Products in Powertrain & UTH: Core Material

Polyumac Stru-Cell Structural PVC P100 is a high performance PVC foam core that sets the standard for sandwich composite structures. As well as its excellent strength to weight ratio, it offers good dimensional stability at elevated temperatures and its closed-cell construction means that it does not absorb water.

Toray Nomex® Honeycomb Core—Aerospace Grade is manufactured from Nomex® paper sheets and is coated and bonded together with a phenolic resin. Designed to offer users and designers high strength-to-weight properties at relatively low cost, Nomex® honeycomb is particularly suitable as a core material for production of sandwich structures requiring significant FST performance and using high performance fiber reinforced composites as the facing material.

Toray Nomex® Honeycomb Core—Commercial Grade is manufactured from Nomex® paper sheets and is coated and bonded together with a phenolic resin. Designed to offer industrial users and designers high strength-to-weight properties at relatively low cost, Nomex® honeycomb is particularly suitable as a core material for production of nonmetallic sandwich structures using high performance fiber reinforced composites as the facing material.

Toray Toray MicroPly™ SC72A is a 120°C (248°F) curing low-density unsupported epoxy syntactic core. Toray MicroPly™ SC72A offers reduced processing, a one-shot cure, the ability to anchor inserts or fastenings, and increases the opportunity to consider lightweight, thin-walled composite sandwich structures. Considerable cost reductions can be realized when SC72A replaces prepreg as the core material, and where sandwich cores below 3 mm are difficult to achieve in honeycomb core, Toray MicroPly™ is a superior alternative. Toray MicroPly™ SC72A is available in a variety of thicknesses down to 1 mm and is easily contoured and shaped. SC72A is supplied on a roll (15 m x 400 mm) or in sheets (625 mm x 400 mm). Toray MicroPly™ SC72A is compatible for co-cure with Toray E720 and E722 mid temperature curing prepregs.

Polyumac Stru-Cell Structural PVC P60 is a high performance PVC foam core that sets the standard for sandwich composite structures. As well as its excellent strength to weight ratio, it offers good dimensional stability at elevated temperatures and its closed-cell construction means that it does not absorb water.

Toray Toray MicroPly™ ES72A-2 is a 125°C (257°F) curing low-density, expanding, unsupported, epoxy syntactic core. ES72A-2 offers reduced processing, a one-shot cure, the ability to anchor inserts or fastenings, and increases the opportunity to consider lightweight, thin-walled composite sandwich structures. ES72A-2 can be easily contoured and shaped. Toray MicroPly™ ES72A-2 expands using a closed cell process ensuring complete homogeneous cell structure, the density/strength may be altered simply by changing cure pressure or limiting the volume available for expansion, the material is capable of expanding up to 650%. Toray MicroPly™ ES72A-2, formerly Amspand, is available in a variety of thicknesses down to 1 mm, and is supplied in sheets (625 mm x 400 mm).

Toray’s aluminum aerospace (AAA) grade honeycomb core is available in corrosion-resistant 5052 and 5056 alloys. Designed predominately for use in sandwich structures to produce highly engineered structural components. In particular, the material offers the designer high strength-to-weight properties at relatively low cost, aluminum honeycomb is particularly suitable as a shear carrying core in adhesively bonded sandwich panel assemblies.

Polyumac Stru-Cell Structural PVC P80 is a high performance PVC foam core that sets the standard for sandwich composite structures. As well as its excellent strength to weight ratio, it offers good dimensional stability at elevated temperatures and its closed-cell construction means that it does not absorb water.

Polyumac Stru-Cell Structural PVC P130 is a high performance PVC foam core that sets the standard for sandwich composite structures. As well as its excellent strength to weight ratio, it offers good dimensional stability at elevated temperatures and its closed-cell construction means that it does not absorb water.

Aluminum Flex-Core® honeycomb utilizes either 5052 or 5056 alloy foil material and is available in two cell sizes. FlexCore® has unique cell configurations that significantly reduce anticlastic behavior and permit small radii of curvature without deformation of the cell walls or loss of mechanical properties. Aluminum Flex-Core® has been developed to allow the designer and fabricator freedom in the utilization of honeycomb for components requiring simple and compound curvatures. Highly contoured sandwich panels such as leading edges and flaps, nacelles, fairings, doors, and access covers, and other parabolic, spherical, and cylindrical shapes are prime Flex-Core® candidates. Duplicate die model and control tooling for aerospace use are also examples of Flex-Core® Applicationss. As with standard aluminum honeycomb, Flex-Core® provides controlled crush characteristics without rebound and thus curved energy absorption units become feasible and economical.

Polyumac Air-Comb PP8-80 is a polypropylene honeycomb material that combines lightweight, strength and resilience. It is suitable for a wide variety of sandwich core applications in marine, road/rail transportation, industry and infrastructure. Air-Comb also possesses excellent sound damping properties.

Toray Toray MicroPly™ SC8020A is a low-density unsupported epoxy syntactic core. The material has been developed to offer a long out life and flexible cure schedules at 70°C to 130°C (158°F–266°F). Toray MicroPly™ SC8020A offers reduced processing, a one-shot cure, the ability to anchor inserts or fastenings, and increases the opportunity to consider lightweight, thin walled composite sandwich structures. Considerable cost reductions can be realized when SC8020A replaces prepreg as the core material, and where sandwich cores below 3 mm are difficult to achieve in honeycomb core, Toray MicroPly™ is a superior alternative. Toray MicroPly™ SC8020A is available in a variety of thicknesses down to 1 mm, is easily contoured and shaped. SC8020A is supplied on a roll (15 m x 400 mm) or in sheets (625 mm x 400 mm). Toray MicroPly™ SC8020A is compatible for co-cure with Toray’s E720, E722, and 8020 prepregs.

Polyumac Stru-Cell Structural PVC P200 is a high performance PVC foam core that sets the standard for sandwich composite structures. As well as its excellent strength to weight ratio, it offers good dimensional stability at elevated temperatures and its closed-cell construction means that it does not absorb water.

Toray Advanced Composites’ aluminum commercial (AAC) grade honeycomb core is manufactured from corrosionresistant 3003 alloy foil. Designed to offer industrial users and designers high strength-to-weight properties at relatively low cost, aluminum honeycomb is particularly suitable as a shear carrying core in adhesively bonded sandwich panel assemblies.
