Electrospun fibrous materials have increasing applications in regenerative medicine due to the similarity of fibre constructs to the morphology of certain extracellular matrices. Although experimentally the electrospinning method is relatively simple, at the theoretical level the interactions between process parameters and their influence on the fibre morphology is not yet fully understood. Her...

To compare force levels obtained from glass fibre-reinforced composite (FRC) archwires. Specifically, FRC wires were compared with polymer matrices having different dimethacrylate monomer compositions. FRC material (E-glass provided by Stick Tech Ltd, Turku, Finland) with continuous unidirectional glass fibres and four different types of dimethacrylate monomer compositions for the resin matrix ...

Polymer used in satellite manufacturing are exposed to surface charging phenomenon due electronic irradiations. This can induce electrostatic discharges (ESD) which lead failures. In order limit this phenomenon, we propose develop PEEK composite reinforced with Short Carbon Fibres (SCF). We studied the behaviour of these composites pristine state and after irradiations compared PEEK. state, fib...

Scaling Energy Harvesters In article number 2205563, Peter C. Sherrell, Andris Šutka, and co-workers produce electrospun laminates with controlled internal contact electrification from alternating smooth rough fibres. Bond cleavage polarity ordering create up to 400x the charge compared a typical polymer|polymer device. This approach opens new swathe of applications in vibrational energy harves...

Nano-cellulose materials are widely believed to have the potential to push polymer mechanical properties. The cotton cellulose was dissolved in ionic liquid (1-butyl-3-methylimidazolium chloride ([Bmim]Cl)), and then was isolated by high pressure homogenization in a homogeneous media. The nano-cellulose was obtained at 80 MPa for 30 cycles. The geometry and microstructure of the cellulose nano-...

This talk starts with a review of the different strategies to incorporate nanocarbons (CNTs, graphene) inpolymer matrices and their relative merit in terms of mechanical reinforcement, improvement inelectrical/thermal conductivity and emergence of other functional properties, such as sensingcapabilities [1] [2]. Three types of nanocomposites are discussed: the first type corresponds...

Carbon fibres are a significant volume fraction of modern structural airframes. Embedded into polymer matrices, they provide significant strength and stiffness gains by unit weight compared with competing structural materials. Here we use the Raman G peak to assess the response of carbon fibres to the application of strain, with reference to the response of graphene itself. our data highlight t...
