Structural composites, engineered to endure.
PROA is an independent composites engineering practice based in Aveiro, Portugal. We provide structural analysis and design for aerospace, automotive and defence programmes — from first concept through to a certified, manufacturable part.
Analysis-led design
Every design decision is grounded in structural substantiation, not the other way around.
Certification in mind
Test and substantiation strategy considered from concept, not bolted on at the end.
Built to grow
Operating today as a design office, with manufacturing capability planned as the practice grows.
SERVICES
A practice built around the full structural lifecycle
Six stages, from application to a manufacturable part.
Project setup & application
Concept design
Structural analysis
Prototyping
Testing planning & route to certification
Design for manufacturing
ABOUT
A practice at the front of the structure
PROA was founded in Aveiro by a structural composites engineer with five years of experience analysing primary and secondary structures across aerospace, automotive and defence programmes in the UK.
The name comes from the Portuguese word for the bow of a boat — the part that takes the load first, sets the course, and is built to endure it. That's the position PROA is built to take: at the front of a structure, and at the front of a programme.
We currently operate as a design and analysis office — deliberately structured to move fast and stay close to every project — with manufacturing capability planned as the practice grows.

SERVICES
From first application to a manufacturable part
PROA supports programmes across the full structural lifecycle, engaged for a single stage or end to end.
Project setup & application
Scoping, requirements capture and proposal support to get a programme started on the right footing — clarifying loads, standards, and the certification basis before design work begins.
Concept design
Early-stage architecture and material selection studies that explore structural options and trade-offs before committing to a configuration.
Structural analysis
Static, fatigue, buckling and damage-tolerance analysis substantiating primary and secondary composite structures, including detailed hand and FE-based methods.
Prototyping
Design support through the build of prototype and demonstrator parts, bridging the gap between concept and physical test.
Testing planning & route to certification
Test programme definition and substantiation strategy aligned with the applicable certification basis, from coupon level through to full-scale test.
Design for manufacturing
Translating a qualified design into a producible, repeatable manufacturing definition — tooling concepts, lay-up sequence, and process specification.

Damage tolerance in bonded composite joints: a practical primer
Why damage tolerance, not just static strength, tends to drive the sizing of bonded composite joints — and what that means early in design.
READ
Why damage tolerance, not just static strength, tends to drive the sizing of bonded composite joints — and what that means early in design.
Placeholder article. Bonded composite joints are efficient load-transfer solutions, but their structural substantiation is rarely governed by static strength alone. Damage tolerance — the ability of a joint to carry design loads in the presence of disbonds, delaminations or impact damage — is frequently the dominant driver, particularly once inspection intervals and detectability thresholds are factored in.
This placeholder is a stand-in for a real article: a short walkthrough of how a damage-tolerant bonded joint is typically approached, from assumed flaw sizes through to residual strength substantiation, would sit well here.
Choosing between NASTRAN and ABAQUS for early-stage sizing
A practical comparison for structures engineers deciding which tool to reach for at the concept and preliminary sizing stage.
READ
A practical comparison for structures engineers deciding which tool to reach for at the concept and preliminary sizing stage.
Placeholder article. At concept and preliminary sizing stage, the right analysis tool is often less about raw capability and more about iteration speed, model reuse, and how easily results translate into a sizing margin.
Replace this placeholder with a genuine comparison drawn from real project experience — for example, when a fast linear-static NASTRAN model is enough, versus when ABAQUS's nonlinear and progressive-failure capability earns its extra set-up cost.
