PMI foam: PMI (Polymethacrylimide) foam can withstand high temperature composite curing process requirements after proper high temperature treatment, which makes PMI foam widely used in aviation. The medium density PMI f...
Rigid polyurethane foam, referred to as polyurethane rigid foam, is second only to polyurethane soft foam in polyurethane products. Polyurethane rigid foam is mostly closed-cell structure, with excellent thermal insulati...
Brief introduction to the application of PMI foam sandwich foam core material: NASA and European Airbus have recently proposed a foam-filled reinforced strip structure based on the use of sandwich structures and reinforc...
Can be divided into rigid foam, flexible foam semi-rigid (or semi-soft) foam. The core foam is also called porous plastic, which is made of resin as the main raw material and has numerous microporous plastics inside. Wi...
PMI foam is mostly used as a composite sandwich material and has been successfully introduced into many applications. There are currently 154 composite sandwich applications in the fields of radome, stealth, trai...
The simple sandwich structure consists of three parts: the panel, the core material and the glue joint, which transfers the load between the first two components by gluing. The effect of the sandwich structure is to allo...
