Description

Т26 is a single part low viscosity epoxy infusion resin, coated with UD tape, developed for high-loaded structures. T26 offers simple and flexible processing due to low viscosity at relatively low impregnation temperatures (110°С). T26 was developed specially for RTM and vacuum infusion molding, to produce laminates with low porosity and extremely high mechanical performance, especially in crack resistance. It shows the following features and properties:

One-part resin designed specifically for high-temperature infusion or RTM

Wide processing window > 7 hours at 110°C

Curing at 180°C provides glass transition temperature of 205°C

High wet glass transition temperature —172°C

Very high resistance to impact

Operating temperatures from –60°C to 150°C

Technological properties

Property
Application areas	Drones;Sports equipment: Frame, wheels, seat, seat post, handlebar, head stem and crank arm of a sports bicycle are made of carbon composite;Geometry strengthen elements: Experimental stringer panel
Processing history	Samples for testing were obtained by vacuum infusion based on T26 resin and UD tape covered by veil 11424 (200 g/m2, 12K, 4.5 GPa/240 GPa).
Processing methods	Preheat the resin to 60-90°С in its container for transfer to the resin pot. Degas the resin for 30-40 minutes while heating to 90°С. Preheat the tool to 100-110°С (or to 115-120°С for parts having complex shape or for UD parts). Maintaining resin pot temperature of 95 °С and tool temperature of 100-115 °С, begin resin infusion. After complete impregnation increase tool temperature at 2°С/min to 180°С. Dwell at 180°С for 3 h. Cool the tool to 90°С at <5°С/min before releasing part from tool.
