The demand today in commercial and military markets alike is for lightweight,
multi-functional structures that are cost-effective, safe and efficient. Response
has been limited because of the complexity of the demand. Cellular Materials
International, Inc. (CMI), however, offers structures that are lightweight and
multi-functional in a variety of designs and materials. Its
advantages are that these materials are
lighter than traditional metal forms (solid sheets), more functional than
traditional cellular materials (honeycombs, metal foams), and therefore can be more cost-effective and
environmentally friendly than any competitor material.
CMI develops and manufactures a set of proprietary structures based on a periodic
cellular material (PCM) technology that is very light, very strong, efficient with
heat exchange, multi-functional, and versatile due to its design and material
flexibility. CMI's PCM is now being incorporated into advanced
applications that require structural support, armor
protection, and thermal management or any combination of these functions. These
structures' multi-functionality could mean anything from enhanced performance of
a fuel cell to increased payloads for spacecraft to personnel protection.
CMI's periodic cellular materials are comprised of a metal
core sandwiched between two face sheets. The core is fabricated and then bonded to
the face sheets through exceptionally strong nodes. CMI utilizes a wide variety of
designs for its proprietary structures collectively referred to as Microtruss™.
Both the core and face sheets are manufactured from proven and established
commercial, wrought alloys employing standard metallurgical
processes in a variety of designs, densities, and metals, depending on the
specifications of the application.
The versatility of CMI's Microtruss™ materials makes them ideal for diverse
applications such as jet blast deflection on aircraft carriers, blast and ballistic
protection on armored vehicles, heat management for electronics storage, impact
defense for vehicle bumpers, and flow separation control in scramjets. The wide
variety of alloys that can be incorporated into Microtruss™ structures enable
the utilization of these structures in harsh environments from marine to aerospace.
