| Description | RTM Resins based on a-ODPA and a-BPDA with kinked diamines exhibit low-melt viscosity (approximately 10 poise). Composites made from a-ODPA resins (T(sub g) = 265-330 C) by RTM display good mechanical properties at 288 C (550 F), but soften at 315 C (600 F). Composites of RTM370 based on a-BPDA retain excellent mechanical properties at 315 C, exceeding BMI-5270-1 capability. |
