Product Description

The paddle produced by Future is made of PMI foam as the core material, and the surface is made of 100% carbon fiber skin. According to the customer’s requirements, choose the appropriate foam core material. Our company mainly uses the molding process to cover the carbon fiber prepreg on the foam. On the core material, a carbon fiber paddle with smooth surface, light weight and high strength is obtained.

The production process of two PMI foams is described below:

Molding process: The cost of the mold is relatively high. The advantage is that the thickness and size of the composite material can be accurately guaranteed. At the same time, there are two components with smooth surfaces. The components that usually use the molding process include flight control components, helicopter rotors, sports equipment and medical bed boards. Wait. In the molding process, by giving the foam core a certain amount of interference, the interference provides a back pressure for the curing of the panel during the mold clamping and curing process. The compressive creep resistance of PMI foam is the premise and guarantee for the conversion of the interference into back pressure. By setting the appropriate interference, the back pressure can be adjusted according to the resin content of the laminate, the curing system, and the thickness of the panel. Meet the requirements of curing pressure.

Autoclave process: It is characterized by a hard mold on one side and a soft mold on the other side. The curing composite laminate is pressurized by evacuation and pressurization in the autoclave. If the co-curing process is used, that is, the curing of the carbon fiber composite material panel and the bonding of the sandwich structure core material and the panel are completed at one time. The gap of PMI foam is smaller than that of honeycomb, which can provide sufficient support for the curing of the panel, and will not have the telegraph effect like the honeycomb structure panel.

Future will provide the suitable solution for each project with GB standard testing report for each order.
