Carbon fiber prepreg is a composite material made by impregnating carbon fiber fabric or filament with a polymer resin, typically epoxy, which is partially cured or "pre-cured." The prepreg is then used to manufacture carbon fiber reinforced composites with high strength-to-weight ratio and excellent mechanical properties. The processing method of carbon fiber prepreg typically involves the following steps: Fiber selection - Resin impregnation - Partial curing - Cutting and lay-up - Consolidation - Post-curing - Trimming and finishing
Carbon fiber prepreg and carbon fiber cloth are both materials used in the manufacturing of composite materials, but they are not the same materials. Dasen can offer both the two materials for different industries. If you need the materials, please let us know your detailed requirements so that we can choose the suitable material.
Graphite sheets are used to manage heat in aerospace applications. They can be used as heat spreaders or thermal interface materials (TIMs) to efficiently dissipate heat from electronic components, such as avionics systems, sensors, and communication devices. By minimizing temperature fluctuations and hotspots, graphite sheets help improve the reliability and performance of aerospace systems.
In daily wearable devices, graphite also plays a unique role and has significant effects on health physiotherapy. For example, graphite waist protector is composed of an inner liner, a graphite heating film and an outer coating. The thermal energy generated by the carbon atoms in it rapidly heats up within 3 seconds, and can be heated to 20 ℃ to 60 ℃.
It is not only rainy days and nights, but also muggy and high-temperature weather that restrict the efficiency of solar power generation. Therefore, an effective heat dissipation scheme can improve the power generation. Graphite sheets have excellent electrical and thermal conductivity, which can solve the heat dissipation problem and improve the power generation.
In recent years, electronic products are made to be lightweight, thin, short and small. While how to solve the heat dissipation effectively is one of the key factors to evaluate the materials in the case of the constant output power of the products. The heat dissipation paste and thermal conductive tape are only able to achieve 70% efficiency at present. But the graphite heat dissipation sheet can increase the heat dissipation efficiency to nearly 90%.
With the development of automobile industry, more and more advanced technologies begin to be assembled into automobiles, and compact and highly reliable lidar has become an indispensable part. As an unmanned "eye" lidar, the component density and power density are also increasing. Accordingly, the internal heat dissipation of electronic components also puts forward higher requirements. Dasen can offer graphite sheet and thermal pad to meet different requirements.
The thermal interface material can conduct the heat of the inductor to the aluminum housing of the power supply, thereby reducing the inductor temperature. If you choose a hot silicone pad, it has good elasticity and can play a role in shock absorption. Graphite sheets and thermal pads have been successfully and widely used in battery packs of new energy vehicles.
The battery module must be safe, light and compact and suitable for battery electric vehicles and hybrid electric vehicles. Using traditional aluminum heat dissipation will make the battery thick and heavy. While graphite sheet directly replaces aluminum and it can cool the battery during normal charge/discharge operation.
As a new two-dimensional carbon material, graphite sheet has excellent electrical and thermal conductivity. It is the carbon material with the highest thermal conductivity so far. It is very suitable to be used as the heating tube material of household appliances.
5G and Gigabit Internet belong to faster networks, but they need the highest performing thermal interface material (TIM) to maximize their performance. Graphite sheet is a better choice to meet the requirement.
The development of power electronic products in the industrial and consumer fields is very fast. Compared with traditional thermal interface materials (TIM), flexible graphite sheet can provide reliable performance under various conditions and temperatures. It can be die cut to all modules, including WBG devices, inverters and IGBTs.
Taking the urgent demand for thermal design of data processor as an example, the full path high-efficiency heat conduction method based on pyrolytic graphite sheet can reduce the temperature of digital signal processor (DSP) chip by pasting graphite sheet on the computing module frame with concentrated heat source.
We can conduct the heat of heat sources such as chips, Wi-Fi modules, and tuner to the graphite sheet through thermal pad. In the heat dissipation scheme of the devices, graphite sheet is generally attached to the inner side of the shell, and the graphite sheet can quickly reduce the temperature of the heat source.
Wireless charging technology originates from wireless power transmission technology. The utilization of wireless charging technology is increasing. Due to the small volume of the device, the working temperature of the internal electronic components must be solved. Thermal conductive graphite sheet a
For LED/ LED display, uneven heating is a main cause of color aberration and blurred pictures. And these bad pictures may be seen everywhere on the display or even in the corners. For OLED displays, the non-uniform heat can cause uneven aging of the display, resulting in a noticeable color distortio
The thermal processor needs cooling, and the shell’s hot spot must be eliminated. All these must be done by thin and efficient heat-transfer products. With the widest range of ultra-high performance pyrolytic graphite sheets, Dasen have the suitable thermal solutions to meet the performance needs of the industry.
The heat generated by the CPU/Flash chip on the mainboard PCB of the smartphone is evenly transferred to the metal steel bracket and frame in the middle through the graphite film.At this time, the heat of the CPU high-heating chip is quickly averaged to the entire graphite plane. The heat of the ch
Graphite sheets have various applications in the aerospace industry due to their unique properties. Graphite is a lightweight material with excellent thermal conductivity and electrical conductivity. Here are some ways graphite sheets are used in aerospace:
In 2024, JEC Wolrd (France) was held in Paris from March 5th to 7th.
