In recent years, due to the growing concern for the environment, scientists and researchers began to use natural fiber instead of synthetic fiber as the main component of composite materials. Rose fiber is a suitable natural fiber. We explained the history, physical description, cultivation methods, and uses of this plant to further understand its potential.

According to the literature review, in the manufacturing of natural fiber reinforced polymer composites, the fiber extraction method, morphology, performance and possible surface treatment of rose fiber to enhance its performance have been extensively studied. However, there is no detailed review on the properties and applications of rose fiber fibers.Therefore, we reviewed Rosestone to determine its potential to better select materials to produce composite materials for use in the construction, construction, automotive and aerospace industries.

Roses belong to the Hibiscus family and are widely distributed in tropical regions.These plants are commonly used for infusion and for producing phloem fibers, and there are two main types. The main economic type is sand grass. India is a straight, sparse annual plant with a height of 4.8 meters. Its jute like fibers are cultivated in India, the East Indies, Nigeria, and to some extent in tropical America.

The stem is green or red, and the leaves are green, sometimes with red veins. Its flowers are yellow, and its calyx is red or green. It is fleshy, spiny, and cannot be eaten. Sometimes, this type of rose is considered to be confused with the genus, which is a slightly similar but more widely used source of fiber.

Another type of rose is yellow grass. Database database. This plant has a short, dense form and is divided into four varieties: white, middle, white, and rubber, all of which grow from seeds.

The calyx has green, red stripes and inedible calyx, while the middle calyx and white edible calyx with chartreuse also produce fiber.Rose species with rose fibers are usually found in a group of shrubs, growing to an average horizontal and vertical height of 2.4 meters per year, with red stems. The stem is usually smooth and cylindrical in shape.

Fibers have been used in ropes, heavy cables, navies, and merchant ships because of their sustainability and long-term non decay in the ocean or freshwater. Fishing nets made of rose colored fibers also have extremely strong resistance and only break under immense pressure. It has been proved that Rosebud contains calcium, niacin, riboflavin, protein, carbohydrates, flavonoids, acids, minerals and vitamins.

Therefore, Roselle is very useful in medical applications. According to reports, this plant has antihypertensive, liver protective, anti hyperlipidemic, anticancer, and antioxidant properties.

In addition, rose sepals are also used as natural food colorants. Finally, produce juice using fresh roses or dried flower pots. In recent years, rose colored fibers have been widely used as reinforcement materials for composite materials and textile engineering.

Rose fiber is a kind of natural fiber, which attracts researchers to explore its ability as a composite reinforcement. Part of the summary paper discusses the chemical and mechanical properties of rose fiber. The difference between plant fibers lies in their composition, that is, the proportion between cellulose and lignin hemicellulose, the orientation or spiral angle of cellulose microfibers.

The structure of phloem fibers is almost similar to that of all fiber types. The basic fiber contains cellulose, lignin and hemicellulose. Usually, the tensile strength and Young's modulus of fibers increase with the increase of cellulose content.

The ductility of plant fibers depends on the direction of the microfibers towards the fiber axis.If the orientation is helical, the fibers are ductile; However, if the orientation is parallel, the fibers are rigid, inflexible, and have high tensile strength. A scanning electron microscope micrograph of the rose colored fiber surface was proposed.

The surface of rose colored fibers is very smooth, but without surface treatment, burrs or foreign particles and dirt may appear. Having a smooth surface is a major disadvantage of natural fiber,This increases its poor hydrophilicity.

However, smooth surfaces can become rough through pre-treatment processes. When the surface is rough, interlocking occurs between polymer materials, thereby improving interfacial bonding.

This phenomenon demonstrates the importance of studying the morphology of fibers, and the morphological results indicate that the morphology of rose fibers is similar to that of Kenyan fibers and other gypsum fibers.

Natural fiber has many advantages and can gradually be used as a substitute for synthetic fiber in the world of materials engineering. Many studies have been carried out on the potential of natural fiber. However, natural fiber also has disadvantages. The key problem related to natural fiber is its hydrophilic behavior, which leads to fiber swelling and may accelerate its biodegradation through fungal attack.

Natural fiber comes from lignfibroin, which contains highly polarized hydroxyl groups.These fibers exhibit the opposite characteristics to thermoplastics, that is, hydrophobic, which is undesirable and limits the potential of natural fiber

These surface treatments have changed the surface morphology and structural elements of natural fiber, and the mechanical properties and thermal stability of these surface treatments have been significantly improved.

Aluminization and mercerization are common surface treatment methods for natural fiber. Numerous studies have been conducted on the effects of diagonalization, indicating positive results in the mechanical properties of composite materials

Alkali treatment can affect the chemical composition of fibers, thereby reducing their water absorption. This result may be due to the removal of lignin and hemicellulose components, wax and fiber oil.

Alkali treatment also reduces the diameter of the fibers, thereby increasing the aspect ratio

Physically, the presence of rough surfaces provides mechanical locking between the fiber surface and the matrix, which may enhance the interfacial bonding between them.

In their review papers, the researchers briefly discussed the manufacturing technology of natural fiber composites, and listed several manufacturing processes adopted from the summer scale.However, the listed manufacturing technologies highlight synthetic fiber reinforced composite materials

As the molding temperature increases, the impregnation quality and fiber dispersion both improve,

summary

Rose fiber is a type of bast fiber with high cellulose content and high tensile properties
