The impact of wear on mechanical properties of roving
IOP PUBLISHING LTD, DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND
The paper deals with the influence of mechanical wear out on the resulting mechanical properties of roving. The paper deals with the scraping of roving from inorganic fibres. Glass, carbon and basalt roving are used for this experiment. Rovings are mainly used for the production of composites. The preparation of the roving for processing into composites includes their coiling of the supplied large coils on the coils used in the manufacture. With this rewinding, mechanical damage to roving can occur, which could result in loss of strength. The aim of this work is to determine whether the values of the mechanical properties change depending on the wound generated during winding. For this purpose, a special Cycle Abrasion Apparatus has been developed to simulate wiping during winding. The work is first aimed at finding the optimal measurement procedure on the Abrasion Apparatus. Further, the results of weight loss, loss of strength, particle removal and measurements on the Zweigle G522 instrument are processed.
