Highly ordered Z-pin structures |
摘要 |
Improved pin-reinforced sandwich structure ties the face sheets (typically on opposite sides of a foam core) together with a plurality of Z-pins that extend into each face sheet (through the core). The pins are arranged in a tetrahedral or hat section configuration in 2-dimensional or 3-dimensional arrangements to provide enhanced reinforcement, particularly in shear. We are able to improve the pulloff strength additionally by dimpling the core surrounding the pins to produce adhesive fillets along the pins.
