Prepreg carbon fiber is a high-performance material used in many industries, including aerospace, automotive, rail, and transit, owing to its amazing strength and lightweight properties. As a professional composite material manufacturer, Weihai Dushi Composite Materials Co., Ltd. has extensive experience in the production and use of prepreg carbon fiber. Knowing the risks of using the material, we have developed some safety measures for safe use of the prepreg carbon fiber.
Personal Protective Equipment (PPE)
Making sure to wear the appropriate personal protective equipment is the first safety measure when working with prepreg carbon fiber. The material releases small fiber particles when cutting and processing, which can irritate the skin, eyes, and the respiratory system. Therefore, operators must wear dust masks or respirators to prevent the inhalation of harmful particles. There is an additional risk when directly touching the resin on the prepreg carbon fiber. This can cause skin allergies or chemical reactions, so nitrile gloves must be worn. Protective goggles or face shields should be worn to protect eyes from fiber splashes and dust. Weihai Dushi Composite Materials reminds every user that qualified PPE is essential for safe operation and should never be neglected.
When using prepreg carbon fiber, make sure to work in a clean, ventilated workspace to avoid fiber debris and fire risks (plus it’s easier to work in a clean environment!). The resin in prepreg carbon fiber can release VOCs (volatile organic compounds), which are bad for people’s health and the environment. Make sure the workspace includes some ventilation systems or fans to ensure good airflow. Do not keep any unsafe or flammable materials in the workspace, as it may be dangerous to work with the prepreg carbon fiber and other products. Weihai Dushi Composite Materials suggests doing regular inspections and maintenance for ventilation to ensure it works properly.
Cutting and Shaping Safety
To remove and form prepreg carbon fiber, safety precautions must be taken for each individual process. To avoid excess fiber fraying and achieve a more contain cut, use specialized cutting tools such as tungsten or diamond cutters, as recommended by Weihai Dushi Composite Materials. Do not use high speed cutters as they may damage the material and release harmful fumes. If the tools generate a loud noise, wear ear protection as well. Follow the safety guidelines that come with the tools and avoid any misuse that may cause an accident. After cutting, use a vacuum cleaner to remove any fiber debris instead of using compressed air, as this will prevent the spread of harmful particles.
Safety in the Curing Process
Storage and Handling Safety
When curing prepreg carbon fibers you need to follow strict temperature guidelines and safety supervision. Adhere to the time and temperature suggestions provided by Weihai Dushi Composite Materials. Overheating the materials can cause toxic gas to be released and may cause a fire. Make sure your curing equipment is in good condition and has an over temperature protective feature. You should stay with your equipment the whole time and check the equipment regularly. Ensure there is good ventilation in the curing space in case any gas becomes volatile. Wear protective clothing and heat resistant gloves to avoid getting burned when you handle the finished products.
Before use, always prioritize proper storage and handling of prepreg carbon fiber for safety. Store the material in a cool, dry, and well-ventilated place. Avoid direct sun light and high temperature areas. To avoid deterioration of the prepreg carbon fiber, keep it away from oxidizing and corrosive agents. Handle prepeg carbon fiber with care. Do not engage in rough or careless handling that may damage the surface or internal structure of the material. Use lifting devices for heavy rolls to prevent falling injuries. Weihai Dushi Composite Materials cautions users to inspect the seal, packaging, and condition of the material before use and do not use products that are damaged or expired.
Emergency Response Measures
Prepare a list of emergency response actions in the case of accidents involving prepreg carbon fiber. Equip the area with fire extinguishers suitable for fire prevention involving composite materials. If resin comes in contact with skin, wash with plenty of water. If fiber shards get into the eyes, do not rub, instead rinse with clean water for at least 15 minutes, and seek medical assistance if needed. In case of a fire, disconnect the power supply and extinguish it using the suitable fire extinguisher. Weihai Dushi Composite Materials suggests providing safety training for operators, so they know the emergency response actions.
