The K-cor sandwich construction is a new kind of foam sandwich structure reinforced by Z-pin tech鄄
nique. There are seldom studies available at present. The NHZP-1 resin was used as matrix for partial鄄cured Z-pin爷
s pultrusion processing. 51. 25% of the cure degree is the optimum parameter based on a series of experiments. And
an impending device was made for insertion and flushing for the protruding pin using the two鄄step method. The param鄄
eters of flushing and post鄄cure were also explored. On the basis of the completion, static shear and stretching tests
were conducted under different loads. The pin flattened length is also critical for the configuration. The increased
bonded area between Z-pin and the two skins can enhance the resistance of stretching test behavior
