Original Abstract

The fracture resistance to the dynamic loading of composites based on partially pyrolysed SiOC glass reinforced with basalt fibres was investigated using an instrumented impact test. The three-point bend loading configuration of the specimen bars prepared from the composite plate was used. Evolution of the matrix during the pyrolysis plays a key role in creation of bonding between the matrix and fibres, which was in the form of woven fabrics. Different temperatures of pyrolysis were applied in order to determine their influence on the fracture behaviour during impact tests. The high speed camera was employed to observe fracture response to impact loading during the fracture process. The temperature range for pyrolysis was chosen from 600 to 800C with the step of 50C. The partial melting of basalt fibres occurred at temperatures above 800C. Observation of fractographic features on the fracture surfaces was performed using scanning electron microscopy.
