300g Carbon Fiber Fabric

With 18 years of expertise in carbon fiber composites for structural reinforcement, JUN TENG integrates raw material spinning, weaving, third-party testing, import/export supply, and technical support services. We are one of the few domestic manufacturers with a complete, end-to-end industry chain for carbon fiber fabric. Our facility features a standardized Class 100,000 weaving workshop and an independent laboratory for mechanical property testing. Every roll of 300g carbon fiber fabric undergoes batch sampling and is issued a CMA-certified test report; all products fully comply with the GB 50367 standard for the design of concrete structure reinforcement.

Application Case Studies

Our 300g carbon fiber fabric has been utilized in over 2,000 projects nationwide, ranging from civil and public buildings to bridge renovations. Having withstood years of real-world load testing, outdoor exposure, and humid underground environments, our product demonstrates a performance degradation rate far lower than standard non-compliant products on the market. It has earned high praise from general contractors, reinforcement teams, foreign trade buyers, and infrastructure agencies alike.

For years, we have supplied key materials for the renovation and reinforcement of the Guangzhou Pazhou International Convention and Exhibition Center and the structural maintenance of the Tianjin Olympic Sports Center. Follow-up inspections years after project completion revealed no cracking, debonding, or loss of strength in the reinforced areas. These long-term results validate our product's stability, making it a preferred choice for public buildings, renovation projects, and overseas exports.

Product Demonstration and Actual Cases

1: Raw materials and finished products in rolls

Real photos of brand new imported continuous carbon fiber raw material and finished product in full rolls, 300g unidirectional carbon cloth, clearly showcasing the smooth and dense surface, neat stitching without skipped fibers or oil stains. The page distinguishes between two supply specifications: industrial large rolls (100m/roll, for engineering wholesale) and small sub-rolls (10m/roll, for retail samples and small home decoration), catering to both large-scale engineering procurement and sporadic customer sample requests.

2: Construction site of Guangzhou Pazhou International Convention and Exhibition Center

The convention and exhibition center is a large-scale commercial public building with dense pedestrian flow. During the renovation and expansion phase, the floor slabs and large-span roof beams suffered from insufficient bearing capacity. The general contractor selected JUN TENG's 300g Carbon Fiber Fabric for reinforcement and strengthening. This is a real-life photo of the standardized process of construction personnel polishing the base surface, mixing glue, and pasting carbon fabric. The carbon fabric has an extremely light weight, which will not add additional load to the roof. The thin-layer construction does not occupy the original space of the building and does not affect the interior decoration and use of the venue.

3: Completion inspection of Tianjin Olympic Sports Center

The Olympic Sports Center has been in use for many years, and minor structural cracks have appeared on the stand columns and the bottom walls. Considering the safety of event use, this Carbon Fiber Fabric is selected for overall reinforcement and strengthening. The annual inspection record taken by a third-party professional organization six years after completion shows that the reinforced area is free of hollowing, detachment, and cracking. Its performance remains stable under long-term exposure to the elements, fully demonstrating the product's outdoor durability advantages.

Core Advantages of Full-Dimensional Products

1.With flexible procurement channels, we offer simultaneous supply for both domestic sales and exports. Our Carbon Fiber Fabric supports both retail sampling for single items and wholesale for large-scale engineering projects. Additionally, we provide a full set of export inspection documents, customs clearance materials, and English inspection reports, catering to overseas building material trade orders from Southeast Asia, the Middle East, Europe, and America. Foreign trade customers do not need to handle additional qualification documents, as we can facilitate one-stop packaging and shipment of products, auxiliary materials, and customs clearance documents.

2.Exclusive one-on-one free technical guidance from engineers throughout the entire process. After placing an order, a dedicated reinforcement technical engineer will be assigned to provide round-the-clock online services, covering the entire process from base surface treatment, primer application, leveling and repair, impregnating glue ratio, carbon cloth bonding, to curing and solidification, with both text and video tutorials. Customized standardized operation plans are provided for novice construction teams and small decoration teams, effectively solving common construction problems such as hollowing, bubbles, poor bonding, and inadequate strength.

3.Comprehensive reinforcement material services, one-stop supply of all auxiliary materials. Purchasing 300g Carbon Fiber Fabric can be accompanied by a full set of construction consumables for the same system, including impregnating glue, primer, leveling putty, roller, scraper, and sanding tools. The material properties are matched to avoid bonding failure issues caused by the mixed use of auxiliary materials from different brands. The factory maintains sufficient inventory all year round, and regular orders are arranged for packaging and shipping within 48 hours. Priority production scheduling channels can be opened for key emergency projects.

4.Woven from virgin carbon fiber filaments without recycled waste materials, it ensures stable performance for long-term use. Low-priced carbon cloth on the market often contains recycled and recycled carbon filaments, which are prone to aging and delamination during short-term use. JUN TENG's full range of 300g carbon cloth is woven from brand-new continuous carbon fiber filaments, free of recycled waste materials. All batches come with CMA test reports, which can be directly used for engineering supervision and inspection. With a comprehensive quality assurance system, free replacement and replacement are provided in case of product quality issues.

Real customer evaluations of benchmark projects

Case 1: Evaluation of the general contractor for the renovation and expansion of Guangzhou Pazhou International Convention and Exhibition Center

The convention and exhibition center has extremely strict control over structural safety standards. In the early stage, after comparing and testing multiple 300g carbon cloth samples on the market, only JUN TENG products exceeded all mechanical indicators. During the construction phase, the carbon cloth was cut smoothly and impregnated evenly, greatly reducing the difficulty of operation for workers. Since completion eight years ago, multiple large-scale exhibition load tests have been conducted, and all indicators of the reinforced parts have been stable. The second-phase expansion project continues to have long-term repurchase cooperation.

Case 2: Feedback from the person in charge of infrastructure procurement at the Tianjin Olympic Sports Center

Sports venues experience high pedestrian traffic and frequent vibrations, imposing stringent requirements on the toughness and durability of reinforcement materials. Previously, the use of carbon cloth from other brands led to issues of local thread detachment. However, after replacing it with JUN TENG 300g carbon cloth for comprehensive reinforcement, there have been no structural hazards detected during annual inspections for six consecutive years. Online technical guidance promptly addresses on-site construction queries, and the supply cycle is stable, fully aligning with the maintenance and construction schedules of the venues.
