Compression after impact of carbon/geopolymer sandwich panels

Popis výsledku v původním jazyce

Geopolymers are amorphous aluminosilicate materials which combine low temperature, polymer-like processing with high temperature stability and fire resistibility without toxic smoke generation. The aim of the paper is to evaluate the impact resistance of the new material. The sandwich panels were manufactured from foam core and carbon fibre/geopolymer skins. Specimens with dimensions of 150 x 100 mm were extracted from the panels. Half of the panels were conditioned in hot/wet environment (70°C/85%r.h.) for two weeks. The drop weight impact tests were carried out in accordance with ASTM D7136M with two levels of impact energy to apply both VID (visible impact damage) and BVID (barely visible impact damage). Then the specimens were loaded by compression according to ASTM D7137M in room temperature conditions. The results showed significant effect of the environmental conditioning on the compression strength. The performance was also affected by the impact damage energy and skin/core adhesive type. During loading, deformation field was measured using a digital image correlation system. This research can establish new fire resistible sandwich materials to be used in aerospace constructions.
