1.Low resin absorption rate and high peel strength. Due to the 100% closed-cell structure of PMI foam, the cell pore size is small (pore size is 0.2-0.3mm), and isotropic, PMI foam in the case of low resin absorption rate On the contrary, the peel strength was improved.
| Foam type | Density kg/m³ | Resin absorptivity |
| Fucell PMI(RP) | 60 | 91g/㎡ |
| 80 | 73 g/㎡ |
Remarks: Future made PMI foam RP model series saves about 150kg resin in the actual use of 40M blades.
2.Good compression creep resistance, PMI foam can be applied to various molding processes such as medium temperature epoxy, high temperature epoxy and BMI resin prepreg, with a wide range of process options. And save processing time and cost, and because PMI foam Due to its superior performance, the overall quality of the sandwich structure can be greatly improved under the medium and high temperature molding process.
| Curing process: 130℃, 0.3MPa, 2 hours | |
| Foam type | Creep deformation(%) |
| Fucell PMI (D60 RP) | 1.8 |
| Fucell PMI (D80 RP) | 0.5 |
3. Excellent machining performance, no need for special processing equipment, neat section, smooth surface, good fire performance, no freon and halogen in the foam structure, no release of harmful substances.
4.Has a very low thermal expansion coefficient, good dielectric properties and X-ray penetration properties, high-quality sound insulation, thermal insulation properties.
Future PMI’s unique technical principles and structural characteristics endow the products with good mechanical properties, compression creep resistance, thermal deformation properties and chemical stability, and rely on the advantages of localization, get rid of the shackles of cost, so it has become a different The most widely used core materials in the field sandwich structure can significantly enable customers to optimize the manufacturing process, reduce production costs, and improve production efficiency and product quality.
The current application fields of RP model products are:
◇ Wind turbine blades
◇ Sports equipment
◇ Marine parts
