In aerospace structures,high-end UAV main-bearing parts,and large sandwich radomes,engineers love One-Shot Co-Curing—laying up carbon fiber prepregs directly onto the core and sending them into the autoclave together to maximize efficiency.
But for standard structural foams,this is a brutal trial.Under 180°C and 5–7 bar of autoclave pressure,any micro-weakness in the core leads to catastrophic out-of-plane creep,fiber waviness,or cell collapse.
Designed precisely for these extreme boundaries,our XTylene®Tx Series(High-Performance Aerospace-Grade)PMI Foam is engineered to conquer"high-temperature+high-pressure+co-curing"environments.
Why High-End Aerospace Programs Specify the Tx Series:
1️⃣Direct Co-Curing Without the Tedious"Pre-Crush"
To prevent core collapse,shop floor technicians often have to"pre-crush"cheaper foam grades before layup—a process that adds labor,time,and degrades core properties.With a massive glass transition temperature(Tg:210–235°C),the Tx Series remains safely in its rigid glassy state at 180°C,retaining a high percentage of its room-temperature compressive strength.No pre-crushing needed;just lay up and cure.
2️⃣Standing Strong Against the Resin"Exotherm Peak"
Thick,complex carbon fiber layups generate massive exothermic heat during cure.The actual temperature inside the laminate often spikes far above the autoclave's 180°C setpoint,sometimes nearing 200°C.Standard foams shrink or melt under this thermal surge.The Tx Series offers a safe thermal buffer,maintaining perfect dimensional stability and protecting fiber alignment.
3️⃣High Crosslink Density=Negligible Creep Under Autoclave Pressure
Autoclave pressure exerts high,multi-directional forces on sandwich panels.Any microscopic core deformation alters the fiber volume fraction.Thanks to its highly crosslinked aromatic polymer matrix,the Tx Series exhibits negligible creep deformation under 180°C at 7 bar,securing razor-sharp thickness tolerances for the finished part.
