Abstract
The durability of unidirectional carbon fibre-reinforced epoxy resin composite laminate panels under UV, hygrothermal exposure, and applied tensile stress was investigated experimentally by accelerated ageing tests with determination of interlaminar shear strength via short beam shear testing of conditioned specimens. The data are discussed in comparison with the results of simulations based on a phenomenological predictive model derived using finite element analysis, and in terms of applications in emerging facilities and infrastructure such as bridges and buildings in different climatic zones. 27 refs.

Abstract
The preparation of bacterial cellulose-starch nanocomposites using modified Acetobacter sp. growing medium via a bottom-up technique that allows starch to be introduced into the cellulose network is described. The morphological properties of hot-pressed sheets of the nanocomposites were investigated by ESEM and AFM with data processing by image analysis, and the results are discussed in terms of network properties, such as mesh size and fibre orientation, and the analysis of fracture surfaces. 12 refs.

Abstract
The bond properties of glass fibre-reinforced vinyl ester resin composite dowel bars of circular or elliptical cross-section installed at the transverse joints of concrete slabs were investigated experimentally using draw-out and push-back tests to simulate the repeated shrinkage and expansion movements of the concrete due to temperature and humidity changes. The effects of dowel bar size and shape on pull-out strength are discussed in terms of resistance to destruction of the concrete slabs by curling. 13 refs.

Abstract
The curing of polychloroprene rubber using zinc oxide nanoparticles, synthesised by homogeneous precipitation from zinc nitrate and ammonium carbonate solutions followed by calcination and characterised by TEM, as curing agent was investigated by FTIR, SEM, tensile testing, DMTA and swelling studies. The mechanical and dynamic mechanical properties are discussed in comparison with those obtained using rubber grade zinc oxide in terms of crosslink density and interactions between rubber and curing agent. 28 refs.

Abstract
The fabrication of glass fibre-reinforced composite laminates of ternary reactive blends of novolac epoxy, 2,2'-diallyl-bisphenol A and various proportions of bisphenol A bismaleimide (BMI), and their characterisation after curing by FTIR, DSC, rheological properties, TMA, DMA, flexural, compressive and interlaminar shear strength, fracture toughness, fatigue testing, stress relaxation and fracture surface analysis (SEM), is described. The effects of BMI concentration and of the addition of poly(ethersulphone) as toughening agent on mechanical and high temperature properties of the laminates were investigated and the results are discussed. 26 refs.

Abstract
The synthesis of grafted composite particles by emulsion copolymerisation of styrene with sodium sulphopropyl lauryl maleate and 2-hydroxy-4-(3-methacryloxy-2-hydroxypropoxy)benzophenone with potassium peroxydisulphate as initiator in the presence of titanium dioxide nanoparticles pre-treated with 3-(trimethoxysilyl)propyl methacrylate is described. The products were characterised by UV-visible absorption and diffuse reflectance spectroscopy, weight loss after UV irradiation, DSC and GPC, and the results are discussed in comparison with those for the ternary copolymer itself, for polystyrene and for polystyrene/titanium dioxide composite in terms of resistance to UV irradiation. 16 refs.

Abstract
The commercial development of latent tin mercaptides blocked with organic groups as heat stabilisers for extruded poly(vinyl chloride)(PVC) pipes as a replacement for lead-based stabilisers is described. The stabilisation mechanism and performance attributes including thermal stability under processing conditions, rheology and recyclability of PVC systems containing the heat stabilisers are discussed in comparison with those for lead-containing and alternative commercial calcium-zinc based systems. 11 refs.
