The original version of this article unfortunately contained mistakes. Below is a list of corrections. The red color font is the final correct text after the modification. Several images in the article that need to be changed are already marked below.

1. Table 3 was incorrect in the Original Paper. The corrected Table 3 is given next page:

Table 3 Surface figures of simulated composite space mirrors with varied layup sequences

2. Figure 1 was incorrect. The corrected Figure 1 is given below:

3. Figure 2 was incorrect. The corrected Figure 2 is given below:

4. In the second line of the eighth paragraph of Section 4.2 (page 11):

“We can found that, the surface PV values of composite mirrors decrease with the increase of number of symmetric sequences in the case of one angular deviation in the stacking sequences, and so the surface precision of composite mirrors get improved.” was changed to “We can found that, the surface PV values of composite mirrors decrease firstly and then increase with the increase of number of symmetric sequences in the case of one angular deviation in the stacking sequences.”

5. In the fifth line of the eighth paragraph of Section 4.2 (page 12):

“Comparing with angular increments reduction, adding number of symmetric sequences can obviously improve bending stiffness and surface precision of composite mirrors.” was changed to “Comparing with angular increments reduction, adding number of symmetric sequences properly can obviously improve bending stiffness and surface precision of composite mirrors, but increasing the number of symmetric sequences excessively cannot further enhance the bending stiffness of composite mirrors.”

6. In the sixth line of the tenth paragraph of Section 4.2 (page 12):

“Increasing number of symmetric sequence plays an obvious role in improving surface figures of composite mirror,” was changed to “Increasing number of symmetric sequence properly plays an obvious role in improving surface figures of composite mirror,”

7. Figure 3 was incorrect. The corrected Figure 3 is given below:

8. Table 5 was incorrect in the Original Paper. The corrected Table 5 is given below:

Table 5 Surface figures of composite space mirrors for the six typical layup sequences with the angular deviations on the first ply

9. Figure 4 was incorrect. The corrected Figure 4 is given below:

10. Figure 5 was incorrect. The corrected Figure 5 is given below:

11. Figure 6 was incorrect. The corrected Figure 6 is given below:

12. Table 6 was incorrect in the Original Paper. The corrected Table 6 is given below:

Table 6 Characteristic values of surface figures of composite space mirrors for six typical layup sequences with random angular deviations

13 In the fifthteenth paragraph of Section 5.2 (page 18):

“Median and minimum of surface PV values for layup sequence 05 are the lowest, and so the surface accuracy of composite mirror placed with layup sequence 05 is relative best here.” was changed to “Third quartile and minimum of surface PV values for layup sequence 05 are the lowest, while first quartile and median of surface PV values for layup sequence 06 are the lowest. Compared to layup sequence 06, composite mirrors placed with layup sequence 05 are less affected by random angular deviation, and so the surface accuracy of composite mirrors placed with layup sequence 05 is relative best here.”

14 In the second line of item no.2 of the Conclusions section (page 19):

“To further improve surface precision of composite mirror, increasing number of symmetric sequence plays an obvious role in improving surface figures of mirror” was changed to “To further improve surface precision of composite mirror, increasing number of symmetric sequence properly plays an obvious role in improving surface figures of mirror”
