Embodiment 1
[0044] 1) Twisting two bundles of 6k carbon fibers into a carbon fiber rope with a twist of 200 twists / m; then weaving 24 twisted carbon fiber ropes into a strip-shaped continuous carbon fiber braid. The area density is 30g / m2 by needle needle 2 The carbon fiber nonwoven fabric is riveted on the continuous carbon fiber braid, and the riveting point density is 10 points / cm 2 , to obtain the prefabricated body of carbon fiber sternum slice. Weave 2 bundles of 6k carbon fiber twisted ropes with a twist of 200 twists / m, and 10 twisted carbon fiber ropes into a strip to obtain a prefabricated carbon fiber clavicle strip. Two bundles of 6k carbon fiber twisted ropes with a twist of 200 twists / m are braided into strips, and then spirally wound into a spring through a rod-shaped carbon material mold with one coil to obtain a carbon fiber joint prefabricated body. Extend the carbon fiber at both ends of the joint prefabricated body into the carbon fiber at the connecting end of the c...
Embodiment 2
[0053] 1) Twisting 3 bundles of 12k carbon fibers into a carbon fiber rope with a twist of 300 twists / m; then weaving 12 twisted carbon fiber ropes into a strip-shaped continuous carbon fiber braid. The area density is 20g / m2 by needle needle 2 The carbon fiber non-woven fabric is riveted on both surfaces of the continuous carbon fiber braid to form a sandwich structure, and the riveting point density is 10 points / cm 2 , to obtain the prefabricated body of carbon fiber sternum slice. Three bundles of 12k carbon fiber twisted ropes with a twist of 500 twists / m were braided into a strip to obtain a prefabricated carbon fiber clavicle strip. Three bundles of 12k carbon fiber twisted ropes with a twist of 200 twists / m were braided into a strip, and then spirally wound into a spring through a rod-shaped carbon material mold with 2 coils to obtain a carbon fiber joint prefabricated body. Extend the carbon fiber at both ends of the joint prefabricated body into the carbon fiber at ...
Embodiment 3
[0062] 1) Twisting two bundles of 24k carbon fibers into a carbon fiber rope with a twist of 100 twists / m; then weaving 12 twisted carbon fiber ropes into a strip-shaped continuous carbon fiber braid. The area density is 25g / m2 by needle needle 2 The carbon fiber non-woven fabric is riveted on the two surfaces of the continuous carbon fiber braid to form a sandwich structure, and the riveting point density is 12 points / cm 2 , to obtain the prefabricated body of carbon fiber sternum slice. Two bundles of 24k carbon fiber twisted ropes with a twist of 100 twists / m were braided into a strip to obtain a prefabricated carbon fiber clavicle strip. Two bundles of 24k carbon fiber twisted ropes with a twist of 100 twists / m are braided into strips, and then spirally wound into a spring through a rod-shaped carbon material mold with 2 coils to obtain a carbon fiber joint prefabricated body. Extend the carbon fiber at both ends of the joint prefabricated body into the carbon fiber at t...
