Analysis of Differences Between 200g and 300g Carbon Fiber Fabric

Carbon fiber fabric, renowned for its exceptional tensile strength, modulus of elasticity, fatigue resistance (superior to steel), lightweight nature (significantly lighter than steel), excellent chemical corrosion resistance, durability, and ability to conform to complex curved surfaces, has become an ideal material for reinforcing various structures including concrete, steel, masonry, and timber. It is primarily used to enhance the load-bearing capacity of tension and flexural members. Through wrapping confinement, it can also effectively improve the ductility of compression members (particularly valuable for seismic retrofitting), while offering advantages like convenient construction and minimal impact on the original structure.

The common market specifications of 200g and 300g refer to the weight per unit area (grams per square meter). So, what are the specific differences between these two specifications? Dr.reinforcement provides a detailed analysis:

I. Material Usage per Unit Area Differs

200g Carbon Fabric: Weight per square meter is 200g. Using Dr.reinforcement products as an example, it is woven from 25 strands of 12k carbon fiber filaments.

300g Carbon Fabric: Weight per square meter is 300g. Using Dr.reinforcement products as an example, it is woven from 37 strands of 12k carbon fiber filaments.

II. Design Thickness Differs

200g Carbon Fabric: Design thickness is approximately 0.111mm.

300g Carbon Fabric: Design thickness is approximately 0.167mm.

III. Mechanical Properties Differ
The difference in weight directly reflects the number of carbon fiber tows per unit area, leading to significant distinctions in mechanical performance:

Tensile Strength: The design standard tensile strength of 300g carbon fabric typically reaches 3400 MPa, higher than the approximately 3000 MPa of 200g carbon fabric.

Overall Performance: 300g carbon fabric generally outperforms 200g fabric in key mechanical indicators such as modulus of elasticity, elongation at break, and flexural strength.

IV. Recommended Application Scenarios

300g Carbon Fabric: More suitable for large-scale buildings, bridges, and other projects demanding extremely high structural strength reinforcement.

200g Carbon Fabric: Often sufficient for reinforcement needs with moderate strength requirements, such as in small residential houses.

Summary:
The core consideration when choosing between 200g and 300g carbon fiber fabric lies in their physical performance characteristics. In actual reinforcement projects, the selection of the most appropriate specification should be strictly based on structural design requirements and specific engineering needs.

Advantages of Dr.reinforcement Carbon Fiber Fabric:
Utilizes imported, construction-grade 12K high-precision carbon filaments, woven precisely via German-made Dornier intelligent looms. Our unique process ensures highly uniform fiber distribution and robust, stable performance, enabling every filament to participate effectively in load-bearing. This grants the fabric powerful tensile strength. Additionally, the smooth and flat surface facilitates convenient and efficient application during construction.
