    Although the concept of molecular composites (MCs) is very promising, there are major obstacles arising from the immiscibility of the rigid-rod with the random-coil polymers. Here, we developed a novel method for fabricating an in situ reinforced MC system with nonequilibrium self-assembled nanofibrous structures based on bisphenol A epoxy resin, 4,4′ Cited by: 3. The use of Fiber Reinforced Polymer (FRP) composites for strengthening concrete structures has gained a lot of popularity in the past couple of decades. The major issue in the retrofitting of concrete structures with FRP is the accurate evaluation of flexural and shear strains of polymer composites at the bonding interface of epoxy and concrete.

      This treatment strongly modifies the composite fracture behavior. The interface fiber debonding is the main mechanism for untreated fiber composites, while PP disentanglement accounts for the breakage of polymerized fiber composites. The in-situ polymerization method is clearly a very good approach to improve the compatibility between Cited by:   The use of polymer composites in various engineering applications has become state of the art. This multi-author volume provides a useful summary of updated knowledge on polymer composites in general, practically integrating experimental studies, theoretical analyses and computational modeling at different scales, i. e., from nano- to macroscale.4/5(1).

Composites Plates are fabricated by using a Hand lay-up method with different volume fraction (, 1, 2 % v/v) of Nanofibers ratio. Then, the optimum Nanofibers volume ratio (2 % v/v) is reinforced with E-glass fibers and epoxy resin as a : T Vinod Kumar, M Chandrasekaran, V Santhanam, N Udayakumar.

Finally, as regards the bidirectional reinforced composites, it is mentioned that for temperatures below 80 °C a significantly lower CTE is calculated for the ±45° carbon sample as compared to the ±45° glass composite specimen, on the grounds that the axial expansion of the glass fiber itself is larger than the carbon fiber's respective by: 7.

This paper demonstrates how the usual standard tests for characterization of mechanical stiffnesses of glass fiber-reinforced composites can be enhanced by means of photogrammetry.

Examples of application are presented to determine the shear interface strength in carbon and glass fiber composites reinforced with either thermoset or thermoplastic matrices.
