Glass-fibre reinforced polymer matrix composites exhibit superior properties to traditional materials. Thus, they have found a broad variety of applications in modern industry. For process development and quality control sophisticated three-dimensional methods for non-destructive characterization are needed. X-ray computed tomography (CT) is a powerful radiographic nondestructive-testing method...

In this work, polyamide 11 (PA11) and stone ground wood fibres (SGW) were used, as an alternative to non-bio-based polymer matrices and reinforcements, to obtain short fibre reinforced composites. The impact of the reinforcement on the thermal degradation, thermal transitions and microstructure of PA11-based composites were studied. Natural fibres have lower degradation temperatures than PA11, ...

Fibre materials span a broad range of applications ranging from simple textile yarns to complex modern fibre-optic communication systems. Throughout their history, a key premise has remained essentially unchanged: fibres are static devices, incapable of controllably changing their properties over a wide range of frequencies. A number of approaches to realizing time-dependent variations in fibre...

The mechanism of toxicity of selected asbestos substitute mineral fibres was examined and compared to that of asbestos. Alveolar macrophages and type II cells were isolated from Fischer 344 rats and after 20 h cultivation various concentration of fibres alone (amosite, wollastonite, rockwool or glass fibres) or in combination with cigarette smoke were added to cells and the cultivation continue...

The microstructure and thermomechanical behaviour of a novel fully biodegradable polyvinyl alcohol (PVOH)-based single-polymer composite (SPC) is presented. Three kinds of PVOH stapled fibres, having different melting temperatures and tensile mechanical properties, were considered as a reinforcement, whilst plasticized PVOH granules were selected as a continuous matrix. Calorimetric tests on th...

As flax fibres exhibit good mechanical properties and low cost, they are more and more considered, since the early 2000’s, as efficient reinforcement for polymer based composites in replacement of E-glass fibres in automotive or building areas. The properties of the elementary fibres are now relatively well-known (strength comprised between 600 and 2000 MPa, Young’s modulus around 50 GPa and fa...

A rapid method has been developed for measuring the binding capacity of asbestos and other mineral fibres for environmental carcinogens. Benzo(alpha)pyrene (B(alpha)P), nitrosonornicotine (NNN), and N-acetyl-2-aminofluorene (NAAF) were assayed in the presence of Canadian grade 4T30 chrysotile, chrysotile A, amosite, crocidolite, glass microfibres, glasswool, attapulgite, and titanium dioxide. C...
