The three-dimension integrated hollow sandwich composites is a novel sandwich structure material

which is obtained by interweaving the core material and the upper and lower panels together

and the core material and the panel become a unitary structure. The panel of the three-dimension integrated hollow sandwich composites is integrated with the core material and is formed by one-time curing

so that it has excellent properties such as resistance to delamination

impact resistance

and high damage tolerance. Studying the mechanical properties of three-dimension integrated hollow sandwich composites has important guiding significance for its structural design and application. In this paper

the research progress of mechanical properties of three-dimension integrated hollow sandwich composites in terms of flatwise compression

side compressive

shear

bending and impact properties were introduced in detail

and the existing problems are pointed out

to provide direction for future research.
