Abstract Fusion assembly is a highly promising technique for joining thermoplastic composite to thermoset composites, enabling the use of both most affordable material and process each substructure. However, some major challenges need be addressed such as functionalizing surface through co-curing with an appropriate interlayer or realizing fast robust welding that meets all quality mechanical r...

This study aims at assessing the sensitivity of ultrasonic welding process for joining epoxy- to thermoplastic-based composites heating time. For that, carbon fibre (CF)/epoxy adherends with a co-cured PEI coupling layer were ultrasonically welded CF/polyetheretherketone (PEEK) different times. Process-induced changes in meso and microstructure these welds identified correlated weld strength. S...

Abstract Tribological applications of polytetrafluoroethylene (PTFE) are often limited by technological complexity to overcome its poor wear resistance. Here, a PTFE/polyetheretherketone (PEEK) heterolayer (HL) was proposed and evaluated as new solid lubrication solution. Pin-on-disk tribometry found the lowest friction coefficient ( μ ) 0.031 ultralow for PEEK/HL under typical conditions. The ...

Removable partial dentures are still widely used to repair dental defects. Due the problems of aesthetic defects, heavy weight, and metallic odor metal removable that in clinical practice, non-metallic alternative materials now actively explored. As a new material with good physical chemical properties, polyether ether ketone (PEEK) has been tried be fabrication dentures. In this paper, we revi...

Cranioencephalic traumatism (TBI) is a common situation in trauma hospitals and has become responsible for high rates of mortality worldwide. When the victim TBI affected by injuries to skullcap with need grafting, problems regarding availability suitable affordable materials eventually happen. In this study, 3D structure Polyetheretherketone (PEEK) that mimics cranial bone morphology use crani...

Helical Auxetic Yarns (HAYs) can be used in a variety of applications from healthcare to blast and impact resistance. This work focuses on the effect use different core materials (e.g. rubber, polyurethane, polytetrafluoroethylene/teflon, polypropylene, polyetheretherketone, polycarbonate, acetal) with nitinol wire wrap component maximum Negative Poisson Ratio (NPR) produced thus auxetic perfor...
