A novel and simple chemical route was successfully applied to graft carbon nanotubes (CNTs) onto silanized plain weave glass fabric (PWGF) mats, as confirmed by Fourier transform infrared spectroscopy and scanning electron microscopy. The CNTs grafted PWGF mats were used to reinforce epoxy matrix for multi-scale composite production due to their potential for increasing interlaminar fracture toughness by bridging the ply interfaces. Grafting CNTs onto PWGFs improved both initial and steady-state toughness more than double as measured by Mode I interlaminar fracture testing. Failed specimens were visualized to determine the failure modes using fractography. The key findings indicated that the covalent interactions created between CNTs and fibers lead fibers bridging the interface region like barbed wires, which are mainly responsible for increased fracture toughness as a result of improved interfacial adhesion.

An experimental study on low velocity impact performance of bolted composite joints-part 2: Influence of long-term seawater aging

Halil Burak Kaybal, Hasan Ulus, Volkan Eskizeybek, Ahmet Avci

Summary: This paper investigates the low-velocity impact response of bolted fiber-reinforced polymer joints in two scenarios, and evaluates the impact of halloysite nanotubes (HNTs) reinforcement of the epoxy matrix. The effects of seawater aging on the impact performance of the joints are also studied, with results showing a decrease in impact resistance after aging, but an improvement when using HNTs reinforced joints. The ToB impact scenario is considered more detrimental than the SoW tests, and a novel damage mechanism is introduced to address the impact of seawater aging.
