Influential Factors of Z-pin Bridging Force
Source abstract
Abstract
The nine-pin bridging force experiments are conducted at room temperature (20 °C) and at 75 °C. A three-dimensional z-pin unit cell for finite element analysis is established to study the influential factors of the z-pin bridging force. The experimental results show that the z-pin bridging force at 75 °C is smaller than at 20 °C. The z-pin bridging force is highly dependent on the surface area of z-pin. Therefore, it is feasible that the bridging force can be enhanced by changing the surface area of z-pin. The study also shows that the lay-up sequences of laminates have an impact on the z-pin bridging force, and the maximum bridging force of z-pin rises with the increase elastic modules of the resin. The z-pin bridging force reduces with rise of temperature for two reasons: The elastic modulus and shear strength of the resin decrease with rise of temperature, forcing the bridging force to reduce and the resin makes some clamping effect on z-pin, pushing the bridging force to increase.
