If further testing confirms this, it means that, as the broken bone heals, the glue will disappear naturally. Complex fractures will thus heal more easily.
The results of microscopic observation on the glue line and internal bond testing of the board showed that the condensed water would dilute PF and thus increase its flow and penetration into flakes.
An introduction to the testing method for tensile and shear strength of high strength photosensitive glue is given and the main causes that have influence on the testing result is analyzed.
