Effect of peel ply surface treatment on adhesive bonding of polyester and vinyl ester composites used in the maritime industry
Dry peel plies are generally used in composite manufacturing by liquid moulding techniques in the maritime sector. They allow excess resin to bleed through its weaved structure, keeping the surfaces clean, and in certain cases with the required roughness until ready for bonding. However, these plies...

OMAE2017-61519 Tensile Strength of Nylon Netting Subjected to Various Concentrations of Disinfecting Chemicals
This paper presents a study of traditional netting materials subjected to disinfecting chemicals during fish farming and treatment of net cages. A series of tests were performed in order to study the effect of various concentrations of disinfecting chemicals on the tensile strength of Raschel...
Synergy of 3D printing and injection molding: A new prototyping method for rapid design optimization and manufacturing of microfluidic devices
A new rapid prototyping method is reported. It is based on injection molding with inexpensive mold inserts, 3D-printed in durable polymer-based materials. The method allows for manufacturing of microfluidics in common thermoplastics materials at a lower cost and with shorter lead-times compared to...

The role of low temperature impact damage and freeze-thaw exposure on post impact compression strength of glass fibre reinforced polymer-matrix composite materials
An experimental study of the role of sub-zero temperature impact damage and subsequent freeze-thaw exposure on post impact compression strength of quasi-isotropic glass fibre reinforced vinyl ester resin composite materials using non-crimp reinforcements typically applied in the marine industry...
The effect of hydrocarbon ageing on the mechanical properties, apparent crosslink density and CO2 diffusion of a hydrogenated nitrile butadiene rubber (HNBR)
The effect of ageing in a sweet oil environment on the tensile properties, apparent crosslink density, CO2 diffusion and Shore hardness of a typical carbon black reinforced hydrogenated nitrile butadiene rubber (HNBR) is presented. Different ageing conditions yielded materials with different...
Shear Testing of Polypropylene Materials Analysed by Digital Image Correlation and Numerical Simulations
Distributions of shear strains and strain states (triaxiality) were analysed for two in-plane shear test fixtures (Iosipescu and V-notched rail), using digital image correlation and numerical simulations. Three different polypropylene-based materials (two talc-filled compounds and one unfilled...
