Bond strength and performance of optical fibre Bragg gratings sensors embedded in composite patch repairs for military aircraft
Jones, Tyler Paul; Thorvaldsen, Tom; Sagvolden, Geir; Pran, Karianne; Olsen, Torbjørn (2016)Structural health monitoring (SHM) systems are recognized as a key element in a modern and efficient approach to structural lifecycle management. With novel applications of advanced materials, such as extensive use of ... -
Investigation of Theoretical Models for the Elastic Stiffness of Nanoparticle-Modified Polymer Composites
Thorvaldsen, Tom; Johnsen, Bernt Brønmo; Olsen, Torbjørn; Hansen, Finn Knut (2015)Mathematical models are investigated and suggested for the calculation of the elastic stiffness of polymer nanocomposites. Particular emphasis is placed on the effect on the elastic stiffness from agglomerates and the ... -
Micro indentation hardness testing of commercial-grade RDX crystals
Moxnes, John Fredrik; Frøyland, Øyvind; Olsen, Torbjørn; Jensen, Tomas Lunde; Unneberg, Erik (2016)This paper describes the continuous micro indentation hardness testing of two commercial grades of RDX with differing shock sensitivities using three (3) different loads on a Berkovich indenter to obtain values of elastic ... -
The Optimum Dispersion of Carbon Nanotubes for Epoxy Nanocomposites: Evolution of the Particle Size Distribution by Ultrasonic Treatment
Frømyr, Tomas Roll; Hansen, Finn Knut; Olsen, Torbjørn (2012)The ultrasonic dispersion of multiwalled carbon nanotube (MWCNT) suspensions was assessed by studying the differential sedimentation of the particles in an acid anhydride often employed as a curing agent for epoxy resins. ... -
Preparation and characterisation of epoxy/alumina polymer nanocomposites
Johnsen, Bernt Brønmo; Frømyr, Tomas Roll; Thorvaldsen, Tom; Olsen, Torbjørn (2013)The effect of adding nanosized alumina fillers of both fibre-like and spherical shapes to an epoxy polymer has been investigated. The alumina was dispersed in the epoxy hardener using two different sonication techniques. ...
