Patent ID: 7550186

Claim:
An angle-laminated composite tube, comprising: a plurality of first slices made of a first material, each of the first slices including a fan-shaped inner layer portion and a fan-shaped first interlacing portion, the first interlacing portion being arranged on an outer side of the inner layer portion, and the inner layer portions forming an inner layer of the composite tube; and a plurality of second slices made of a second material different than the first material, each of the second slices including a fan-shaped outer layer portion and a fan-shaped second interlacing portion, the second interlacing portion being arranged on an inner side of the outer layer portion, the outer layer portions of the second slices forming an outer layer of the composite tube, the interlacing portions of the first and second slices forming an interlacing layer of the composite tube; wherein: the first slices and the second slices are angle-laminated alternatively at a specified ply angle relative to the center axis of the composite tube, two adjacent first slices are mismatched by a first mismatching angle along the circumference direction of the composite tube, two adjacent second slices are mismatched by a second mismatching angle along the circumference direction of the composite tube, the interlacing portions of the first slices and the interlacing portions of the respectively adjacent second slices partially overlap with each other, thereby forming the interlacing layer composed of overlapped portions of the first slices and the second slices; and cured thicknesses of the inner layer, the outer layer and the interlacing layer are substantially the same.
