Embodiment Construction
[0031] Further describe the present invention below in conjunction with embodiment and accompanying drawing thereof:
[0032] It is 0.55mm, the coating process of the coated thin rod of 400 order carbon fiber powder that adopt coating method of the present invention to prepare diameter to provide below:
[0033] Thin rod coating process such as figure 1 shown. A bundle of T300-3k carbon fiber enters the resin tank 2 to impregnate the resin, and then enters the initial forming mold 3, the initial forming mold 3, such as figure 2As shown, there is a circular through-hole mold cavity 301 with a length of 7 mm and a diameter of 0.50 mm.
[0034] Thin rod 10 enters in the coating chamber 4 that fills 400 mesh carbon fiber powders immediately after being pulled out from mold 3, and the total stroke (inner cavity length) of uncured thin rod in coating chamber 4 is 300mm, and the drawing of thin rod 10 The pulling speed is 1m / min. The length direction of the coating chamber 4 is ...
