Abstract The welding of thermoplastic pipes under a shear joint configuration using friction spin is investigated. consists two cylindrical and concentric polypropylene plastic parts joined with each other at their interfacing surfaces through frictional heat generation. effects pressure rotational velocity on the overlap distance strength between are evaluated. study specific application in ma...

Abstract The goal of this work is to evaluate the potential diamond-like carbon (DLC) coatings on thermoplastic polymers for friction and wear reduction in highly stressed rolling–sliding contacts. Therefore, hydrogen-containing DLC were deposited polymer surface by a low-temperature high power pulsed magnetron sputtering (HPPMS) physical vapor deposition (PVD) process. rolling-sliding contact ...

Abstract Incorporating dynamic bonds into polymers enables static thermosets to be transformed active materials, possessing the reprocessability of thermoplastics while maintaining bulk properties fully crosslinked networks. This new class termed covalent adaptable networks (CANs), has helped bridge gap between traditional and thermoplastics. Here, epoxy-based were synthesized by combining a di...

Mixed-scale nano- and microfluidic networks were fabricated in thermoplastics using simple and robust methods that did not require the use of sophisticated equipment to produce the nanostructures. High-precision micromilling (HPMM) and photolithography were used to generate mixed-scale molding tools that were subsequently used for producing fluidic networks into thermoplastics such as poly(meth...

Fused deposition modeling (FDM), one among the most commonly used additive manufacturing (AM), techniques has been widely in recent years to produce customized parts with intricate geometries, especially from thermoplastics. This method was limited its ability for industrial applications due inferior properties and poor quality of fabricated parts. Hence, researchers are being driven discover n...

Carbon fiber composites have become popular in aerospace applications because of their lightweight yet strong material properties. The injection molding process can be used to produce discontinuous fiber composites using less time and resources than traditional methods, thereby broadening carbon fiber composites’ applications in different industries. Utilization of longer fibers offers more loa...
