Embodiment Construction

[0041] In conjunction with the drawings, the embodiments of the present invention are described below.

[0042] Please refer first figure 2 Illustrated is a flowchart of an embodiment of a method for manufacturing a composite pipe with a fiber reinforced polymer composite (FRP) interlayer according to the present invention. The steps of this embodiment include:

[0043] In step S10, a first metal embryo tube 21 and a second metal embryo tube 23 are provided. In order to place the second metal embryo tube 23 in the inner diameter 212 of the first metal embryo tube 21 in the following steps, the The outer diameter 232 of the second metal embryo tube 23 must be less than or equal to the inner diameter 212 of the first metal embryo tube 21 (see also image 3 and Figure 4 Shown).

[0044] Step S11, the first metal blank tube 21 is placed in a hydroforming mold 30, and the female mold 31 cavity 311 of the hydroforming mold 30 is closed (please also refer to Figure 5 Schematic diagram o...

Abstract

A tubing with a sandwich layer made of fiber reinforced polymer composite material and a method for manufacturing same. The method comprises the step of providing a first metallic billet pipe, a second metallic billet pipe, of which the outer diameter is smaller than or equal to the inner diameter of the first metallic billet pipe, placing the first metallic billet pipe into a hydraulic forming die, of which the master die hole has a greater die hole outer diameter than the outer diameter of the first metallic billet pipe after the die is closed, swelling the first metallic billet pipe to form a first outer metallic pipe through hydraulic forming method, placing the second metallic billet pipe into the first metallic billet pipe, arranging the fiber reinforced polymer composite material layer on the inner wall of the outer metallic pipe or between the outer surfaces of the second metallic billet pipe, swelling the second metallic billet pipe to form an inner metallic pipe,and demoulding the to take out the composite tubing.

Description

Technical field [0001] The invention relates to a composite pipe fitting and a manufacturing method thereof, in particular to a composite pipe fitting with a fiber reinforced polymer composite material interlayer and a manufacturing method thereof. Background technique [0002] Carbon fiber is a fiber that is lighter in weight than aluminum, stronger than steel, and finer than human hair. Its carbon content is more than 90%. Under the same volume, the weight of carbon fiber is only a quarter of that of iron, even lighter than aluminum alloy, but its strength is four times that of steel. General metal and carbon fiber material composite pipe fittings, especially carbon fiber coated aluminum alloy composite pipe fittings, are often used in bicycle frames. The manufacturing method is mainly manual lamination and fiber winding to layer carbon fiber prepregs. Attached to the aluminum alloy pipe fittings, and then placed in a mold for hot pressing to harden the resin of the carbon fib...
