Abstract: Sandwich structure is widely used in aircraft composite structures, and the mechanical properties of sandwich structures affect the integrity of aircraft structures. The test was carried out using glass fiber board G10-t0.25" embedded in carbon fiber material paper litter of core sandwich panel structure embedded parts, which have different diameters of 20 mm, 30 mm, and 40 mm. The results show that, compared with the typical metal post-embedded structure, the pull-off load is greatly improved. With the increase of embedded part diameter, the load of pull-off increases. However, the load of pull-off does not show significant change when the embedded part diameter is larger than 30 mm.

Key words: composites, sandwich structure, embedded part, glass fibre board, pull-off load
