Abstract

The present disclosure provides a carbon fiber dome. The carbon fiber dome includes at least two carbon fiber prepreg layers. The at least two carbon fiber prepreg layers include carbon fiber prepregs made by at least two weaving methods. In addition, the present disclosure provides a method for manufacturing the carbon fiber dome as described above. The method includes the following steps: using prepreg resin to pre-impregnate carbon fiber materials made by at least two weaving methods; and pre-impregnating the carbon fiber materials made by at least two weaving methods for bonding each other.

First claim

What is claimed is:

1. A carbon fiber dome, comprising:
at least three carbon fiber prepreg layers;
wherein
the at least three carbon fiber prepreg layers comprise at least three kinds of carbon fiber prepregs, the three kinds of carbon fiber prepregs comprise uni-directional carbon fiber prepreg tapes and carbon fiber prepreg fabrics and three-directional carbon fiber prepreg tapes;
the carbon fiber dome comprises three carbon fiber layers, with carbon fiber prepreg fabrics used for the uppermost layer, three-directional carbon fiber prepreg tapes used for the middle layer, and uni-directional carbon fiber prepreg tapes used for the lowermost layer.

2. The carbon fiber dome as described in claim 1 , wherein a thickness of the carbon fiber dome is 40˜250 μm.

3. The carbon fiber dome as described in claim 2 , wherein the thickness of the carbon fiber dome is 80˜150 μm.

4. The carbon fiber dome as described in claim 1 , wherein an included angle range of the fibers of the carbon fiber prepreg in adjacent layers is 0 degree 90 degrees.

5. The carbon fiber dome as described in claim 1 , wherein a thickness ratio range of the carbon fiber prepregs in adjacent layers is 1:20˜1:1.

6. The carbon fiber dome as described in claim 1 , wherein the carbon fiber prepregs comprise a carbon fiber material and a prepreg resin, and the tensile modulus of the carbon fiber material is greater than 200 Gpa.

7. The carbon fiber dome as described in claim 6 , wherein the prepreg resin comprises one or more of poly (p-phenylenebenzobisoxazole) and poly-p-phenylene terephalamide.

8. The carbon fiber dome as described in claim 1 , wherein a thickness of the uni-directional carbon fiber prepreg tapes is 60 μm, and a thickness of the carbon fiber prepreg fabrics is 20 μm.

9. A method for manufacturing the carbon fiber dome as described in claim 1 , including the following steps:
using prepreg resin to pre-impregnate carbon fiber materials;
pre-impregnating the carbon fiber materials for bonding each other.

10. The carbon fiber dome as described in claim 1 , wherein the angle between the fiber filaments in the three-directional carbon fiber prepreg tapes is 60 degrees.
