Comparing prices, lead times and supplier offers on a consistent basis.
Translating your needs into clear criteria and suitable options.
Prepregs are reinforcing fibres — such as carbon or glass — pre-impregnated with a precisely controlled amount of resin.
Stacked in layers and cured under heat and pressure, they become composite parts with an exceptional strength-to-weight ratio and great design freedom.
A carbon-fibre composite is roughly five times lighter than steel by density, while delivering comparable or higher strength.
Outstanding strength-to-weight and stiffness-to-weight ratios.
Complex shapes and properties tuned to the load path.
Resistant to corrosion, fatigue and many chemicals.
Controlled resin content gives repeatable, reliable results.
| Carbon prepreg | Glass prepreg | Aluminium | Steel | |
|---|---|---|---|---|
| Density, g/cm³ | ~1.6 | ~1.9 | 2.7 | 7.85 |
| Corrosion resistance | High | High | Medium | Low |
| Complex shapes | Easy | Easy | Limited | Limited |
A composite laminate is built from thin plies of resin-impregnated fibres. Orienting the plies at different angles — for example 0° and 90° — tunes strength and stiffness to the loads the part will carry.
Prepregs deliver exceptional strength-to-weight ratios and design freedom in a wide range of sectors.
Lighter wings, fuselage panels and launch-vehicle components for better fuel efficiency and structural integrity.
High-strength body panels, structural monocoques and EV battery enclosures that cut weight and extend range.
Wind-turbine blades, pressure vessels and lightweight structures for renewable and offshore energy.
Radiolucent imaging tables, prosthetics and orthotics where low weight and precision matter.
Optimised stiffness, flexibility and impact resistance in bicycle frames, skis, rackets and golf shafts.
Lightweight structural components and enclosures for security and defence applications.
Expert guidance on how composites can work in your business — from the first idea to a material that performs in your product.
Choosing the right fibre, resin system and prepreg format for your performance, cost and processing needs.
Assessing where composites can replace metals or other materials in your product and what that brings.
Laminate design, ply orientation and structural analysis to match the part to its real loads.
Advice on curing, lay-up and manufacturing processes to improve quality and reduce cost.
Composite materials market analysis: assessment of manufacturing capacity, demand volumes and patterns, and growth prospects across Europe and worldwide.
We help companies promote composite materials and finished products by translating technical advantages into clear customer benefits. We define target industries and audiences, product positioning, key messages and effective communication channels.
