RESEARCH ON THE INFLUENCE OF SECONDARY BONDING VERIFICATION ACCURACYOF COMPLEX HONEYCOMB SANDWICH STRUCTURE

Abstract

Abstract: In view of the secondary bonding process of complex honeycomb sandwich structure, the factors affecting the calibration accuracy are studied by using different verification pressure and verification film combination mode. The results show that the effect of external pressure on the verification accuracy of complex honeycomb sandwich structure is very small at low pressure. The combination method of verification film has a great influence on the verification accuracy. The results of different combination verification films for different areas is better than that of single verification film for different areas. According to the results of the combined verification experiment, the model of verification films selection for the combined verification is established and verified.

Key words: composite, honeycomb sandwich, adhesive bonding, verification
