IMPACT DAMAGE RESEARCH IN COMPOSITE FILAMENT-WOUND TUBES DESIGNED BY ARRAY METHOD
Journal Title: Prace Instytutu Lotnictwa - Year 2016, Vol 244, Issue 3
Abstract
This work presents results of high velocity impact damage in composite filament-wound structures. The subject of research was five-layered composite pipes that have been designed and manufactured in such way as to be able to assess the effect of reinforcement structure – three different mosaic patterns – on the size and nature of impact damage in the composite. The selection of mosaic pattern was based on an array method. It allows to get a lot of mosaic patterns with different rest of the winding stroke and the number of interlaces, which are places of stress concentration and significantly affect the strength of the composite. Impact strength of the composite filament-wound structures was tested in the range of the high velocity impact of 140 ÷ 170 m/s. It is difficult to define which mosaic pattern has the highest impact resistance in the field of high velocity impact.<br/><br/>
