Aromatic polyamide fiber, wherein aromatic polyamide molecular chains are oriented along the fiber axis to take advantage of the strength of chemical bonds. Aromatic polyamide fiber reinforced polymer composite, which includes a polymer matrix reinforced with aromatic polyamide fabric, pad or strand. Carbon fibers are produced by heating organic precursor materials (such as rayon, polyacrylonitrile or asphalt) containing large amounts of carbon in an inert environment. Carbon fiber reinforced polymer composite, including polymer matrix reinforced with carbon fiber cloth, pad or strand. The catalyst material that accelerates the chemical reaction and enables it to be carried out under more mild conditions than other requirements will not change permanently due to the reaction. Contact critical applications are reinforcement or repair systems that rely on load transfer from the substrate to the system material through contact or support at the interface. Creep fracture of material under continuous load under stress lower than tensile strength. Crosslinking forms a covalent bond that connects one polymer molecule to another. E-glass - A series of glass fibers used to strengthen polymers, consisting of calcium borosilicate alumina, with a maximum alkali content of 2.0%.
