Carbon fiber composite arm rest, method for manufacturing same and concrete pump truck including same

Abstract

The invention discloses a carbon fiber composite arm rest, a method for manufacturing the same and a concrete pump truck including the same. The method for manufacturing the carbon fiber composite arm rest comprises the following steps of: filling air into a contractible airbag to form the airbag with a first status, laying carbon fiber prepreg on the outer surface of the airbag to obtain a firsttransitional component; placing the first transitional component inside a box mold, filling air into the inside of the airbag with the first status, and compressing and shaping the carbon fiber prepreg to obtain a second transitional component; warming and solidifying the second transitional component, and afterwards cooling and demoulding the second transitional component to obtain the carbon fiber arm rest. The method for manufacturing the carbon fiber composite arm rest provided by the invention goes through many times of shaping, so that the carbon fiber prepreg is more compact in structure, which helps to prepare the carbon fiber composite arm rest with excellent performance. Only simple equipments are utilized in the method for manufacturing the carbon fiber arm rest, no autoclave is utilized, so that the equipment cost and production cost are reduced.

Description

technical field [0001] The invention relates to the field of concrete pumping, in particular to a carbon fiber composite boom, a production method thereof and a concrete pump truck comprising the same. Background technique [0002] At present, more and more concrete transportation work is done by concrete pump truck. Concrete pump truck equipment is undergoing a huge change, and is developing in the direction of lightweight and ultra-long. Today, as the design level of concrete pump trucks has become increasingly mature, it is difficult to achieve a huge breakthrough in the lightweight of pump truck products only from the perspective of structural design. [0003] With the deepening of research, technicians found the following deficiencies in traditional pump truck products: [0004] (1) The steel used has a high density and a large weight, making it difficult to reduce the weight of the pump truck; [0005] (2) The traditional steel arm frame is made of tailor-welded hig...

AI Technical Summary

Problems solved by technology

[0004] (1) The steel used has a high density and a large weight, making it difficult to reduce the weight of the pump truck;

[0005] (2) The traditional steel arm frame is made of tailor-welded high-strength steel plates. The welding performance of high-strength steel plates is poor, and due to the poor weldability of high-strength steel plates, cracks are prone to occur at the welds, which shortens the life of the arm frame and easily affects construction. safety;

[0006] (3) The fatigue resistance of traditional high-strength steel is low, and the high-strength steel boom is prone to fatigue fracture, which makes it difficult to meet the requirements of light-weight and ultra-long boom pump trucks;

[0007] (4) The corrosion resistance of the steel arm frame is poor, which further affects the service life of the arm frame

[0011] In the above molding method, the equipment cost and processing cost used are relatively high, which is not conducive to large-scale promotion
