Abstract
The present invention discloses an integrated braiding and needle punching preform forming method, comprising the following steps: arranging gripping devices at both ends of a braiding machine, allowing a mandrel to move in a certain direction along the axis of the braiding machine while forming a first layer of fabric on a surface of the mandrel; then laying felt on top of the first layer of fabric by using an automatic felt laying device, and employing a needle punching device to perform pre-needle punching on the felt layer to ensure the felt adheres to the braided fabric surface; restarting the braiding machine, moving the mandrel in an opposite direction while forming a second layer of fabric on a surface of the felt; repeating the above steps to achieve multiple layers of braided fabric and felt in alternate adhesion; finally, performing main needle punching on the preform.
