Advanced Composite & Elastomeric Solutions for Aerospace Applications

Engineered Materials for Aerospace, Defense, and SATCOM Systems

Wm. F. McGraw & Co. in Riverview, MI, specializes in custom-engineered materials developed for demanding precision aerospace, defense, and SATCOM systems. We leverage advanced fabrication methods and comprehensive materials science expertise to create parts that work in high and low extremes. Whether it’s low-orbit satellite hardware, jet interiors, or radar shielding, our solutions balance performance, durability, and weight while achieving the necessary demands of mission-based applications.

Aerospace Material Applications

This engineered system is used on aerospace platforms to maximize structural integrity, protect critical systems, and minimize weight. There are applications from insulation on the flight deck and the avionics compartment, to engine mounts and control surface construction. All solutions are engineered to meet thermal, mechanical, and electromagnetic requirements to be within the industry specifications.

Reinforcement options include:

Glass fibers: It is selected for its mechanical realistic properties as reinforcements that include excellent tensile strength, impact resistance, and dimensional stability. Glass fibres are also ideal for electronic enclosures, mission-critical structural site that have radar compliance and electronics. Glass fibres also have good dielectric insulation; and are chemically resistant and thermally stable for aerospace systems and applications that exposure them to high/harsh environments and electromagnetic fields.

Aerospace Sealing Solutions

Our thermal insulation for aerospace systems includes elastomeric seals and gaskets designed for the highest demands. We deliver both standard and custom geometries, ready for integration into flight control housings, avionics bays, and fluid control panels.

Common Aerospace Material Formats

We stock and convert multiple material types that serve a variety of functions, from insulation and protection to structural load-bearing, electronics shielding, moisture barriers, and environmental isolation for aerospace and defense applications. Our materials are sourced with long-term performance in mind and tailored to meet the specifications of each aerospace project.

Glass-reinforced epoxy laminates: Widely used for mechanical and electrical insulation, these materials offer high strength and dimensional stability. They’re common in terminal boards, spacers, and flame-retardant panels. Their resistance to heat and electrical arcing makes them dependable in high-voltage systems, while their rigidity ensures mechanical reliability across varied stress profiles.
High-performance thermoplastics (e.g., polyaryletherketones, polyimides): These advanced polymers offer excellent thermal stability and chemical resistance. They’re ideal for high-voltage insulation and lightweight shielding in turbine or engine environments. These plastics can endure prolonged heat exposure without losing strength, and they resist solvents, fuels, and oxidizers—perfect for aerospace interiors and hot sections.
Engineering-grade nylons and polycarbonates: Chosen for toughness and clarity, these resins perform well in cockpit applications, switch panels, and interior parts requiring durability without added mass. They offer good impact resistance and are easy to fabricate, which is critical in applications needing frequent inspection or maintenance access.
Thermoset composites for structural support: These systems combine epoxy or phenolic resins with reinforcement to provide heat resistance and rigidity. Applications include frame stiffeners, chassis supports, and thermal bulkheads. They excel in load-bearing areas, maintaining strength even after prolonged thermal cycling or vibration exposure.

Additional Aerospace Uses

Beyond core structures, we supply components that enhance safety, precision, and system longevity across a wide range of mission-critical aerospace systems. These added elements help ensure every aircraft meets evolving operational, environmental, and technological demands.

Composite spacers and shims: These precisely machined components provide reliable alignment during assembly and help maintain structural tolerances. They are engineered from high-strength composites that resist deformation and offer long-term performance under vibration, load, and temperature fluctuations.
Seals for hatches and access panels: Custom-formulated elastomers resist compression set while offering chemical resistance to fuels, oils, and solvents. Designed for repeated use, these seals maintain pressure boundaries and environmental isolation even in harsh climates and operational altitudes.
Covers and enclosures for avionics: Thermally stable and non-conductive materials ensure reliable housing for electronics. These covers prevent arc flash, block debris ingress, and help regulate internal temperature, protecting sensitive circuitry and wiring from performance threats.
Interior panels and dashboards: Lightweight and engineered to meet stringent flammability, smoke, and toxicity requirements, these panels deliver both safety and design cohesion. Textured and colored to match the aircraft interior aesthetic, they add both structure and style to cockpit and cabin applications.

Quality Assurance & Compliance

We ensure every component meets aerospace-grade performance and documentation standards, supporting your project from the earliest design stage to final delivery with measurable consistency.
