Industry response to marketing and publicity of the MISG continues to be high with many more than nine projects being identified. Advice and contacts were given to the companies with projects not brought to the MISG week. The following nine topics were considered at the meeting. This project follows on from the analysis of ultrasonic wave propagation at MISG 1994 and focuses on the best way to measure elastic properties of paper as on-line measurements to improve quality control. Amcor have used this design as an extension of an existing patent application and they plan to build and test such a device in their Melbourne labs.
Carbon fibre has exceptional specific strength and stiffness properties desirable in yacht masts.
In normal operation the carbon fibre mast, made with fibres running vertically, can fail under compression when the fibres pop-out of the resin that binds them together. To prevent this failure due to hoop stress, additional fibre is wrapped round the mast. The MISG deduced some mathematical results for the hoop stress of a mast, made up of layers of material, under compression. Finite element analysis gave indications of the percentage fraction of carbon fibre that must be used to match hoop stress. A literature search revealed that stress concentrations are reduced if the fibres are laid at an angle of 55 degrees 44 minutes.
