The art of shaping composites.

Composite compositions

A composite material is something of a paradox. It uses at least two different substances (like glass fibre and resin) to make a new material. The new material is more than just a combination of the individual materials’ strengths – it is exponentially better, with desirable properties like low weight, low cost and high strength.
As a partner in your development process, we offer technologies of the highest quality and economy.

 

 

By specializing in high-strength lightweight components for vehicle fabrication, we have built up a great fund of knowledge in the development and production of composite parts. We are also experts in the process- and mould-integrated finishing of surfaces using foil or in-mould coating techniques.

1
Sheet Moulding Compound (SMC) Lightweight and multi-use

Resistance to chemical agents and temperature changes, high dimensional stability and Class A surface quality characterize components made with SMC. Fritzmeier masters the whole SMC technology spectrum and uses it to make components for trucks, cars and agricultural machines. The production options include direct coating processes like IMC (In-Mould Coating) or IPC (In-Mould Powder Coating), as well as the online bonding of 2-shell thin foil parts.

Sample products:
Wind deflectors, front hatches, rear hatches, tractor roofs

Sandwich Monocoque Injection (SMI) All in one

The development of the SMI process represents a milestone in the Fritzmeier Composite success story. Based on the RTM process, this technology meets the challenges of light weight, functionality and economy. Its special advantage lies in the fact that it sandwiches materials into unitary, one-piece components. For composite roofs, for example, this completely eliminates the need for expensive inside panelling and insulation installation.

Sample products:
High roofs, wind deflectors, floor groups

Long Fibre Injection (LFI) High rigidity with smaller wall thickness

As a specialist in composites for vehicle construction, we immediately recognized the technical and economic advantages of this technology. The direct processing of fiberglass rovings with rigid polyurethane foam systems offers a high material quality level and is particularly suitable for larger structural parts. Maximum use of the technology’s potential is achieved by back-foaming deep-drawn rigid foils. This obviates costly painting work and the logistics required for it, while giving excellent surfaces.

Sample products:
Roof storage systems, roofs, panelling parts

Structural Reaction Moulding (SRM) High-end interior parts

This technology is used by preference for making parts that will be subjected to high structural loads or must fulfil special requirements with respect to dimensional accuracy and stability. By back-foaming decorative foils, high quality surfaces are created very economically in just one process.

Sample products:
Interior panelling parts, roof storage systems, panelling parts, instrument panels, structural parts

S-RIM (Structural RIM) and MM-RIM (Mat Moulding RIM) are versions of RIM used when the reaction mass is moulded around a reinforcing structure.

Fritzmeier RTM Fertigung
Resin Transfer Moulding (RTM) Top performance at high volumes

The RTM resin injection process has established itself as the preferred technique for flat components with long or endless fibre reinforcement. Only high-quality epoxy resin systems and glass or carbon fibre are used here.

Sample products:
CFK chassis structural parts, GFR structural parts

Wet Pressure Moulding (WPM) The economical alternative

In recent years wet pressure moulding has had something of a renaissance, with an automated and fully integrated process line with high process stability and short cycle times. A robot applies the resin to the web complex outside the press, while another places the impregnated stack in the press. At mould temperatures over 130°C curing can take as little as 90 seconds.

CFK chassis structural parts, GFR structural parts
