Abstract

The invention relates to a box beam composite piece with a metal joint and a manufacturing method thereof. The box beam composite piece with the metal joint comprises two groove-shaped composite beams with lugs, wherein the tail end of each groove-shaped beam is provided with an annular metal end piece; and one part of the end piece is coated in a fiber composite material, and the other part of the end piece is exposed for the combination of upper and lower groove-shaped composite beams. The two groove-shaped beams with the lugs are combined to fixedly form an integrated box beam in modes of bolt fastener locking, gluing or bolt fastener locking and gluing at the laminated protruding lugs and the exposed metal end pieces. The manufacturing method comprises the following steps of: ensuring that the composite material passes through the annular metal end piece on a groove-shaped die with a lug, inversely folding and putting on a groove-shaped composite laminated layer; and curing together at room temperature or a high temperature.

Description

technical field [0001] The invention relates to a box girder composite part containing metal joints and its manufacturing method, in particular to a design and manufacturing method of a composite box girder, which can be applied to the wings of a wind power generator, especially a wind power generator The box girder inside the airfoil, and the box girder is a box girder made of a laminated wing structure with box girder composite materials. Background technique [0002] By the way, in response to the increasing shortage of energy resources today, wind power generation is getting more and more attention, but the most important thing for wind power generation is the wind turbine blades. The reason is that without wind turbine blades, wind power generators cannot Rotation, and the requirements of wind turbine blades are light weight and high structural strength. However, in the existing conventional technology, light weight means weak strength, and high structural strength mean...
