I. Key Components of Agricultural Machinery

Carbon fiber agricultural machinery frame and body

Characteristic advantages: The specific strength (the ratio of strength to density) of carbon fiber composite materials is 4 to 5 times that of steel. When used to manufacture the frames or bodies of agricultural machinery such as tractors and harvesters, it can reduce the overall weight of the machine by 15% to 30% while ensuring structural strength. For instance, the cab frames of some high-end agricultural machinery are made of carbon fiber, which not only reduces fuel consumption but also enhances the mobility of the equipment in complex terrains.

Application case: The bodies of some agricultural robots in Japan are made of carbon fiber composite materials, combined with lightweight design, making them more suitable for operation in narrow Spaces such as greenhouses and orchards, while reducing soil compaction.

2. Carbon fiber transmission components

Drive shafts and gears: Carbon fiber drive shafts have excellent damping performance, which can reduce vibration and noise during the transmission process. They also have strong fatigue resistance, and their service life is 2 to 3 times longer than that of metal drive shafts. For instance, if the drive shaft of a large combine harvester is made of carbon fiber, it can reduce maintenance frequency and enhance operational efficiency.

Pulleys and bearings: The wear resistance and corrosion resistance of carbon fiber composite materials make them suitable for damp and dusty agricultural environments. For instance, after the pulley of a rice harvester is made of carbon fiber, it can prevent metal parts from rusting due to long-term contact with mud and water, and reduce the phenomenon of belt slippage.

3. Carbon fiber harvesting and tillage components

Cutting blade: The lawn mower blade made of carbon fiber reinforced ceramic matrix composite material is of high hardness and light weight. Its cutting efficiency is over 10% higher than that of traditional steel blades, while reducing equipment energy consumption.

Ploughshare: The surface of the carbon fiber ploughshare can be coated with a wear-resistant layer. When working in heavy clay soil, its resistance is 15% lower than that of metal ploughshares, and it is less likely to adhere to soil, reducing cleaning costs.

Ii. Planting and Breeding facilities

Carbon fiber greenhouse frame

Structural advantages: Carbon fiber tubes have high strength and good toughness. They are used to build the framework of greenhouse sheds and can withstand strong winds (up to 12-level typhoons) and heavy snow (snow load up to 0.5kN/㎡). Moreover, they are 40% lighter than aluminum alloy frameworks, making them convenient for transportation and installation.

Weather resistance: Carbon fiber composite materials do not react with acids or alkalis. They are not prone to corrosion in high-humidity and high-salt spray environments (such as coastal areas), and their service life can reach over 20 years, which is 2 to 3 times that of traditional steel frames.

Application case: Some modern greenhouses in the Netherlands are equipped with carbon fiber frames and transparent photovoltaic panels, which not only meet the light requirements of plants but also generate electricity for self-sufficiency, achieving an integration of “planting + energy”.

2. Carbon fiber aquaculture cages and fences

Marine aquaculture: The carbon fiber cage frame is resistant to salt spray corrosion in seawater and is 60% lighter than the steel frame, making it convenient for ships to tow and move. For instance, the deep-sea salmon farming cages in Norway are made of carbon fiber composite materials, which can resist the impact of strong waves, reduce the attachment of Marine organisms (with a high surface smoothness), and lower the cleaning cost.

Freshwater aquaculture: Carbon fiber fences are used in fish ponds or shrimp ponds. They can prevent metal from rusting and polluting water quality, and have high strength, which can resist the impact of fish or damage from wild animals.

3. Carbon fiber irrigation components

Water delivery pipes: The inner wall of carbon fiber composite pipes is smooth, and the water flow resistance is 20% lower than that of PVC pipes, which can reduce the energy consumption of irrigation pumps. In addition, its high-pressure resistance (working pressure up to 1.6MPa) makes it suitable for drip irrigation, sprinkler irrigation and other systems, especially in mountainous areas or regions with complex terrain, which can reduce the risk of pipeline rupture.

Nozzle bracket: The carbon fiber nozzle bracket is lightweight and can be installed on drones or mobile irrigation vehicles. It can flexibly adjust the spraying Angle while reducing the load on the equipment.

Iii. Agricultural Tools and Consumables

Carbon fiber farm tools

Handheld tools: carbon fiber hoes, sickles, garden shears and other tools are over 50% lighter than metal tools. Long-term use can reduce the labor intensity of farmers. For instance, the carbon fiber garden scissors launched by Japan have a blade made of carbon fiber reinforced silicon carbide material, and their sharpness retention time is three times that of steel scissors.

Backpack equipment: Carbon fiber backpack frames are used for backpack sprayers, lawn mowers, etc. They are light in weight and high in strength, which can distribute the weight of the equipment and reduce the fatigue of farmers’ shoulders.

2. Carbon fiber seedling raising and planting auxiliary tools

Seedling trays: Carbon fiber seedling trays have excellent thermal conductivity and air permeability, which can promote the root development of seedlings. They are also resistant to mold corrosion and can be reused more than 50 times (traditional plastic trays can only be reused 10-15 times).

Plant support frame: Carbon fiber rods are used to support vine plants such as grapes and tomatoes. They are strong and not prone to aging, and can replace bamboo poles or metal frames, reducing the annual replacement cost.

3. Carbon fiber agricultural drone components

The frame of the fuselage: The agricultural drone adopts a carbon fiber fuselage, which is light in weight (the overall weight can be controlled within 5kg) and has strong shock resistance, making it suitable for low-altitude plant protection operations. For instance, the arms and landing gear of DJI’s T series agricultural drones are made of carbon fiber composite materials, which extend their endurance by 15 minutes compared to traditional plastic fuselages.

Spraying system bracket: The carbon fiber bracket can fix the pesticide box and the nozzle, reduce vibration during flight, and improve spraying accuracy (error less than 5cm).
