Standardizing the High Frontier: Rock West Composites and DPP Pultrusion Launch Space-Grade STRATOPultrusion™ Line for Next-Gen Deployables

SALT LAKE CITY, Utah — As the commercial space sector accelerates its transition toward rapid deployment and mega-constellation manufacturing, the demand for standardized, high-performance structural materials has reached an all-time high. Addressing this critical bottleneck, Rock West Composites (RWC), an employee-owned leader in advanced composite manufacturing, has officially unveiled its new space-grade STRATOPultrusion™ product line.

Developed in strategic partnership with DPP Pultrusion, this new offering of pultruded carbon and glass fiber profiles is designed specifically to support next-generation deployable space structures, such as solar arrays, boom antennas, and instrument supports. The product line is making its public debut at the 2026 Small Satellite Conference in Salt Lake City, Utah, where industry leaders have gathered to discuss the future of small satellite technology and agile aerospace procurement.


Main Facts: The STRATOPultrusion™ Announcement

The core of Rock West Composites’ announcement is the introduction of highly standardized, off-the-shelf pultruded rods and tubes engineered to withstand the harsh environments of outer space. Historically, aerospace engineers designing satellites, optical payloads, or deployable systems had to rely on custom-designed, hand-laid composite components. This bespoke approach often resulted in lead times stretching over several months, if not years, creating significant bottlenecks for fast-moving satellite programs.

By partnering with DPP Pultrusion, a Netherlands-based specialist with over 15 years of flight heritage in space programs, Rock West Composites aims to disrupt this paradigm. The STRATOPultrusion™ line introduces several key operational and commercial advantages:

  • Drastically Reduced Lead Times: The new pultruded rods and tubes boast lead times of just four to eight weeks—a fraction of the industry standard for space-qualified hardware.
  • E-Commerce Accessibility: In a move that aligns with the "NewSpace" shift toward simplified procurement, these space-grade components can be ordered directly through RWC’s online store.
  • Broad Orbital Applications: The STRATO™ family is optimized for use across multiple regimes, including Low Earth Orbit (LEO), Geosynchronous Equatorial Orbit (GEO), and Deep Space exploration.
  • Comprehensive Quality Documentation: Each order is shipped with a robust certification package, including dimensional inspections, material certificates, traceability reports, and a certificate of conformance.

At the 2026 Small Satellite Conference, RWC is showcasing physical samples of the STRATOPultrusion™ line at Booth #2219, allowing satellite developers, defense contractors, and researchers to examine the surface quality, stiffness, and structural integrity of the profiles firsthand.


Chronology: The Evolution of the STRATO™ Product Line

The launch of the STRATOPultrusion™ line represents the latest milestone in a calculated, multi-year effort by Rock West Composites to lower the barrier to entry for space-qualified structural components.

[Phase 1: Foundation] ----------------> [Phase 2: Partnership] -------------> [Phase 3: Launch & Beyond]
• Launch of STRATO™ Plates              • RWC partners with DPP Pultrusion    • STRATOPultrusion™ Debut (Aug 2026)
• LEO/GEO Solar Array Substrates        • Joint development of rods & tubes   • Expanded R&D pipeline for new profiles

Phase 1: Establishing the STRATO™ Brand

Recognizing that satellite manufacturers were spending excessive engineering hours designing basic structural plates and sandwich panels, RWC developed the original STRATO™ product line. This family of products offered pre-engineered, low-outgassing, and thermally stable plates and solar array substrates designed for rapid integration. By providing pre-qualified materials, RWC allowed satellite designers to focus on payload development rather than structural material qualification.

Phase 2: The DPP Pultrusion Partnership

While flat plates and sandwich panels solved half the structural puzzle, next-generation deployable space structures—such as roll-out solar arrays (ROSA) and deployable boom antennas—required continuous linear profiles like rods and tubes. Realizing that traditional filament winding and roll-wrapping techniques were too labor-intensive to scale quickly, RWC sought out a partner capable of continuous manufacturing.

They partnered with DPP Pultrusion, a firm globally recognized for its state-of-the-art pultrusion technology. Over the past 15 years, DPP’s materials had quietly built up an impressive track record of reliability in various international space missions. Combining DPP’s manufacturing expertise with RWC’s engineering, distribution, and qualification capabilities paved the way for the STRATOPultrusion™ line.

Phase 3: The August 2026 Launch and Future Pipeline

The culmination of this partnership is the official commercial launch at the 2026 Small Satellite Conference. However, RWC and DPP have indicated that this is only the beginning. While the current catalog features standardized rods and tubes, a robust developmental pipeline is already in place to introduce more complex, high-strain pultruded profiles to meet the evolving demands of deployable space structures.


Supporting Data: Technical Specifications and Material Science

To survive in orbit, materials must endure extreme thermal cycling, vacuum exposure, radiation, and mechanical stress during launch. Standard industrial composites will quickly degrade or fail under these conditions. The STRATOPultrusion™ line is engineered from the molecular level up to meet stringent space agency requirements.

