Prepreg process for carbon fiber yarn
The pre-impregnated carbon fiber material is a composite material produced by carbon
fiber yarn and resin matrix through the coating, baking, cooling, winding, and other
processes, also known as prepreg carbon fiber.
YFCM uses Toray high-end carbon fiber yarn and impregnates it with dedicated epoxy resin
for carbon fiber drive shafts with prepreg machines. The epoxy resin content is
controlled by appropriately adjusting the baking temperature at about RC30%. This
prepreg method can stably control the epoxy resin content to ensure that the product is
light in weight, strong in rigidity, and good in durability.
With high strength and low density, prepreg carbon fiber can be 6-12 times stronger than
steel with only 25% of its density. Prepreg carbon fiber also has remarkable plasticity
that it can be arbitrarily shaped with molds. It's easy to shape and process, corrosion
resistant and has extended longevity.
Dry carbon fiber winding process
- YFCM uses autoclaves to produce carbon fiber tubes.
- Put winded carbon fiber tubes into the autoclave. Apply pressure and heat to solidify the material, and use the internal air pressure to pressurize the stacks.
- Since air pressure exists in all directions, it can pressurize parts with uneven surfaces.
- The pre-set variation curve can be used to control the pressure and temperature.
- The purpose of pressurization during the curing process is to densify the material and remove the gaps between layers.
- It also extrudes excess resin from the fiber while with air bubbles.
- By this point, the pressure of the autoclave can extrude excess resin so that the layers are completely joined for more consistent product quality.
