Carbon-fibre composite boom for concrete pump truck

The invention relates to a carbon-fibre composite boom for a concrete pump truck, belonging to the field of composites. A main body box girder is arranged, wherein a 90-degree angled carbon fiber cloth pre-impregnation material is laid on the inner layer of the main body box girder, and a 45-degree angled carbon fiber cloth pre-impregnation material is laid on the middle layer of the main body box girder, and a 0-degree angled carbon fiber cloth pre-impregnation material is laid on the outer layer of the main body box girder; the root of the main body box girder is provided with a plywood connected in an integrated way. The beneficial effects of the invention are as follows: the carbon-fibre composite boom gives full play of the higher specific strength, bigger specific modulus, fatigue resistance and corrosion resistance of the carbon-fibre reinforced epoxy resin composite so as to obtain a boom of a pump truck with excellent performances and reduce weight of the boom by 40-60%. At the same time, the carbon-
