Beschreibung
Zusammenfassung:	A large-size wind power blade with a multi-beam structure and its manufacture method, wherein the blade adopts a hollow layout structure and comprises a blade skin suction edge, a blade skin pressure edge, a main load-carrying structure crossbeam and anti-shearing webs, wherein the blade skin suction edge and the blade skin pressure edge are combined to form a cavity structure having a streamlined cross section, wherein a support structure formed by the combination of the main load-carrying structure crossbeam and the anti-shearing web is located in the cavity. Both the blade skin suction edge and the blade skin pressure edge adopt a multi-segment combined structure, wherein the multiple segments are connected to the side surface of the main load-carrying structure crossbeam to integrally form the blade skin suction edge and the skin pressure edge. Under the premise of ensuring the structural rigidity and strength, the anti-bending capability as well as the stability of the blade of the present invention is increased. With the use of high modulus carbon fiber laxer, the weight of the blade is reduced, the load of the blade, especially the fatigue load, is reduced is reduced.
