China Education Equipment Purchasing Network News: The fuselage of the European jet fighter is mainly composed of fiber-reinforced polymer composite materials. This material is lighter in weight, higher in strength and hardness than equivalent metal materials; but it has poor plasticity. Fiber reinforcement is essentially a planar mechanism, and it cannot absorb and release the impacts it receives. As for the aircraft panel, it is very difficult to detect subtle impact damage, but it has an important impact on the mechanical properties of the material. Imitating the self-healing process of biological bones, the researchers introduced a channel system in the fiber-reinforced polymer composite material, and injected resin to repair the damaged parts of the material. The compressive strength of the repaired composite material can reach 97% before the damage. Dr. Richard Trask from the University of Bristol and colleagues tried to solve this problem by making the material self-healing. The bones of our body are also composite materials composed of layered brittle units. However, when a crack occurs in the bone, it can be reconstructed by two types of bone cells: osteoclasts and osteoblasts. Osteoclasts can erode bone, and they create channels or ducts in dead bones. Blood vessels take the osteoblasts to the damaged location through these channels and slowly generate new bones. The researchers used a "lost wax" method to introduce a piping system into the polymer composite. If the material is damaged, a repairing resin can be injected into these pipes to repair the damaged part. The experiment found that the compressive strength of the repaired composite material can reach 97% before the damage. This research on the self-repair of artificial materials is of great significance to the development of related engineering fields. The truly attractive lips are those that look delicate and soft, with a natural rosy color, and these can be achieved only through a high-quality lip glaze and a series of skilled application techniques. Lip glaze is a kind of cosmetics that increases facial beauty and corrects the contour of lips.
Lip glaze is a make-up product that moisturizes the lips and enhances the beauty of the lips. Lipstick in liquid form, its texture and appearance are similar to Lip Gloss, but in terms of function, it has a higher degree of coloration than lip gloss. The color is bright and rich, with a certain degree of gloss, and it has easy application and non-stick cup, etc. With many features, it can improve the dullness of the lips caused by pigmentation after application. The lip glaze will quickly form a film on the upper lip to achieve moisturizing effect.

Most lip glazes are filled, some are long or cylindrical, and the texture is liquid. Lip glaze is particularly good in terms of moisturizing and moisturizing effect. It can feel moisturized every time after applying it to the mouth, so there is no need to worry about the phenomenon of dryness and peeling.
