Fig. 2 is the structure enlarged diagram of soft aluminium profiles line in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the present embodiment comprises strengthening core 1 and soft aluminium profiles line 2, and described strengthening core 1 is made up of carbon fiber core composite core rod, and the density of strengthening core 1 is greater than 1.9g/cm
3, tensile strength is 2800MPa-3200MPa.At least one deck soft aluminium profiles line layer is wrapped with at strengthening core 1, in the present embodiment, be wrapped with three layers of soft aluminium profiles line layer at strengthening core 1, every layer of soft aluminium profiles line layer forms by many soft aluminium profiles lines 2 are stranded, and the conductance of described soft aluminium profiles line 2 is more than or equal to 63.5%IACS.The soft aluminium profiles line layer of innermost layer forms by seven soft aluminium profiles lines 2 are stranded, and the soft aluminium profiles line 2 quantity difference that soft aluminium profiles line 2 quantity of every layer is adjacent layer is five.
The cross section of described soft aluminium profiles line 2 is fan-shaped, and this soft aluminium profiles line 2 is minor face 2a near the limit of strengthening core 1, and the limit away from strengthening core 1 is that the transition of long limit 2b, minor face 2a and long limit 2b and two hypotenuses is round-corner transition.
Described soft aluminium profiles line 2 is made up of following steps:
A, melting aluminium, batching is added during melting, the aluminium intermediate alloy ingot that batching is iron, silicon, boron, one or more and fine aluminium in rare earth are alloying component, to ensure that the content adding silicon in the rear aluminium of batching controls 0.03% ~ 0.05%, the content of iron controls 0.05% ~ 0.10%, and iron, silicone content are than the scope being 2.0 ~ 2.2; Guarantee that the content sum of vanadium, titanium, chromium and manganese is not more than 0.001%, the content of copper is not more than 0.001% simultaneously; The content of aluminium is not less than 99.85%, and the temperature of melting furnace is 740 DEG C ~ 750 DEG C;
