Manufacturing process

Resin transfer moulding

Also known as RTM, resin transfer molding

A closed-mould process in which resin is injected into a dry fibre preform clamped between matched mould tools. It can make continuous-fibre structural parts.

What Lithoen records

Each claim states how it is known and cites its evidence.

EstablishedContinuous-fibre structural parts; thermoset matrices.

Resin transfer moulding can make continuous carbon-fibre composites for structural and semi-structural parts, and it is used with thermoset matrices in natural fibre composites.

Evidence support: Supported by the cited evidence 2 sources, multiple sources, independence unknown

Evidence: U.S. Department of Energy 2015 Primary authority; L. 2016 Peer-reviewed

EstablishedExpensive matched tooling, smaller parts, risk of dry spots.

Matched tooling able to withstand resin transfer moulding pressures is expensive and generally limited to smaller components, and areas the resin fails to impregnate cause costly scrap.

EstablishedResin injected into a dry preform clamped between matched mould tools.

In resin transfer moulding a dry fibre preform is packed into a mould tool shaped like the part, a second tool is clamped over it, and resin is injected into the closed cavity, sometimes with vacuum assisting the flow.
