We report on a green method of using poly(oxypropylene) diamines (D 400 ) as coupling and curing agent to functionalize carbon fiber in water. We propose to enhance the interfacial properties of carbon fiber composites, together with the tensile strength of carbon fibers. The microstructure and...

Low-dimensional materials could improve the interface strength between the epoxy resin and carbon fibers (CFs) in the composites. Four type of low-dimensional powders were employed to functionalize the CFs/epoxy interface, and their reinforcement efficiency were compared by performing CF bundle pull ...

In present day the use of fiber reinforced composites is increased remarkably in the various sectors of industries owing to its relative advantages especially in industries like aeronotics, automobile, ship buildingand in chemical industries, where the major emphasis is on weight reduction with a sub...
In comparing these results with identical tests on finegrained freshwater ice it was found that for comparable loading conditions, the strength of the sea ice was significantly lower than the strength of the freshwater ice, whereas the fracture toughness of the sea ice was higher than the ...
can be configured by modifying the parts of the testing equipment. The radius and surface area of the dolly, or bonded probe, can be modified to increase the maximum pull-off strength that can be tested. This dolly is glued to the surface to be tested with a resin, usually an epoxy. ...
Influence of stacking sequence and halloysite addition on the fracture toughness and low-velocity impact strength of carbon/glass fiber reinforced hybrid c... The objective of this study is to produce bidirectional woven carbon/glass fiber reinforced epoxy hybrid composites and to assess their fracture...
The cellulose microfibrils (hereinafter referred to as “microfibrils”) used in the invention refer to microfibrillated cellulose fibers. The degree of microfibrillation can be evaluated, for example, using water retention as an indicator.
In the test setup, the FRP sheets were mounted on the masonry blocks using epoxy, and the tensile loading was applied to the FRP sheet to pull it out. Consequently, by considering supports applied perpendicular to the direction along the loaded FRP, the stability of the setup was satisfied....
