This synthetic polymer material was invented and developed by SRI International in the 1980s and manufactured by Toyobo. [2] In generic usage, the fiber is referred to as PBO. [3] Zylon has 5.8 GPa of tensile strength, [4] which is 1.6 times that of Kevlar. Additionally, Zylon has a high Young's modulus of 270 GPa, meaning that it is stiffer ...
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
Tensile strength or ultimate tensile strength is a limit state of tensile stress that leads to tensile failure in the manner of ductile failure (yield as the first stage of that failure, some hardening in the second stage and breakage after a possible "neck" formation) or brittle failure (sudden breaking in two or more pieces at a low-stress ...
Graphene is known for its exceptionally high tensile strength, electrical conductivity, transparency, and being the thinnest two-dimensional material in the world. [4] Despite the nearly transparent nature of a single graphene sheet, graphite (formed from stacked layers of graphene) appears black because it absorbs all visible light wavelengths.
PCTFE has high tensile strength and good thermal characteristics. It is nonflammable [14] and the heat resistance is up to 175 °C. [15] It has a low coefficient of thermal expansion. The glass transition temperature (T g) is around 45 °C. [1] PCTFE has one of the highest limiting oxygen index (LOI). [16] It has good chemical resistance.
Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
Dyneema Composite Fabric (DCF), also known as Cuben Fiber (CTF3), is a high-performance non-woven composite material used in high-strength, low-weight applications. It is constructed from a thin sheet of ultra-high-molecular-weight polyethylene (UHMWPE, "Dyneema") laminated between two sheets of polyester. [1] [2]
This material, also known as an aircraft alloy, is heat treatable. [ 1 ] 7068-T6511 has typical ultimate tensile strength of 710 MPa (103 ksi) versus a similar product produced from 7075-T6511 that would have a typical ultimate tensile strength of 640 MPa (93 ksi).
