Within the scope of Collaborative Research Centre SFB 639 "Textile-reinforced composite components for function-integrating multi-material design in complex lightweight applications", woven and flat-knitted spacer fabrics from commingled hybrid yarns are developed, pressed and the characteristics of the formed composite structures are tested. The developed spacer fabric structures have Ushaped ...

Rapid advances in modern electronics place ever-accelerating demands on innovation towards more robust and versatile functional components. In the flexible electronics domain, novel material solutions often involve creative uses of common materials to reduce cost, while maintaining uncompromised performance. Here we combine a commercially available paraffin wax-polyolefin thermoplastic blend (e...

INTRODUCTION Drape of dry fabrics or prepregs was recognised as an important feature in composites forming operations from the start. In the 1950s the first mathematical models were developed based on purely kinematic arguments. The assumption of zero fibre strains and trellis deformations led to the socalled fishnet approach. Typically, these methods require certain arbitrary constraints to re...

The development of highly reliable downhole equipment is an essential element in enabling the widespread utilization of Enhanced Geothermal Systems (EGS). The equipment used in these systems is required to operate at high voltages and temperatures on the order of 200 to 250°C (and eventually to 300 ̊C). These conditions exceed the practical operating ranges of currently available thermoplastic w...

Composite wood products have traditionally relied on thermosetting polymers like phenol-formaldehyde and urea-formaldehyde resins as binders. The continuing need to effectively utilize lignocellulosic fiber from lowquality hardwoods and from recycling streams has prompted consideration of new composites based on thermoplastic polymers [ 1,2]. Much of the development effort has focused on commod...

Objective This study investigated the wear resistance of injection-molded thermoplastic denture base resins using nanoindentation instrument. Materials and methods Six injection-molded thermoplastic denture base resins (two polyamides, two polyesters, one polycarbonate, one polymethylmethacrylate [PMMA]) and a PMMA conventional heat-polymerized denture-based polymer control were tested. Elastic...

This study aimed to evaluate the tensile and transverse bond strength of chairside reline resins (Tokuyama Rebase II, Mild Rebaron LC) to a thermoplastic acrylic resin (Acrytone) used for non metal clasp denture. The results were compared with those of a conventional heat polymerized acrylic resin (Paladent 20) and a thermoplastic polyamide resin (Biotone). The failure sites were examined by sc...
