Record Breaking Agera R Hypercar Manufactured Using Umeco’s Prepregs

The Koenigsegg Agera R Hypercar, using Umeco’s lightweight prepregs to minimise overall vehicle weight, has broke the existing Guinness Book of World Records title for ‘The fastest time for a two-seater production car to travel from 0-300-0 km/h’, which it achieved in just 21.19 seconds.

Umeco explain that the application of their lightweight prepregs for the structure, bodywork and cosmetic trim all contributed to the record-breaking performance of the hypercar. Umeco’s BPS240 body panel system is used for the bodywork, MTM57 prepreg for internal and external cosmetic trim, and MTM58FRB prepreg for the chassis, under-bonnet parts and ancillary structural components. They say the Agera R is the amalgamation and application of lightweight products developed in a partnership between Koenigsegg and themselves.

According to Umeco, the Agera R is the continuation of a long-standing, mutually-beneficial association, and the product of Koenigsegg’s design and manufacturing expertise. It follows on from their supercars, the CCR and CCX models.

Umeco says their BPS240 composite carbon fibre prepreg body panel system is being used for the body panels of the Agera R. BPS240 is their two-part, partially-impregnated epoxy prepreg system specifically designed for car body panels. They say BPS240 provides excellent surface quality from vacuum-only or press mould processing. The first ply, which utilises Umeco’s ZPREG partial impregnation technology, consists of a structural fabric coupled to a surface scrim by a high performance resin system. The second ply combines a low density syntactic core material and a structural fabric to create significant panel rigidity in a rapid laminating format. The system is designed to be ready for painting without additional surface rework. In many cases, paint is applied directly to a degreased panel. Umeco claim that excellent environmental performance is achieved from panels painted in low-bake and hi-bake paint systems.

Koenigsegg explain that they use Umeco’s MTM57 to achieve the superior surface finish on the Agera R’s interior and exterior cosmetic trim panels. MTM57 exhibits excellent toughness and can be processed using autoclave, vacuum-only and press mould processing.

Koenigsegg explain they built the Agera R’s chassis, under-bonnet parts and ancillary structural components from Umeco’s MTM58FRB prepreg to provide required handling characteristics. Umeco explain this is a black pigmented, flame-retarded, 120°C curing epoxy prepreg matrix specifically developed for component manufacture. It is suitable for autoclave, vacuum-only and press moulding processing, and is self-extinguishing and flame-retarded, meeting the requirements of FMVS302/ISO3795 and FAR25.857.

Koenigsegg also uses Umeco’s master model materials and LTM12 tooling prepregs for all main production parts on the Agera R. Fully compatible with Umeco’s component prepregs, LTM12 is a low temperature cure prepreg which may be used to produce composite tooling direct from low temperature master models. Umeco say that following a suitable, free-standing post-cure, LTM12 tooling can be used at temperatures up to 200°C.
