Epoxy resins are widely used in composite materials for aircraft applications. However, they difficult to recycle, thus posing an increasing challenge the aviation sector. By contrast, polyurethane (PUR) can be easily chemically recycled by solvolysis, but structural parts made of carbon fibre-reinforced polyurethanes (CF-PURs) currently not use This is due a lack knowledge about properties CF-...

Structural composite materials with good impact resistance are required in several industrial sectors to design parts submitted crashes or falling objects. This work investigates the behaviour of flax fabrics-epoxy and commingled flax-polypropylene (PP) fibres plates manufactured using compression moulding process. An instrumented drop tower was used conduct low velocity tests at energies high-...

Wroclaw University of Technology, Wroclaw, Poland The paper pr esents r esults of pr eliminary examinations of possibilit y t o measur e binder c ontent in traditional moulding sands using a new method employing electromagnetic waves. The presented examinations were carriedout with use of an innovative test station, the so-called microwave slot line. The meas...

Despite some pitfalls in the practical application of the gas assisted injection moulding (GAIM) process, it offers a number of advantages over conventional injection moulding. However, its inherent complexity requires an advanced control over several additional parameters. This study is preliminar to examine the gas void and its relation to channel geometry and processing conditions for differ...

BACKGROUND During surgery, controlled haemostasis to prevent blood loss is vital for a successful outcome. It can be difficult to ligate vessels located deep in the abdomen. A device that is easy to use and enables secure ligatures could be beneficial. Cable ties made of nylon have been used for ligation but the non-resorbable material caused tissue reactions. The objective of this study was to...

Abstract The mix of two different type fibres, one is natural and another synthetic fibres were employed as reinforcing media in this study, epoxy based polymer resin was the matrix phase. S-glass luffa had been bonded with to create a novel composite by compression moulding measure effect hybridization laminate utilising five sequencing. To determine mechanical characteristics material using t...

Flexible Polyurethane (PU) foam samples with different densities and chemical formulations were tested in quasi-static stress-strain compression tests. The compression tests were performed using the Lloyd LR5K Plus instrument at fixed compression strain rate of 0.033 s-1 and samples were compressed up to 70% compression strains. All foam samples were tested in the foam rise direction and their ...

The objective of this work is to study the influence of the moulding conditions of manufacture on the mechanical behaviour of the composites, when which they are submitted to mechanical loading. In order to evaluate the quality of interfacial adhesion, two non-destructive testing procedures were combined. Laser ultrasonic was employed to evaluate the state of the composite microstructure depend...
