Specific embodiment
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
As shown in Figure 1, a kind of hollow composite pipe, including main pipe body 1 and reinforcing rib 2.Main pipe body 1 is answered by macromolecule
Condensation material is made, and forms hollow structure by production technology, is inside formed with the cavity cooperated for reinforcing rib 2；The number of reinforcing rib 2
Amount is at least one, and above-mentioned reinforcing rib 2 is fixed on the inner wall of main pipe body 1.
Above-mentioned reinforcing rib 2 is the outer wall that composite material is stacked on to reinforcing rib 2 and supporting element in production technology, that is, is reinforced
Muscle 2 cooperates the inner wall in composite material, after thermosetting molding of composite materials, takes out supporting element, reinforcing rib 2 is made to be fixed on composite wood
Expect inner wall, the i.e. inner wall of main pipe body 1.Above-mentioned reinforcing rib 2 can be made of the material for being different from main pipe body 1, have higher
Intensity and fusing point.Above-mentioned reinforcing rib 2 can be made of continuous long carbon fiber or metal wire rod.
According to the needs of intensity, reinforcing rib 2 is there are many fit systems of 1 inner wall of pipe fitting shell, such as: several reinforcing ribs
2 are axially disposed in the inner wall of pipe fitting shell 1；2 helical form of reinforcing rib is arranged in the inner wall of pipe fitting shell 1；Several reinforcing ribs
Transverse and longitudinal is staggered to form mesh arrangement in the inner wall etc. of pipe fitting shell 1.Its fit system passes through the matching in support surface of reinforcing rib 2
Conjunction mode can be realized.
By the way that reinforcing rib 2 is fixed on 1 inner wall of main pipe body, reinforcing rib 2 can connect the inner wall with support tubes main body 1
Structure provides protective effect when 1 stress of main pipe body, to improve the stability of interior wall construction, reinforces the strong of racket
Degree.
A kind of above-mentioned hollow composite pipe can produce to obtain by a kind of method for manufacturing composite pipe, as shown in Fig. 2,
Itself the following steps are included:
Step 1, composite material production: polymer composite is formed into sheet material；
Step 2, inner core production: it pressurizes to fast thawing METAL HEATING PROCESS, makes its liquefaction, and pour into metal core mold, then cool down and make
Its metal core 3 for being solidified into pipe shape, demoulding obtains metal core 3 later, in the fixed reinforcing rib 2 of 3 outer wall of metal core, obtains gold
Belong to cored structure；
Step 3 is arranged air hose: as shown in figure 3, air hose 4 to be set in the outer surface of metallic core means, and being reserved with gas nozzle
Hole；
Step 4 stacks composite material in advance: as shown in figure 4, stacking several layers composite material, shape in above-mentioned 4 outer surface of air hose
At preforming pipe fitting；
