Our Guide to Sourcing Advanced Composite Materials in the U.S.

Sourcing advanced composite materials is a critical decision for engineers in both aerospace and industrial manufacturing. These highly advanced materials often find their way into mission-critical and high-stress applications. Everything from high-temperature industrial machinery to aircraft parts and interiors is on the table.

The reality for engineers and purchasing managers is simple: a single batch of out-of-spec material will force production to stop. It will lead to cost overruns. It could even compromise product safety. Nothing good comes from composite materials that are not up to spec.

If your company is just getting off the ground, your choice of a U.S. composite material supplier is critical. And if you are looking to replace an underperforming supplier that isn’t delivering on quality or lead times, you already know how critical it is to make a better choice this time around.

The True Cost of a Bad Fit

It is not abnormal for manufacturing companies to begin the search for a composite materials supplier by focusing exclusively on bottom-line cost. The lower the price per pound, the more attractive a supplier’s price looks. However, skilled procurement managers know that purchase price is just one small part of a much larger equation.

Is your current supplier a bad fit? If you’re questioning your relationship with that provider, you may be experiencing some common pain points:

• Inconsistent Quality – Material consistency is everything in advanced composites. If resin content varies from one prepreg batch to the next, your manufacturing yield drops. Likewise with poor honeycomb core uniformity and other quality inconsistency issues.
• Creeping Lead Times – A supplier incapable of meeting deadlines makes things more difficult on your end. You’re likely to experience creeping lead times when supplies don’t arrive on time.
• Specialized Applications – Larger, legacy suppliers tend to treat composites like commodities. But if your application requires specific modifications, a legacy supplier might refuse to accommodate them.
• Poor Tech Support – Your team needs technical help when a composite material doesn’t behave as expected. You need access to engineers, and you need it right away. Your legacy supplier might not be giving you that access.

A trusted composite materials partner is one capable of eliminating as many friction points as possible by giving you what you want, when you want it, and with more than enough tech support behind it. It’s what we pride ourselves on here at Axiom Materials.

What Defines a Trusted Composite Materials Supplier

Assuming your company is evaluating potential composite suppliers in the United States, look past the marketing promises. Forget the hype. Instead, evaluate each supplier’s operations based on the following:

1. Quality Management

The best composite materials suppliers in the U.S. don’t just promise quality. They deliver it through rigorous, independent quality management systems. Proper certifications and accreditation underpin those systems.

ISO 9001 certification is the baseline for any professional manufacturing operation. In addition, look for suppliers with AS9100 certification. Note that this certification is a standard requirement in aerospace. In high-performance manufacturing, NADCAP accreditation is also a must.

2. Material Traceability

Certain industries, like defense and aerospace, require that manufacturers be able to trace every component all the way back to its manufacturer and raw ingredients. Your composite materials supplier must maintain meticulous records of everything from raw fiber lots to resin components and manufacturing dates. In the event of a field failure, your supplier should be able to instantly pull the records pertaining to the batch from which those products were made.

3. Comprehensive In-House Testing

A trusted composite material supplier leaves nothing to chance. Generic material data sheets and guesswork are never on the table. Instead, the supplier possesses robust in-house lab capabilities that can test everything from mechanical properties to chemical resistance and thermal performance.

Comprehensive in-house testing ensures that every roll of prepreg is consistent. It ensures that every sheet of honeycomb core performs as expected. Testing validates every gallon of adhesive against your specific technical requirements.

4. Customization and Agility

No two applications are identical, especially in high-performance manufacturing. So as you search for a new composite materials supplier, narrow your search to only those suppliers demonstrating a degree of agility. Your eventual supplier should be able to customize formulations. They should be able to tailor resin systems, adjust fiber architecture, and even customize core dimensions.

In essence, you need more than just a material supplier. You need a strategic partner that understands the intrinsic relationship between your company’s success and theirs. A supplier interested only in selling materials isn’t one you can trust day in and day out.

Why Source Composites Domestically?

No guide of this nature would be complete without discussing domestic composites sourcing. You might be tempted to source your composites from overseas thanks to lower upfront costs. Just know this: domestic manufacturing offers structural advantages that directly affect how you do business.

In high-stakes manufacturing, domestic sourcing impacts your control. It reduces shipping delays, customs bottlenecks, communication barriers, and more. With domestic suppliers, you get:

• Proper regulatory alignment.
• Real-time collaboration capabilities.
• Shorter, more reliable supply chains.

You might pay more for composite materials sourced here in the U.S. But in the long run, you’re likely to save money through a variety of means, including better quality, more reliable logistics, and improved collaboration.

Four Steps to Transitioning to a New Supplier

Whether you’re looking to replace a composite material supplier or searching for your very first strategic partner, we recommend the following four steps:

1. Define your technical baseline.
2. Request material characterization data.
3. Run a first article inspection (FAI).
4. Plan to scale production dynamically.

There is obviously a lot more detail in these four steps, so be sure to ask how we manage them when you contact Axiom Materials. Choosing an advanced composite material supplier boils down to choosing a partner you can trust. We believe we can be that partner for you.

If your current partner is holding you back, contact us. If you’re searching for your very first supplier, we would be honored to earn your business.

FAQs

What certifications should we be looking for in a new composite materials supplier?

At a bare minimum, your supplier should be ISO 9001 certified. Look for AS9100 Rev D certification if you’re in aerospace, and NADCAP accreditation if your manufacturing needs include chemical processes and high-performance testing.

Is raw material traceability really necessary?

Absolutely. Every shipment you receive should come with a Certificate of Conformance (CoC), indicating the ability to trace products back to their raw materials. This information becomes critical when failures occur.

What are standard lead times in the composites industry?

Each composite supplier operates on its own lead time – there is no industry standard. What matters most is that a supplier’s lead time meets your needs and that supplier sticks to it.

What level of tech support should we expect from a new partner?

At a minimum, your team should have direct and immediate access to the supplier’s applications engineering team. Engineers are an invaluable resource when new materials don’t behave as expected.
