBLEM OCCURRS WITH THE USE OF THESE BARS DUE TO RUST AND RESULTANT SPALLING AND CRACKING CONCRETE. COMPOSITE REINFORCING BARS (CRB) HAVE BECOME WIDELY USED FOR CRACK CONTROL IN MANY REINFORCED CONCRETE STRUCTURES EXPOSED TO AGGRESSIVE ENVIRONMENTS. A LIMITED AMOUNT OF DATA IS AVA ...

DUE TO THE DOWNSIZING OF AUTOMOBILES ON U.S. HIGHWAYS, MINI-CARS HAVE BECOME A MAJOR PART OF THE AUTO POPULATION. THE LIGHT WEIGHT AND HIGH CRUSH RATE OF THESE VEHICLES CAN CAUSEHIGH VELOCITY CHANGE LEVELS WHEN IMPACTING MOST EXISTING BREAKAWAY LUMINAIRE SUPPORTS. THIS INCREASES THE PROBABILI-TY OF INJURY TO OCCUPANTSOF MINI-CARS WHEN IMPACTING LUMI- NAIRE SUPPORTS. CONCEPTS HAVE BEEN DEVELOPED WH ...

THIS PROJECT INVESTIGATES THE FEASIBILITY OF USING CERAMIC CLADDING MATERIALS TO REPLACE THE METALLIC CLADDING MATERIALS NOW USED WITH WATER REACTOR FUEL. SHOULD FEASIBILITY BE DETERMINED, AND EVENTUALLY COMMERCIALIZED, THE ABILITY OF WATER REACTORS TO WITHSTAND SEVERE ACCIDENTS WOULD BE ENHANCED. WITH TODAYS METAL CLAD FUEL, A RELATIVELY SHORT TIME PERIOD IS AVAILABLE AFTER A LOSS OF COOLANT ACCI ...

A CONCEPT FOR THE DETECTION OF CORROSION IN AGING AIRCRAFT USING ACOUSTIC EMISSION MONITORING IS PROPOSED. CORROSION WILL BE LOCATED THROUGH THE EFFECT THAT IT HAS ON AIRFRAME STRENGTH (10% THINNING RESULTS IN 50% FATIGUE LIFE REDUCTION). ACOUSTIC EMISSION TECHNOLOGY USED ON THE F-111 FIGHTER/BOMBER WILL BE ADAPTED FOR USE ON COMMERCIAL AIRCRAFT. PRELIMINARY CONCEPT TESTING ON A BOEING 720B HAS RE ...
