Polylactic acid (PLA) fiber is made from starch raw materials such as corn and wheat, converted into lactic acid by fermentation, and then polymerized to obtain PLA, which is made by solution spinning or melt spinning. It is a fiber that completes the natural cycle and has biodegradability.
The fiber does not use petroleum and other chemical materials at all, and its waste can be decomposed into carbon dioxide and water under the action of microorganisms in the soil and seawater, so it will not pollute the earth's environment. Since the initial raw material of this fiber is starch, its regeneration cycle is short, about one to two years, and the carbon dioxide it produces can be reduced in the atmosphere by plant photosynthesis.
Long carbon fiber reinofrced PLA
Carbon Fiber (CF) is an inorganic fiber containing more than 90% carbon. It is made by cracking carbonization of organic fibers under high temperature environment to form carbon main chain mechanism.
As a new generation of reinforcing fibers, carbon fiber has excellent mechanical and chemical properties, including:
1) Light weight. Carbon fiber density and magnesium and beryllium is basically equivalent to less than 1/4 of steel, the use of carbon fiber composites as a structural component material can make the structure quality reduction of 30% -40%.
2) High strength and high modulus. The specific strength of carbon fiber is 5 times higher than that of steel and 4 times higher than that of aluminum alloy; the specific modulus is 1.3-12.3 times higher than that of other structural materials.
3) Small coefficient of expansion. Most of the carbon fiber at room temperature coefficient of thermal expansion is negative, the coefficient of thermal expansion under high temperature conditions is small, it is not easy due to high working temperature and expansion and deformation.
4) Good chemical corrosion resistance. In the acid, alkali environment are very stable performance, can be made into various types of chemical corrosion products.
5)Strong fatigue resistance. Its composite materials by stress fatigue millions of cycle test, strength retention rate is still 60%, while 40% of steel, aluminum for 30%, glass fiber reinforced plastic is only 20% -25%.
Carbon fiber composites are the re-enforcement of carbon fiber. Although carbon fiber can be used alone and play a specific function, however, it is ultimately a brittle material, only with the combination of matrix materials to form carbon fiber composites, in order to better play the mechanical properties, to carry more load.
Long carbon fiber & Short carbon fiber
Long carbon fiber (LGF): 6-25mm/ High performance, high cost
Short carbon fiber (SCF): less than 6mm/ Low performance, low cost
In the composite material made of fibers is sheared or pulled, the fibers are pulled out from the matrix, such a pulling process is conducive to the absorption of energy provided by the loading, the longer the fibers are within a certain length, the greater the absorption of energy, and the more significant its strength. And in the same volume amount, due to the longer the single fiber, the fewer the number of fiber roots, the less stress concentration generated at the fiber end, the more difficult the destruction of the material. From the results of the feedback of practical applications, the various properties of long carbon fiber reinforced thermoplastic composites are more excellent than those of short fibers.
●Will the use of Xiamen LFT-G materials increase the cost?
a. The unit cost of the material is slightly higher than aluminum alloy, but the cost/time of secondary metal processing can be saved, which is relatively advantageous overall.
b. The unit cost of the material is slightly higher than that of a homogeneous staple fiber reinforced composite material, but LFRT has high dimensional stability, is not easily deformed, and can be assembled after demolding, which saves cooling/pressure retention time for molding and cost/time for fixing fixtures.
