Hello,
We are a Research Institute from Bucharest, Romania, and we would like a price quotation/sqm for two kind of prepregs (autoclave processable), both with cyanate ester resin OR cyanate ester+epoxy blend, differing by Carbon Fiber type.
Our application is a research project (space), having as target the manufacturing of a satellite electronic housing structure.
For this, we need :
As Resin: cyanat ester or cyanat ester+epoxy blend with the following features :
- Tg minim 150C
- Low moisture absorption (very small CME)
- High resistance to erosion (H atoms) - excellent resistance to micro-cracking
- Very low outgassing
- Resistance to radiation environment (on low orbit)
- Thermal resistance in service (long exposure) curing + postcuring; up to 130 C
- High dimensional stability after curing/postcuring in the range of (-60 up to 130 C)
- max 120 sqm
As fiber: Carbon, unitape:
Prepreg 1 - Ultra High Modulus (>450 GPa)
- 60 % fiber vol. fraction, ply thickness 0.15- 0.18mm
- Max tensile strength in static traction regime, minim 1500 Mpa
- Elasticity modulus, minim 300 Gpa
- Compressive strength, minim 500 Mpa
Prepreg 2 - High thermal conductivity (minim 500 W m-1 K-1)
- 60 % fiber vol. fraction, ply thickness 0.15- 0.18mm
- max 120 sqm
I would very much appreciate if you will send me your offer as soon as possible.
If you have any additional questions related to our application, please do not hesitate to contact me,
Kind regards
