SHD Composites supplies advanced prepreg materials for defense applications. We work with manufacturers, engineering teams and programme partners across structural components, high-temperature applications, tooling and specialist composite systems.
Our range includes carbon fibre, glass fibre and unidirectional prepregs with epoxy, BMI, cyanate ester and fire-retardant resin systems. Options are available for autoclave, oven, out-of-autoclave and press processing.
We support customers from early material selection through development, testing and production supply. With domestic manufacturing in the US, UK and Europe plus industry-leading technical expertise, we help teams make informed material choices and move from development into production with greater confidence.

We supply prepreg systems for defense structures where strength, stiffness and toughness matter. Our technical team can help match the resin system, reinforcement and cure route to your component, production process and service conditions.
Some defense components need to perform under sustained heat or rapid changes in temperature. We offer high-service-temperature epoxy, BMI and cyanate ester prepregs for demanding component and tooling applications.
Where fire, smoke or heat performance is a key requirement, we can help you identify suitable fire-retardant prepreg systems. Material selection can take into account the manufacturing process, reinforcement and relevant fire-performance criteria.
The right tooling can improve speed, repeatability and process control. Our 10 tooling systems cover low-temperature cure, long outlife and high-temperature requirements for prototype, development and production tooling.
Our technical capabilities include specimen manufacture, mechanical testing, thermal analysis, rheology, accelerated weathering and infrared. We can support development trials and qualification programmes, so your engineering team has clearer data before moving into wider production.
Material needs often change as a defense programme develops. We can support smaller development quantities as well as larger production requirements with technical input and manufacturing capability across multiple regions.
Choosing the right prepreg for a defense application involves several factors. Service temperature, structural loads, environmental exposure, cure route and available processing equipment can all influence which material system is suitable.
Production needs matter too. Storage, outlife, tooling, qualification requirements and expected volumes can become more important as a programme moves from prototype into repeat production.
Our technical team can help you assess these requirements early and identify suitable carbon fibre, glass fibre and specialist prepreg options for defense and military composite applications. This gives you a clearer basis for testing and qualification before committing more time and budget.
Tell us what you are developing and the conditions your material needs to handle. Our team can help you identify suitable prepreg systems and the next practical step for your programme.
