Carbon fibre is classified as non conbustible and has no listed flash point. Consult an expert, and be careful. In turn these ribbons align themselves within fibers. See my article on Heat Conductivity of Carbon Based materials including carbon fibre, nanotubes and graphene. They have a number of instructional video. strength and rigidity are different properties, facilitate Galvanic Corrosion in fittings, when carbon fiber fails it usually fails catastrophically, The orientation of the fibers AND the different fiber layer orientation, Tensile strength or ultimate strength, is the maximum stress that a material can withstand while being stretched or pulled before necking, or failing. I'm not an engineer. Carbon fiber can have a broad range of CTE's, -1 to 8+, depending on the direction measured, the fabric weave, the precursor material, Pan based (high strength, higher CTE) or Pitch based (high modulus/stiffness, lower CTE). Here is a link to a YouTube video by Easy Composite Ltd. on various techniques using Carbon Fibre. Materials such as Aluminium, titanium, magnesium, Carbon and glass fiber, high strength steel alloys all have good strength to weight ratios. I don't know of any process where fibers are shaped AFTER carbonizing. The first steps are carbonizing and stretching precursor fibers, either PAN: Polyacrylonitrile, Pitch or Rayon. Special types of Carbon Fiber have been specifically designed for high or low thermal conductivity. I have the following book and have found it useful. Although carbon fibers themselves do not deteriorate measurably, Epoxy is sensitive to sunlight and needs to be protected. Moulds and mandrels are major expenses as well. Note that strength and rigidity are different properties, strength is resistance to breaking, rigidity is resistance to bending or stretching.

Strength of a material is the force per unit area at failure, divided by its density. There are a number of systems of measures depending on metric or imperial units. In order to maximize Carbon Fiber Characteristics, a relatively high level of technical excellence must be achieved. The matrix either epoxy or polyester, can however be toxic and proper care needs to be exercised. email me if you find mistakes, I'll fix them and we'll all benefit: For more information on stiffness and how it is measured, Here is a research paper on Conductive Textiles and their use in Combat Wound Detection. Remember stress is force, strain is deflection such as bending or stretching. Test have shown that failure is unlikely to be a problem when cyclic stresses coincide with the fiber orientation. Proper alignment of the carbon fibres is essential to maximize their benefits. High Strength to weight ratio; Rigidity; Corrosion resistance; Electrical Conductivity; Fatigue Resistance; Good tensile strength but Brittle; Fire Resistance/Not flammable; High Thermal Conductivity in some forms; Low coefficient of thermal expansion; Non poisonous; Biologically inert; X-Ray Permeable; Relatively Expensive Because of the way the crystals of carbon fibre orient in long flat ribbon or narrow sheets of honeycomb crystals, the strength is higher running lengthwise than across the fibre. The orientation of the fibers AND the different fiber layer orientation, have a great deal of influence on how a composite will resist fatigue (as it has on stiffness). I don't claim to be an expert. I try to use "reliable sources" such as manufacturer's data, research papers or university articles. If you take a strip of plastic bag, it will stretch and at one point will start getting narrow. Other matrices (whatever the carbon fiber is embedded in) might also be reactive. Carbon fiber is also offered as chopped strands and powder. The units are W/(m.K). Low Coefficient of Thermal expansion makes carbon fiber suitable for applications where small movements can be critical. Depending on the starting material and process of carbonization Carbon fiber is modified to suit the end purpose. The original size and shape of the fibre will remain in the finished carbon fiber, but the interior chemical structure will have been greatly modified through the various heating cycles. Type of carbon fiber and resin 2. Carbon Fiber's reputation as a material has taken on mystical proportions! Quality – Uniformity of fiber distribution, voids, etc If you read research where strength/stiffness is compared, the researchers will always explain how their samples were manufactured including the type of matrix, alignment of fibres, ratio of fibres to matric among other factors. This information is for general knowledge only. The low maintenance requirement of carbon fiber is a further advantage. Careful installation can reduce this problem.