Key Material Properties

Property Space-Grade Requirement STRATOPultrusion™ Performance
Outgassing Low volatile condensable material to prevent sensor contamination. Compliant with NASA SP-R-0022A (Low outgassing).
Coefficient of Thermal Expansion (CTE) Near-zero to prevent dimensional warping during thermal swings. Extremely low to zero CTE.
Stiffness-to-Weight Ratio High modulus to minimize mass while maximizing structural rigidity. High modulus carbon fiber construction.
Creep Behavior Minimal deformation under sustained stowed loads. Ultra-low creep behavior over multi-year storage cycles.
Operational Temperature Stability across extreme hot and cold cycles. Wide, space-qualified operational temperature range.

The Pultrusion Advantage

Pultrusion is a continuous manufacturing process where reinforcing fibers (such as carbon or glass) are pulled through a liquid resin bath and then through a heated shaping die, where the resin undergoes polymerization.

Unlike batch-manufacturing methods, pultrusion offers unmatched consistency along the length of the profile. This process ensures:

  1. High Fiber Volume Fraction: Maximizes the structural efficiency and stiffness of the rods and tubes.
  2. Perfect Axial Alignment: Because the fibers are pulled continuously under tension, they align perfectly along the longitudinal axis, yielding superior tensile strength and a near-zero CTE.
  3. Cost-Efficiency and Scalability: Continuous production minimizes labor costs and material waste, savings that are passed directly to the customer.

Advanced Quality Control and Traceability

Because space missions leave no room for error, every batch of STRATOPultrusion™ products undergoes a strict quality assurance protocol. The base certification package includes dimensional inspection, material certificates, traceability documentation, and a certificate of conformance.

For high-reliability defense and scientific missions, RWC offers optional, advanced testing services, including:

  • Full Traveler Verification: Complete documentation of every step in the manufacturing process.
  • Resin Content Testing: Verification of precise fiber-to-resin ratios.
  • Short Beam Shear Testing: Assessment of interlaminar shear strength.
  • ASTM Test Specimen Coupons: Providing physical material coupons from the same production run for customer-led destructive testing.

Official Responses: Executive Perspectives

Leadership from both Rock West Composites and DPP Pultrusion emphasize that this product line is a direct response to a rapidly changing space industry.

Jeremy Senne, Vice President of the Space Structures Business Segment at Rock West Composites, highlighted the market’s urgent need for rapid procurement:

“We are pleased to have samples of STRATOPultrusion ready for Small Sat this year and look forward to showing it off to our customers. There is market demand for this new product that can compress schedules and lower program risk for challenging applications.”

Senne’s comments underscore a major shift in aerospace management. In the modern space race, schedule risk is often as critical as technical risk. A delay in acquiring structural components can cause a satellite operator to miss their launch window, resulting in millions of dollars in lost revenue or delayed mission objectives. By compressing the lead time of critical structural elements to a matter of weeks, RWC is effectively de-risking the supply chain for its clients.

DPP Pultrusion’s leadership also emphasized the technical synergy of the partnership, noting that their high-strain stowable profiles are uniquely suited for the mechanical demands of deployable space structures. By utilizing premium raw materials and highly specialized resins, DPP ensures that structural elements can be tightly folded or stowed for launch and still deploy reliably in orbit without suffering from micro-cracking or permanent deformation.


Implications: The Future of Space Deployables and the COTS Revolution

The introduction of the STRATOPultrusion™ line has far-reaching implications for the design, manufacturing, and economics of future space systems.

Accelerating the COTS (Commercial Off-The-Shelf) Movement

For decades, the aerospace sector operated under the assumption that every satellite must be custom-built. The "NewSpace" revolution has challenged this notion by proving that using standardized, commercial-off-the-shelf (COTS) components can dramatically lower costs without sacrificing reliability. By bringing space-grade carbon fiber tubes and rods to an e-commerce platform, RWC is pushing the COTS philosophy into primary and secondary space structures.

Enabling Next-Generation Deployable Architectures

As satellites become smaller (CubeSats and MicroSats), the payloads they carry—such as solar arrays and high-gain antennas—must become highly compact. Deployable structures are critical to this effort. They must be stowed tightly within the launch vehicle’s fairing and then unfurl reliably once in orbit.

The high-strain capabilities and dimensional stability of the STRATOPultrusion™ products provide the perfect structural backbone for these mechanisms. This advancement is poised to benefit several key areas:

  • LEO Megaconstellations: Enabling rapid, high-volume production of identical satellite buses requiring standardized solar panel frames.
  • Deep Space Exploration: Providing ultra-stable, low-CTE boom structures for scientific instruments that must remain perfectly aligned across extreme temperature variations.
  • Defense and National Security Satellites: Allowing military space agencies to rapidly assemble and launch responsive space assets in reaction to geopolitical events.

By combining the continuous, high-efficiency manufacturing of pultrusion with the rigorous quality standards required for space flight, Rock West Composites and DPP Pultrusion have established a new benchmark for aerospace material procurement. As the 2026 Small Satellite Conference gets underway, the STRATOPultrusion™ line stands as a testament to how strategic partnerships and manufacturing innovation can help make the high frontier more accessible, affordable, and reliable.
