Modulus and tensile strength of reinforced fibers for composite materials
2024-07-16
At present, as a common reinforcement fiber for composite materials, there are usually three types: carbon fiber, glass fiber and Kevlar (aramid) fiber. When used for composite reinforcement, the fibers can define the performance standards of the material and are responsible for playing a load-bearing role in the design structure, while the resin matrix is primarily responsible for transferring th...

Compare 11 properties of carbon fiber, aramid fiber and glass fiber
2024-07-16
1. Tensile strength Tensile strength refers to the maximum stress that a material can withstand before stretching. Some non-brittle materials deform before they break, but Kevlar® fibers, carbon fibers, and glass fibers are brittle and break almost without deforming. Tensile strength is measured in force per unit area (Pa or Pascals). Stress is force, and strain is deflection due to stress. Th...

(Ⅲ) How to deal with flow marks on injection-molded parts?
2024-09-27
Mold temperature too low Cause: The low mold temperature causes the molten plastic to cool too quickly in the runner, preventing full fusion. Solution: Increase the mold temperature to ensure the molten plastic flows smoothly and fuses completely. Injection speed too slow Cause: Slow injection speed causes the plastic to flow slowly, extending cooling time and forming weld lines. Solution: Increas...
