A multi-scale carbon fiber reinforced polymer nanocomposite laminate, with strategically incorporated fluorine functionalized carbon nanotubes at 0.2 weight percent, is studied for improvements in strength, stiffness and fatigue life under both tension-tension fatigue (R = +0.1) and tension-compression fatigue (R = −0.1) loading. The nanotubes were incorporated into the carbon fabric, and laminates were fabricated using a high temperature vacuum assisted resin transfer molding process. The influence of the fluorinated functionalized carbon nanotubes on the evolution of damage and the resistance to catastrophic failure is credited for these mechanical property improvements.

This paper do the research of molding process, experimental study, numerical simulation for carbon fiber reinforced polymer (CFRP) sandwich structure under an aircraft ditching model. The model is simultaneous restricted to the weight and strength requirements. Choosing three types of expandable polystyrene (EPS) foam, testing their properties in different kinds of conditions: density, thickness of the core, layer. By the experiment to verify the design, we can gain the optimized layer, thickness of the core and parameters. This project can provide the basis to the design of manufacturing, process parameters and weight control for CFRP sandwich structure on aircraft ditching model.

The present investigation aims at studying the effect of carbon nanotubes dispersion on the surface hardness of carbon fiber-reinforced polymer composites, manufactured by means of compression resin transfer molding. The influence of the weight fraction of nanofiller, distributed in the epoxy matrix, on the Vickers hardness values was investigated. Furthermore, the evaluation of carbon nanotubes filtering effect was also taken into account by comparing the hardness values measured at the top and bottom surfaces of the laminate composites. It was observed that the different weight loads affect the surface properties of the nano-composites, both in terms of hardness and filtering effect.
