Recyclable Vitrimer-Matrix Carbon-Fiber Composites for Aerostructures: Reprocessing Efficiency and Retention of Mechanical Performance
Abstract: To begin with, carbon fiber reinforced polymers (CFRP) have become an important part of the structural loading in many modern aircraft; however, due to their permanent cross-linking in thermosets, they cannot easily be restored after being retired. Vitrimers have been proposed as a solution since their Covalent Adaptable Networks (CANs), rearranged by associative exchange, may be reshaped, welded, repaired or dissolved without damaging the CFRP fibers. This paper reviews whether …

Experimental Determination of Tire Stiffness using Nitrogen
Abstract: Vehicle stability generally depends on the tire forces and torque at wheel. Forces and reactions generated at tire play major role in the control of vehicle. On application of torque to the wheel, due to contact friction between road, tire pushes on the ground and moves forward and backward. Tire also supports the load of vehicle and deforms under load for the flexibility and damping. The stiffness of fluid in …
