Carbon fiber composites have different application forms, such as short cut, long cut and continuous carbon fiber reinforcement. As the advantages of carbon fiber composites have been paid attention to in many fields, new carbon fiber composites have emerged as The Times require. The following are the latest application cases of long carbon fiber reinforcement forms. The instrument cabin bracket is an important support component used for carrying cables and instruments in the arrow body structure of space vehicle. It should not only bear the large vibration and impact load in the flight process, but also have the characteristics of light weight, high strength and vibration reduction. Using 6-25mm long cut carbon fiber as reinforcement, nylon PA as matrix, through melt impregnation and other processes to form carbon fiber reinforced composite material, and using it as raw material to make the instrument chamber support method.Because the selected long-cut carbon fiber in the parts of the residual length is longer, good dispersion;The products have higher specific strength, stiffness and excellent impact resistance and fatigue resistance.The scaffold made of carbon fiber composite material has good physical appearance, high specific strength and low shrinkage rate, and can reduce the weight by 50% compared with the aluminum alloy part structure, and can be inlaid with aluminum alloy to assemble the connecting pieces.

With the widespread use of vehicle radar systems, it has also become another attractive feature for consumers, bringing potential revenue and competitive advantages to automobile manufacturers.As a safety device, automobile radar is convenient and inexpensive, which also has a strong appeal to consumers.PBT engineering plastics, which recently passed the test of a benchmark customer in an industry, successfully entered the automotive radar industry, thanks to continuous research and innovation. Characteristics of PBT modified materials: 1. Chemical resistance, high resistance to splashing water, oil, salt, etc., can give the sensor shell excellent protection effect; 2. Anti-jamming performance, resist electromagnetic interference from other vehicles, to provide a high level of protection for sensitive electronic products, radar's absorption range is wider, with the increasing electromagnetic interference problems in the field of road traffic, only to absorb noise and reduce interference can make the sensor play the best performance. 3. Lightweight vehicle, as a functional plastic, can replace the metal shell, thus helping to reduce vehicle weight and improve vehicle efficiency. 4. Stable size, low warpage, convenient assembly.Compared with the standard grade PBT, the plate warpage deformation of the material is significantly improved.

Features of double wall bellows High density polyethylene (HDPE) has excellent chemical stability, resistance to aging and resistance to environmental stress cracking.The HDPE double wall bellows produced by the raw materials belong to the flexible pipe.Its performance is as follows: Strong resistance to external pressure: The outer wall is in annular corrugated structure, which greatly enhances the ring stiffness of the pipe and thus enhances the resistance of the pipe to soil load. In this aspect, HDP giant double-wall corrugated pipe has obvious advantages compared with other pipes. Low project cost: Under the condition of equal load, HDPE double wall bellows only need a thinner wall can meet the requirements.Therefore, compared with the solid wall phase tube of the same material specifications, it can save about half of the raw materials, so the cost of HDPE double-wall bellows is also lower.This is another very prominent feature of the pipe. Convenient construction: Due to the light weight of HDPE double wall bellows, handling and connection are very convenient, so the construction is quick and maintenance is simple.The construction period is tight and construction In the case of poor conditions, its advantage is more obvious. Small friction coefficient, large flow: HDPE double wall bellows with HDPE as the material can pass through a larger flow rate than other pipe materials of phase diameter.In other words, the same flow requirements, can be used relatively small caliber HDPE double wall bellows. Low temperature resistance and impact resistance: The embrittlement temperature of HDPE double wall bellows is -70℃.General low temperature conditions (-30℃ above) construction without special protective measures, winter construction is convenient, and HDPE double wall bellows have good impact resistance. Good chemical stability: Because cement pipe material is steel pipe, to ensure bearing plug effect, trench bottom must deal with level off, had better make foundation layer, and ask construction personnel to have absolute sense of responsibility.HDPE double wall bellows for flexible pipe, the bottom of the ditch is not high requirements. HDPE pipe does not fracture to ground subsidence or crustal change The elongation of HDPE pipe is more than 20 times that of steel pipe and six and a half times that of PVC. Its elongation at break is very high and its elongation is very strong.This means that HDPE tubes are able to deform without breaking in the event of earth subsidence or seismic shifts in the crust.This point is far better than steel pipe, also better than the obvious brittle PVC pipe.This performance has been proved at home and abroad (Hanshin earthquake did not cause pipe fracture;HDPE pipe in Zhinan Baoshan earthquake was not damaged are proof) WEB:WWW.LFT-G.COM Contact:+ 86 135 5947 4625
