Category 2: New applications

Recycled carbon fibre notebook A cover

Exhibitors: Nantong Fuyuan Carbon Fiber Recycling Co., Ltd. and Shenzhen Bromake New Material Co., Ltd.

This recycled carbon fibre notebook A shell product is composed of molded carbon fibre composite boards, and injection molded glass fibre modified polycarbonate (PC) frames. Due to the use of a large amount of recycled materials, including 50% recycled carbon fibre (CF), 100% polypropylene (PP) recycled materials, and 35% PC recycled materials, and the innovative structural design and exquisite molding technology, the excellent mechanical properties and low-carbon emission advantages of recycled CF are ingeniously combined.

This has enabled the developed products to have characteristics such as strong performance, light weight, thin wall and environmental friendliness, and has also opened up a new direction for the commercial application of recycled CF.

Regenerated CF, provided by Nantong Fuyuan, is obtained through pyrolysis and extraction from discarded CFRP high-pressure gas cylinders. It is then made into a regenerated CF surface felt using a paper making process, which is further impregnated with epoxy resin to form a 0.1 t pre-impregnated felt for later use.

Currently, representative products include recycled carbon fibre notebook A shells, which are divided into three categories: sandwich recycled carbon fibre A shells; physical recycled carbon fibre A shells; and plant fibre composite A shells (recycled carbon+plant fibres).

Feiyang, the torch of Beijing 2022 Olympics Winter Games and Paralympics Winter Games

Exhibitor: Sinopec Shanghai Petrochemical Co., Ltd.

Through 3D printing, ceramic molding, and other technologies, the handheld torch shell, made of carbon fibre self-developed by SPC, is more than 20% lighter than the aluminum alloy one. It has the characteristics of “light, solid and beautiful”, which is the international initiative for carbon fibre composite to be used for the Olympic torch.

In the R&D progress, many technical difficulties have been solved, such as high-temperature resistance, combustion resistance, and dimensional stability during the high-temperature preparation process. It has been authenticated that this carbon fibre torch shell with lightweight, high strength could be serviceable in the hydrogen atmosphere under the high combustion temperature.

Multi-wall structure RTM net size aileron

Exhibitor: Jiangsu Hengshen Co., Ltd.

At present, advanced composite materials for aviation are mainly prepared by autoclave processing of prepregs. As it is difficult to achieve the integrated components, riveting and welding might be necessary. While the autoclave itself is so expensive with high energy consumption, making the manufacturing cost accounted for 60% to 70% of the total cost. Based on the characteristics of composite materials, the low-cost integrated manufacturing is an important direction for aviation composite technology.

The composite aileron is integrated manufactured by RTM process. The total length of the aileron is 3,336 mm, with 592 mm in width and 122 mm in height. The integral forming of the parts reduces the use of fasteners, and the use of braided CF tubes forming auxiliary wing wall has greatly improved the pre-preparation efficiency, saving more than 60% of the labor costs.

This technology has been applied to similar structural components such as multi-cavity structure cascades and complex structure fairing skins, with an annual output of more than 200 pieces.
