It is applied in components of aviation, aerospace, sports equipment with resininjection process to reduce the weight. PMI core makes it possible to produce sandwich components in a single step (co-curing), resulting in reduced overall production time. It is highly suitable with autoclave technologies and vacuum infusion processes, including RTM (Resin Transfer Moulding) and VARTM (Vacuum Assisted Resin transfer moulding) processes. Its cell size is small, achieves an optimal compromise between low resin absorption and satisfactory bonding of the facings to the core. MECHANICAL PERFORMANCES Density kg/m³ Compressive creep (%) Standard thickness range Thickness tolerance Note: 1-4mm thick sheet is supplied in 1/4 or 1/2 sheet size. All heat-treated sheets supplied in sealed aluminum packaging Processing and production PMI is especially suitable for vacuum infusion and RTM processes due to its optimized cell structure, where it can be used at temperature up to 180°C with pressure up to 0.7 MPa after heat treatment. Thermoforming and shaping PMI can be easily thermoformed or CNC machined to meet customers’ requirements, bringing tremendous manufacturing advantages. High precision, pre-shaped and ready-to-use foam cores in complex or simple geometries can also be supplied by the Machining Department.
