Abstract: A method and sealant to seal microcracks as small as 50 ?m by causing methyl methacrylate combined with one or more nanoparticles to flow into the microcrack to be sealed.

Abstract: A break-away coupling is formed of metal and has a central axis and a necked-down central region formed by two inverted truncated cones each having larger and smaller bases. The cones are joined at the smaller bases by a narrowed transition region having an exterior surface formed by a curved surface of revolution having an inflection point of minimum diameter substantially midway of the coupling along the axis. The cones each define an angle ?1 and ?2, respectively, at each of the larger bases, wherein both ?1 and ?2 are selected to be within the range of 20°-40° and, preferably within the range of 30°-37°.

Abstract: A 3D printed fiber reinforced polymer composite having a nonlinear stress-strain profile created by a central layer and a plurality of recruited successive layers.

Abstract: A method and precursor for making carbon fibers and the like comprising carbon black modified with at least one cyclic compound promoter. A source of the carbon black may be recycled materials such as recycled tires or recycled plastics. The carbon black is modified by attaching at least one cyclic compound promoter to the outer periphery of the carbon black.

Abstract: A 3D printed fiber reinforced polymer composite having a nonlinear stress-strain profile created by a central layer and a plurality of recruited successive layers.

Abstract: A glass fiber reinforced polymer reinforcing structure comprised of glass fibers mixed with one or more polymers. Incorporated in the polymer are a hybrid mix of pristine multi-walled carbon nanotubes at 0.0-4.0 wt. % of the polymer and multi-walled carbon nanotubes functionalized with carboxylic group at 0.0-2.0 wt. % of the polymer. The above mixture is pultruded to produce GFRP reinforcing bars, dowels or structural profiles.

Abstract: An unmanned aerial vehicle (UAV) and laser generator may be used to measure structural displacements. The system may measure relative movement of the UAV and the structure, as well as individual movement of the UAV. The individual movement of the UAV may then be subtracted from the relative movement of the UAV and the structure, in order to accurately calculate structural displacements.
