This study was conducted to search the composition, tensile strength, and elastic modulus of Orden. Source: Ref A7. 414 Mpa tensile strength. High Tensile Strength Epoxy Compounds. 2)For stripper bolts and others which are subjected to tensile impact loads, the selection is made based on the fatigue strength. The tensile testing of the welded joint. Any given thread material can only fulfil its purpose as long as it has the desired tensile strength. The unidirectional biodegradable composites were made from bamboo fiber bundles and a starch-based biodegradable resin. Tensile strength was measured with GoTech Universal Testing Machine using the standard of ASTM D882-91. 8 c) Materials shall demonstrate minimum specified seal strength when a seal is formed with another specified material under specified conditions. The fibers are 0.
