The relationship between heat release rate and other fire reaction properties of fibre reinforced polymer composite materials is investigated. The heat release rate and fire reaction properties of thermoset matrix composites reinforced with combustible fibres (aramid, extended-chain polyethylene) or non-combustible fibres (glass, carbon) were determined over a range of heat flux levels using th...

Like any other laser, a fibre laser consists of an active medium (in this case a piece of doped optical fibre) between two feedback elements. While Fresnel reflection from the fibre end facet can assume the role of a broadband partially reflecting output coupler, fibre Bragg gratings (FBGs) are an obvious choice for the implementation of a frequency selective high reflector in an all-fibre desi...

Thermo-set based composites using epoxy resin systems currently dominate the composite industry. Glass-reinforced epoxy composites are extensively used in the structural composites of aircraft industry due to low shrinkage, ease of fabrication, chemical resistance, and higher mechanical and electrical properties. The above characteristics coupled with techno-economic considerations are mainly r...

The evolution of particles, during the fabrication step particle-containing glass fibres, was investigated. aim this study to characterize quantitatively composition, size and shape distribution Mg-silicate particles within initial silica-based preform final fibre, these information being crucial better understand mechanisms involved drawing step. A combined experimental approach using Scanning...

The growth mechanism of Atomic Layer Deposition (ALD) on polymeric surfaces differs from inorganic solid substrates, such as silicon wafer or glass. In this paper, we report the experiments Al2O3 and ZnO nonwoven poly-L-lactic acid (PLLA), polyethersulphone (PES) cellulose acetate (CA) fibres. Material in both ALD infiltration mode was studied. structures were examined with a scanning electron ...

BACKGROUND Man-made vitreous fibres (MMVFs) are used in products for insulation and as reinforcement in materials. Contamination of the skin may arise through direct or indirect contact, and from the deposition of airborne fibres. The scientific basis regarding the effects on skin of MMVFs dates from 1970-1980. OBJECTIVES To investigate whether currently used insulation MMVF products still ca...

Inspired by the adhesion mechanisms of several animal species such as geckos, beetles and flies, several efforts in designing and fabricating surface engineering strategies have been made recently to mimic the adhesive and frictional behaviour of biological foot pads. An important feature of such biological adhesion systems is the ability to switch between strong attachment and easy detachment,...
