High-Temperature PMI Foam Core for Prepreg Autoclave Curing Process

Ultra-lightweight structural core with density from 32 kg/m3, reducing structural weight by up to 30x compared with traditional solid laminates.

Withstands continuous service temperatures of 180 to 210 degrees Celsius, fully compatible with autoclave curing and prepreg molding without thermal collapse.

Ultra-low dielectric constant of 1.03 and dissipation factor as low as 0.0002, an ideal RF-transparent core for radomes and antennas.

100% closed-cell rigid structure with extremely low water absorption, ensuring long-term stability in humid, marine and outdoor environments.

High strength-to-weight ratio: compressive strength up to 3.31 MPa and shear strength 2.56 MPa at 110 kg/m3 (F110 grade).

Outstanding fatigue resistance under cyclic loading, proven in dynamic components such as UAV wings, helicopter blades and racing equipment. 7.

Compatible with all mainstream processes: vacuum infusion, RTM, VARTM, hand lay-up, prepreg lamination and high-pressure autoclave curing.

Full CNC machining and kitting service: grooving, perforation, 3D contour cutting and kit-cut parts supplied per customer drawings.

Large-format supply: blocks up to 2500 x 1250 mm and flat sheets from 1 to 120 mm thick, with custom sizes and tolerances available.

Quality assured with ISO 9001 system, SGS / RoHS / REACH certificates on request; standard sheets in stock, 3-7 days delivery.
