Introducing Evopreg® EPC205 epoxy prepreg system

Introducing Evopreg® EPC205 epoxy prepreg system, a new thick laminate technology from Composites Evolution for use in component manufacture.

A visual-quality epoxy component prepreg for laminates up to 50 mm thick has been
developed by Composites Evolution. It can be cured in a single shot using a conventional
autoclave or press curing technique, with a low risk of exotherms. The material is readily
available and, like all other materials in the Composites Evolution EPC series, has durable
handling and excellent tack properties.

Evopreg® EPC205 epoxy component prepregs can be used in a wide variety of markets and
applications, including inserts, furniture, sporting goods, sculptures, and structural repairs.
Technical Specialist, Roger Elliott explains further:

“Historically, composite inserts have been laminated in flat sheets, bonded together to create
thick laminates, and then machined to the necessary surface profile. Using EPC205, thick
laminates can be laminated over contoured moulds to the desired thickness and cured in a
single shot cure.”

“With the use of EPC205, inserts can be designed with the optimum shape, thickness and
composite structure, as well as providing a solid laminate for attachments and mechanical
fasteners. This process results in a decrease in production time and cost as well as an
improvement in the mechanical properties of the insert because bond lines are eliminated.”

Jonathan Coyney, Penta Patterns, Composite Leader, commented: “EPC205 has great
workability and provides a visual surface finish to match.”

Adam Smith, Karma Composites, Director, added “Karma Composites was able to create a
bespoke thick section tool in a single shot whilst achieving all the necessary mechanical
properties which would have been challenging to accomplish with a different resin system.”
