摘要近几十年来，复合材料发展迅速。在航空航天、军事、船舶和建筑等领域所占的比重越来越大。而无人艇复合材料纤维铺放系统是碳纤维增强塑料的先进制造装备之一, 它适于加工外形复杂的构件。纤维铺放头机构在本文设计的装备中是一个关键机构。本课题针对船舶中的高性能碳纤维无人小艇的制造，提出一个设计方案，实现碳纤维铺放的加料、施压、剪切、加热等功能 。51997

为了实现上述的功能，本文拟定的通过类似龙门的方式实现纤维铺放装置在X、Y、Z轴方向的运动，满足了小船模型曲面铺放纤维的需求。通过气缸带动铰链机构实现切刀和压头的操作，完成纤维的剪切和夹紧的过程。通过电机带动的齿轮和送料辊的方法来完成纤维的重送。同样，在气缸和压辊的作用下，可以实现纤维在模具表面的压力，从而达到利用气缸来调整给定压力的目的。本文设计的铺放机研制展现了对完成夹紧、剪切及重送方面的功能，证明了此装置的可行性。

Abstract

In recent decades, the rapid development of composite materials. In the aerospace, military, marine and construction and other fields the proportion is growing. The unmanned boat composite fiber placement system is a carbon fiber reinforced plastics (CFRP) is one of the advanced manufacturing equipment, it is suitable for processing complex shape components. Fiber placement head is the key institutions of the equipment of this topic for the ship in the high-performance carbon fibers manufactured unmanned boats propose a design scheme to achieve carbon fiber placement of feeding, pressing, cutting, heating and other functions . 

To achieve the above functions, the paper proposed a similar way to achieve the goal-fiber placement apparatus X, Y, Z axis direction movement, to meet the needs of the mold surface. Hinge mechanism driven by the air cylinder to achieve the operation of the cutter head and the complete fiber cut and clamping process. Through the motor driven feed roller gear and methods to accomplish the fiber resend. Similarly, the cylinder and the pressure roller under the effect of the fiber can be achieved in the mold surface of the pressure, so as to adjust the air cylinder to achieve a given pressure purposes. This design shows the placement machine developed for complete clamping, cutting and re-delivery aspects of the function, proved the feasibility of this device.
