We present the modelling of stimulated Brillouin scattering (SBS) in graded index polymer fibres made with fluoropolymer CYTOPr(Cyclic Transparent Optical Polymer). Comparison of SBS in silica and polymer optical fibres is presented. What emerges is that polymer-based fibre sensors require, compared to silica-fibres sensors, higher power sources (in the order of Watts). The innovative aspect of...

A one step approach to prepare hybrid nanoparticle embedded polymer fibres using pressurised gyration is presented. Two types of novel antimicrobial nanoparticles and poly(methylmethacrylate) polymer were used in this work. X-ray diffraction analysis of the nanoparticles revealed Ag, Cu and W are the main elements present in them. The concentration of the polymer solution and the nanoparticle c...

Fibre-reinforced polymer(FRP), also Fibre-reinforced plastic, is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, or aramid, al‐ though other fibres such as paper or wood or asbestos have been sometimes used. The poly‐ mer is usually an epoxy, vinylester or polyester thermosetting plastic, and phenol formaldehyde resins are still in use...

Progress on microstructured polymer optical fibres (MPOFs), a new class of polymer fibres that were developed last year, will be presented, including various single-mode MPOFs, highly birefringent MPOF, twin-core MPOF, nonlinear MPOF, graded-index MPOF and hollow core MPOF, the latter case being where light is guided in an air core.

Progress on microstructured polymer optical fibres (MPOFs), a new class of polymer fibres that were developed last year, will be presented, including single-mode MPOF, highly birefringent MPOF, twin-core MPOF, graded-index MPOF, ring-structured MPOF and photonic band gap MPOF, the latter case being where light can be guided in an air core.

Electrospinning is a unique way to producing novel polymer nano fibres with diameter typically in the range from 10 nm to 1500nm. Large length to diameter ratio and small mass to volume ratio of these nanosizes fibres widens the areas of their application to many industrial uses. Nylon 6 nanofibres with diameter ranging from 150nm to 1300 nm were produced by the electrospinning process. The fib...

Recently, polymer optical fibre dosimeters have been proposed for use in radiation oncology. Prior to clinical acceptance the effects of radiation on the materials involved must be assessed. In this work, the effects of radiation on mechanical strength and power transmission of polymer optical fibres were investigated. The fibres were subject to high energy electrons and photons generated by a ...

Polymers reinforced with high performance fibres are successfully replacing metal alloys in lightweight aircraft structures. A critical factor in structural design is the resistance of a structure to progressive damage which develops during its service time. The brittle nature of matrix cracking is the main source of composite failure initiating ply delamination and fibre to matrix debonding. B...
