KR> Fuel tank pressure test
I believe that is the way most RV builders do it. Vans has a kit for that. My Panther Building Documentation at PantherBuilder Web Site Daniel R. Heath -?Lexington, SC -Original Message- To pressure test a tank you use a pressure gauge connected to a T fitting screwed in to the tank. One of the T connections to the tank Another to the pressure gauge The third to the valve Open the valve to allow air to go in to the tank Close the valve and make sure the pressure doesnt drop after a set time say 24 hours. Open valve to vent the tank and then unscrew the T.

KR> Comparison of Carbon Fiber, Kevlar (Aramid) and E Glass used in Composites for Boat building.
Although this is for boats I thought it might be of interest to the list for aircraft * Comparison of Carbon Fiber, Kevlar (Aramid) and E Glass used in Composites for Boatbuilding.* *For more detailed description of the characteristics of Kevlar and Carbon Fiber follow the links at the top.* *Epoxy* Your can't talk about composite fibers without introducing epoxy. Epoxy is used to bind whatever strengthening fiber is being used and to lock them in position so they can stay in position to do their job. Fiber reinforced structures usually have the fibers running in specific directions to focus the reinforcement where it is needed and the epoxy keeps the fibers where they are needed. Although the main purpose of the epoxy matrix is to adhere to and transfer the loads to the fibers it is a strong material in its own right. It helps protect the fibers from damage and provides impact resistance. Polyepoxide or as it is better known Epoxy, is a thermosetting network polymer which forms when an epoxyide resin reacts with a polyamine hardener. The resulting Epoxy polymer is heavily cross linked (networked), and thus strong, hard and rigid. It is also somewhat brittle. Epoxy has found a wide range of applications, including fiber-reinforced plastic materials, general purpose adhesives and strong chemically resistant coatings and finishes. Although epoxy bond mechanically if the surfaces are rough, the strongest bond is by far an ionic bond with its reinforcing fibers. That's why not all fibres are suitable as epoxy composite. The epoxy simply does not stick to everything. Epoxy has proved to be a relatively safe material. The main risk associated with epoxy use is sensitization to the hardener which can result in serious allergic reactions, which can occur even after a few days. This can become asthma in sensitive individuals. Bisphenol A, which is used in epoxy resin, is a known endocrine disruptor. It's always better to protect yourself by working with gloves and at the very least have a well ventilated area. Respirators are helpful if you have a tendency to react to chemicals. Cured Epoxy is very resistant but will degrade if exposed to UV. The surface becomes chalky and looses strength. For this reason it needs to be coated with UV protection. Epoxy strength is degraded when exposed to higher temperatures. Over 350 ?F (177 ?C). ** *Tensile Strength* *Tensile Strength* Tensile Strength is the maximum stress that a material can withstand, while being stretched, before if fails. Some non brittle material distorts before breaking, but Kevlar, Carbon Fiber and E glass are brittle and fail with almost no distortion. It is measured in Force per unit area: Pa or Pascals. Ultimate tensile strength (UTS) or ultimate strength are terms also used. Stress is the force, strain is the deflection due to stress. *Comparing the Tensile Strength of E Glass, Carbon Fiber and Kevlar (Aramid) MPa* Note: These figures are for comparison purpose. They can vary with the manufacturing process, composition of the epoxy, formulation of the aramid, precursor fibre for the Carbon fiber. Fibre Strength Laminate Strength E Glass 3450 1500 Carbon Fiber 4127 1600 Kevlar 2757 1430 Epoxy N/A 12-40 The tensile strength of Carbon Fiber, Kevlar and Glass is similar. This comes as quite a surprise to many people. When making comparisons it's important to note that there are differences in each of the materials in manufacturing processes, precursor materials, and after-treatments. These all influence the strength. The figures are given for comparison only, The figures given in this article mostly come from Wikipedia and from the spec sheets of manufacturing companies. In the end if *Tensile Strength* is your only concern, use e glass. ** ** ** ** *Density and Strength to Weight Ratio* *Weight per Unit Volume or Density of Carbon fibre, Kevlar, and E Glass* The Denser a material is the heavier it will feel for an equal sized chunk. When we compare the density of our 3 materials we see a significant difference. If we make up 3 samples exactly the same size and weight them we quickly see that Kevlar fiber is much lighter, Carbon Fibre is next and the E Glass is the heaviest. So for the same weight of composite we get more strength. In other words, any structure where we require a given strength can be smaller, or thinner if made out of carbon fiber or Kevlar composite than if made out of glass. If you wanted to do this comparison for yourself you could prepare 3 samples of exactly the same size. After weighting them you would then test them for strength. Once you looked at your results you would see that the strength of the 3 samples is about the same. You would also find that the Glass composite is almost twice as heavy as the Kevlar or the Carbon Fiber Laminates. In other words it takes half as much Carbon or Aramid fiber to get the same

KR> Fuel tank pressure test
It's worth reminding folks that we are talking very low pressure here, in the order of one PSI or less, if you don't want to blow up your tank. I've checked my lungs with a high resolution pressure gauge, and I can bearly blow 1 psi, for an instant. The balloon method prevents disasters that can happen when using an air compressor for this job. Personally, I build the bottom of the tank and fill it with gasoline for the night, and come back and check it the next day, then install the top onto a bed of flox, and glass the outside of the joint again. By filling the bottom, you at least prove the critical bottom four joints are good before you button the whole thing up. If it leaks around the top, you can either fix it or don't fill it quite all the way up. N56ML's header tank was that way, but I learned from the experience and never had another leak on the other two tanks. Mark Langford ML at N56ML.com http://www.n56ml.com

Well, that's not true.? It doesn't have all the goodies of the larger version.? It's missing wi-fi so any ADS-B equipment would need to be hooked up via serial to mini-USB.? Which isn't a bad idea.? A mass corona ejection would knock out wi-fi too.? The iFly 720 model is down to $699, limited quantities.? Why can't they just say $700?? Everybody does this . . . do they think they're fooling us??
