Is there any relation between crystallinity and mechanical properties in polymers? Built to Last: Sheet Metal Design with Strength in Mind | … However, if the same strap was made with a ratchet that had an 8,000 pound break strength, then that would reduce the overall product strength to 8,000 pounds; even though the webbing is rated for 10,000 pounds. The design of reinforced concrete columns and beams is very important to provide structural How to rip apart molecules. As we see in many cases the strength and elongation increases with reinforcement. i want to know the relation between crystallinity and mechanical properties of polymers i.e. As you said, the addtion of elastomer may result in a decrease of polymer rigidity, so the rigid fillers can be used as a second reinforcement  to banance the rigidity and toughness pf the materials. Since the hardness increases with the increase in strength and increase in hardness led to increase in brittleness. the results of hardness and tensile strength were showing the same trend(hardness is decreasing and in the same way tensile strength is also decreasing). How can this be explained? In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain.It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing).These curves reveal many of the properties of a material, such as the Young's modulus, the yield strength … In most cases these limits will either be printed, or tagged on each strap, be sure to reference them before use.

For instance, the modification of the terminal carbon atoms with appropriate functionalities can induce extra hydrogen bonding supra-molecular network which in term enhanced the segmental mixing between the hard-soft segments displayed significantly higher mechanical properties. I want to know if there is a class of materials which can help me to achieve this. When it comes to ratchet straps, winch straps, and just about any other type of strap in the cargo industry, the words Working Load Limit (WLL) and Breaking or Break Strength are commonly seen. PE and PP. The tensile strength of my material is increasing with increased filler addition. I want to know how Tensile strength depends on Young's Modulus. can any one please tell me the reason behind it. An example of a tag sewn on a Cargo Equipment strap with the Working Load Limit. Please call for applications with depths less than 6 inches. A failure in the strap could not only be costly, but dangerous as well. The addtion of elastomer in polymer matrix by physical mixing is usually used for increasing the toughness of  the composite materials. In general case, I think there is not a recipe. One popular plateau breaking method is the 10 sets of 10 reps (10x10) bodybuilding training plan. Therefore a strap with a breaking strength of 15,000 pounds, will have a Working Load Limit of 5,000 pounds. I think it depends on the materials you are using. These numbers let the user know how much weight that object is capable of securing. A winch strap with a WLL of 5,000 pounds, should not be used to secure any load above that weight. Note: Using smaller drill bit will reduce expanding strength. How it is possible?
