Advantages of Carbon Fiber Reinforced Polymer(CFRP): 1. The one-way tensile strength is high, which is about 7-10 times than steel. 2. It is light in weight and only 1 / 4 weight of the steel, which can be operated manually without large machines and equipment; it is pasted on the surface of the structure, with fast construction speed and short period, which has little impact on the life and production of the reinforced structure, and hardly increases the quality of the original structure. 3. Carbon fiber strengthening system is with high modulus of elasticity, can play an important role in strengthening of concrete/steel. 4. It is stable in humid and corrosive environment, and can resist the corrosion of acid, alkali, salt and water because of the stable chemical properties of fiber reinforced composite and resin bonding. 5. Carbon fiber strengthening system is widely used in bridges and other projects,like building beams, columns and floors,tunnels and chimneys,municipal roads,steel pipes,etc; The onstruction performance is superior, easy to cut, and has a high adaptability to the required shape and size. 6.Carbon fiber strengthening system is an economic and effective method for concrete crack reinforcement and foundation repair, and also suitable for repair and reinforcement of pipeline cracks and corrosion.

Black pepper (Piper nigrum) is a flowering vine in the family Piperaceae, cultivated for its fruit, known as a peppercorn, which is usually dried and used as a spice and seasoning. When fresh and fully mature, it is about 5 mm (0.20 in) in diameter and dark red, and contains a single seed, like all drupes. Peppercorns and the ground pepper derived from them may be described simply as pepper, or more precisely as black pepper (cooked and dried unripe fruit), green pepper (dried unripe fruit), or white pepper (ripe fruit seeds).[2] Piper nigrum from an 1832 print Black pepper is native to present-day Kerala in South India,[3][4] and is extensively cultivated there and elsewhere in tropical regions. Vietnam is the world's largest producer and exporter of pepper, producing 34% of the world's crop, as of 2013. Ground dried and cooked peppercorns have been used since antiquity, both for flavour and as a traditional medicine. Black pepper is the world's most traded spice, and is one of the most common spices added to cuisines around the world. Its spiciness is due to the chemical compound piperine, which is a different kind of spicy from the capsaicin characteristic of chili peppers. It is ubiquitous in the modern world as a seasoning, and is often paired with salt and available on dining tables in shakers or mills.
