Interfacial bond strength

The main aim of this study is to investigate utilising root-like architectures to improve the interfacial strength of pin-integrated hybrid composite-metal structures. Joints are critical elements in aircraft structures and require special consideration due to their vital role in the structural integrity of airframes. Although bonded and bolted systems are used commonly in engineering applications, pinning technologies have shown tremendous potential for hybrid joints.

Portland cement concrete (PCC) / asphalt concrete (AC) bonded components are seen in both conventional pavement structures as well as overlays. Due to the environmental and traffic loads, cracks occur at the interface of the PCC and AC layers and finally, may propagate through the interface or one of the layers.

Two chemical treatments were applied to jute fibers to create a better bonding of fiber to resin in natural composite materials. The jute fibers have been treated with hydroxide potassium (KOH) and a bleaching agent, canxi hypochlorite (Ca(OCl)2.4H2O), in varying periods. Characterization techniques such as FT-IR, SEM were used to evaluate the effect of chemical treatments on fiber structure. After treatment the surface topography of jute was clean and microfibrils were revealed, these lead to an enhancement in mechanical properties and interfacial strength between jute fiber and PP.
