Preferably, the fiber cloth described to be cut of each group number comprises 4 ~ 9 layers.
Preferably, the long scope of volume of described fiber yardage roll is 100 meters ~ 200 meters.
In the present invention, above-mentioned optimum condition can be combined on the basis meeting this area general knowledge, obtains each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: when the distribution of fiber yardage roll of the present invention and method of cutting out are cut into how many section fibre cloth by each volume fiber yardage roll of designing and calculating, utilization rate is the highest, realize the object of maximum using fiber yardage roll, improve fiber utilization rate, effectively prevent waste, reduce the production cost of fan blade.
Detailed description of the invention
Lift preferred embodiment below, come clearlyer intactly the present invention to be described.
The distribution of fiber yardage roll and a method of cutting out, the method is used for some volume length to be 150 meters fiber cloth involves in row distribution and cutting, and each layer fiber cloth obtained through cutting is for carrying out laying to the girder of a fan blade, and the method comprises the following steps:
Step 101, adds up the length of each layer fiber cloth to be cut, and the level number corresponding to ply stacking-sequence to fiber cloth mark one to be cut described in every one deck, such as, the ground floor fiber cloth of laying during laying is then labeled as 1, and the second layer is labeled as 2, by that analogy.
Step 102, by the fiber cloth grouping described to be cut of variant level number, length sum is made to be divided into one group closest to the some described fiber cloth to be cut that each described fiber yardage roll volume is long, the described fiber cloth to be cut of each group is obtained by fiber yardage roll cutting described in same volume, rolls up on described fiber yardage roll and in fiber cloth to be cut described in every one deck mark corresponding group number respectively at each.Such as, in table 1, the length sum of the 1st, 2,3,36,40 layer of described fiber cloth to be cut is 149.74 meters, closely 150 meters, therefore as fiber cloth to be cut described in same group, and will obtain from cutting fiber yardage roll I respectively; Usually, the fiber cloth described to be cut of each group number comprises 4-9 layer.
Step 103, determines the described fiber yardage roll of the group number corresponding to this level number, according to each described fiber yardage roll of the order cutting of level number, obtains described each layer fiber cloth according to the level number of each described fiber cloth to be cut of mark.
Lower mask body illustrates method of the present invention further for a kind of fan blade, long 68 meters of this kind of fan blade, maximum chord length 5.3 meters, pre-bending 1.8 meters.When manufacturing this kind of fan blade, need to carry out laying respectively to two demifacets of this fan blade main beam, these two demifacets refer to girder windward side (PS face) and girder lee face (SS face).The fiber cloth described girder windward side needing laying 50 layers of length differ, described girder lee face needs the fiber cloth that laying 40 layers of length differ, the concrete length of each fiber cloth to be cut as shown in Table 1 and Table 2.Divide into groups by the fiber cloth to be cut of above-mentioned steps 102 to variant level number, draw group result as shown in table 3, the fiber cloth to be cut of same group number all uses the fiber yardage roll of long 150 meters of the volume of a corresponding group number to carry out cutting.As shown in table 3, the length sum of each fiber cloth group mostly approximates the long size of volume of 150 meters of these fiber yardage rolls, and the fiber cloth of therefore according to said method cutting saves fiber yardage roll very much, and fiber cloth utilization rate is very high.Especially, group number is that after the fiber cloth group of IX is divided into groups by other layer of fiber cloth to be cut, which floor fiber cloth to be cut remaining forms, its length sum is 187.78 meters, closely 190 meters, and volume long size therefore can be adopted especially to be that the volume fiber yardage roll of 190 meters carrys out cutting.
