Embodiment 1
[0097] Example 1: Quasi-isotropic interweave ply laminate (m=4, k=2, p=0)
[0098] Such as figure 1 As shown, the specific steps are as follows:
[0099] 1) Select flat mold and carbon fiber epoxy resin prepreg tape;
[0100] 2) Complete the laying of one prepreg tape in one belt at intervals of 45°, so as to cover the entire plane;
[0101] 3) Complete the laying of one prepreg tape at intervals of 90°, so as to cover the entire plane;
[0102] 4) Complete the laying of one prepreg tape at intervals of one belt at -45°, so as to cover the entire plane;
[0103] 5) Complete the laying of one prepreg tape at intervals of 0°, so as to cover the entire plane;
[0104] 6) Use the prepreg tape to cover the 45° prepreg tape for the interval bandwidth in step 2), so as to cover the entire plane;
[0105] 7) Use prepreg tape to cover the interval bandwidth of step 3) with 90° prepreg tape, so as to cover the entire plane;
[0106] 8) Use prepreg tape to cover the width of the in...
Embodiment 2
[0115] Embodiment 2: 2.5-dimensional laminated ring structure interwoven between asymmetric layers (m=3, k=2, p=1)
[0116] 1) Select the ring mold and carbon fiber epoxy resin prepreg tape;
[0117] 2) Complete laying of 1 prepreg tape with 1 width interval at 60° intervals, so as to cover the entire cylinder, recorded as 60 A ,Such as figure 2 shown;
[0118] 3) Lay one prepreg tape at intervals of one belt at -60°, so that the entire cylinder is covered, and it is recorded as -60 A ,Such as image 3 shown;
[0119] 4) Complete the laying of 1 prepreg tape at 0° intervals and 1 belt, so that the entire cylinder is covered, and it is recorded as 0 A ,Such as Figure 4 shown;
[0120] 5) Use prepreg tape to cover the width of the interval in step 2) with 60° prepreg tape, so that the entire cylinder is covered, and it is recorded as 60° B ,Such as Figure 5 shown;
[0121] 6) Use prepreg tape to cover the width of the interval in step 3) to -60° prepreg tape, so tha...
Embodiment 3
[0131] Embodiment 3: Interwoven 2.5-dimensional structure laminated board between symmetrical layers (m=3, k=2, p=1)
[0132] 1) Select flat mold and carbon fiber epoxy resin prepreg tape;
[0133] 2) With reference to the laying method of Example 2, complete an asymmetric interwoven laminate of a certain thickness, and the laying sequence is:
[0134] [±60 A / 0 A ][±60 B / 60 A / 0 B / -60 A / 0 A ] n-1 [±60 B ];
[0135] 3) Complete laying of 1 prepreg tape at intervals of 90°, so as to cover the entire plane, recorded as 90 A ;
[0136] 4) complete 0 B layer laying;
[0137] 5) Use prepreg tape to cover the width of the interval in step 4) with 90° prepreg tape, so that the entire plane is covered, and it is recorded as 90° B ;
[0138] 6) Follow step 2) to complete the laying of the symmetrical part of the interwoven ply board according to the mirrored ply sequence. The total ply sequence is:
[0139]
[0140] In this example n=4, the thickness of the part i...
