EnergyCFRP Pultruded Spar-Cap Laminate for Wind Blades — Static Characteristic Values per DNVGL-ST-0376
WE-C100 is F1 Composite's unidirectional carbon / epoxy pultruded laminate for the spar caps of long wind blades. The article walks the full static mechanical data (tension, compression, shear, flexure, ILSS) and explains how the DNVGL-ST-0376 characteristic value Rk differs from the panel average, and why blade designers must build the layup on Rk rather than the mean.

Material InnovationThe Surface Finish Question — How Transverse-Reinforced Pultrusion Removes Glass-Fiber Telegraph from FRP Window Profiles
Why premium architectural fenestration still chooses aluminum over fibreglass, and how a transverse-reinforced pultrusion architecture buries cross-direction reinforcement deeper to deliver powder-coat finishes indistinguishable from aluminum.
FenestrationPowder-Coated FRP Window Profiles: How to Get an Aluminum-Grade Finish with Superior Thermal Performance
Pultruded FRP window profiles can now achieve the same sleek, metallic finish as aluminum frames through architectural-grade powder coating — without sacrificing the thermal insulation, corrosion resistance, and dimensional stability that make fiberglass window frames superior.
SustainabilityThermoset FRP Is Now Recyclable: How Chemical Degradation Recovers Glass Fibers and Resin
Thermoset FRP composites were long considered non-recyclable. A new chemical degradation process dissolves cured polyester and vinyl ester matrices at just 100 °C, recovering clean glass fibers for reuse and reclaiming the solvent in a closed loop.

How do pultruded FRP profiles behave in fire? This guide explains the fire-resistance mechanisms of fiber reinforced polymers, the role of resin chemistry and flame-retardant additives, classification standards from Euroclass to ASTM E84, and where fire-rated FRP is already deployed.
Material SciencePultruded FRP vs Steel, Aluminum, PVC, and Wood: Impact Resistance Under 3-Point Bending Drop Test
A 3-point bending drop test by Covestro's polyurethane research team puts seven materials head-to-head: sheet steel, stainless steel, two aluminum alloys, PVC, plywood, and polyurethane pultruded composite. The results reveal why FRP's unique combination of toughness and elastic recovery outperforms every conventional alternative.
Market AnalysisGFRP Fenestration Passes AS 2047: What It Means for the Australian Window and Door Market
Two pultruded GFRP fenestration systems — an 80 Series turn-and-tilt window and a 140 Series lift-sliding door — have passed full AS 2047-2014 compliance testing by Intertek. With all tests cleared for wind pressure, air infiltration, water penetration, and ultimate strength, glass fiber reinforced polymer is now a code-compliant fenestration material for the Australian construction market.
Lifecycle AnalysisWhy Pultruded FRP Profiles Are Replacing Steel in Coastal Infrastructure
