Automotive lightweighting is also a market trend for basalt fibers

Experiments have proved that for every 10% reduction in the weight of a car, fuel efficiency can be increased by 6% to 8%, and for every 100 kg weight reduction of a car, fuel consumption of 100 km can be reduced by 0.3-0.6 liters and CO2 emissions can be reduced by 1 kg. The use of lightweight materials is one of the main ways to lighten the car.

Basalt fiber: the stone that can build planes and make clothes at the same time

Basalt fiber: the stone that can build planes and make clothes at the same time

Basalt is a common paving stone in China, but after special means of treatment, it can change its form into a high-performance fiber material with a metallic luster - basalt fiber. The strength of this fiber is 5 to 10 times that of steel, but the weight is about one-third of the same volume of steel, compared with the previous, the application value is greatly enhanced. Therefore, some people imaginatively call its manufacturing technology "stone into gold".

Progress on interfacial debonding of basalt fiber-reinforced polymer composites

Progress on interfacial debonding of basalt fiber-reinforced polymer composites

Basalt fiber is a kind of high performance fiber material prepared from basalt ore by using melt drawing process, which has the advantages of non-toxic, excellent mechanical properties and corrosion resistance, etc. It is used to prepare fiber reinforced polymer composites (FRP) and is quite valuable in the fields of transportation and construction. In FRP, the area formed between the fiber surface and the matrix is called the interface, whose main function is to transfer the external load from the polymer matrix to the fiber through the interface, so that the macroscopic properties of FRP can be significantly enhanced. The structure and nature of the interface are especially important for the stress transfer process, and the interfacial debonding between the fiber and the matrix is the main factor leading to the structural damage of FRPs, so it is important to establish the early warning and monitoring technology for the interfacial debonding of FRP materials to evaluate the life and service behavior of the materials.
