n=S×ρ×m
f/ρ
f
In the formula, n is a carbon fibre initial rinse silk radical;
S is the grid reinforcing rib sectional area;
ρ is the density of carbon fiber enhancement resin base composite material;
m
fBe carbon fiber weight percentage in the carbon fiber enhancement resin base composite material;
ρ
fBe carbon fibre initial rinse silk thread density.
10. according to Claim 8 or 9 described carbon fiber enhancement resin base composite material network part forming methods, it is characterized in that: when each longitudinal grid reinforcement of the described winding of step (2), when the expansion slot that is wound to longitudinal grid reinforcement both ends (10) is located, the carbon fibre initial rinse silk evenly scatters, extends to continuously end frame table face to both sides; Described during at place shop, longitudinal grid reinforcement end covering in step (3), carbon fiber-free weft fabric is a thickening degree shop layer, thereby forms a transition region between grid reinforcing rib (14), covering (15), end frame (4).
