Manufacturing method for unmanned aerial vehicle non-equal-diameter closed square pipe shaped carbon fiber beam

Abstract

The invention provides a manufacturing method for an unmanned aerial vehicle non-equal-diameter closed square pipe shaped carbon fiber beam so as to effectively solve the technical problems that an existing manufacturing method for the unmanned aerial vehicle non-equal-diameter closed square pipe shaped carbon fiber beam is narrow in application range, demolding is difficult, the airbag core filmyield is low, the service life is short, the flow is complicated, and the cost is relatively high. The manufacturing method for the unmanned aerial vehicle non-equal-diameter closed square pipe shapedcarbon fiber beam comprises the following steps that 1) an upper female die and a lower female die are machined; 2) an upper beam is machined by using the upper female die; 3) a lower beam is machined by using the lower female die; 4) the upper beam and the lower beam are bonded by using a bonding combining tool; and 5) the bonding combining tool is removed to obtain the required non-equal-diameter closed square pipe shaped carbon fiber beam. According to the manufacturing method, an integral component is divided into two parts to be separately formed, compared with integral forming, the requirements on a forming process and a forming tool are relatively low, and the problem of difficult demolding of the non-equal-diameter closed square pipe beam is solved.

Description

technical field [0001] The invention relates to a method for manufacturing a carbon fiber beam for an unmanned aerial vehicle, in particular to a method for manufacturing a non-equal diameter closed square tubular carbon fiber beam for an unmanned aerial vehicle. Background technique [0002] With the development of UAVs, the shape of UAVs is changing with each passing day, and the structural forms of UAV beams are also various. Among them, the non-equal-diameter closed square tubular carbon fiber beam has a better fit than the equal-diameter square tubular carbon fiber beam. The advantages of unmanned vehicle type and superior load-bearing performance. At present, non-equal-diameter closed square tubular carbon fiber beams are mostly manufactured as integral components, and there are generally disadvantages such as difficult demoulding, high production costs, complicated processing, and long processing cycles during molding, and have high requirements on the molding process...
