Composite Semi-Trailers

Background

Road transport is by far the most important form of transport for goods in Europe and is expected to grow 25% over the next 15 years. This growth is in conflict with the environment because 87% of all good and freight are transported by road utilising heavy goods vehicles (in particular semi-trailers), which account for 10% of the total energy consumption in Europe and contributes to over 30% of the total CO₂ emissions.

Heavy goods vehicles are also known to cause damage to the infrastructure such as roads and bridges. Therefore, as vehicle weight/inertia accounts for a significant proportion of fuel consumption and CO₂ emissions, the use of lightweight materials and construction techniques are becoming increasingly important.

Solution

EPL in collaboration with VT Halmatic, University of Nottingham and Leyland Technical Centre (LTC) have recently concluded a 3 year research project (Roadlite) to develop a lightweight fibre reinforced composite semi-trailer.

The 10 metre composite semi-trailer is 25% lighter and 20% stiffer than an equivalent steel trailer and has performed very well in evaluation trials.

Benefits

The composite semi-trailer has been designed to be used as a flatbed, curtain or boxed trailer.

The internal structure can be tailored to maximise weight saving for both 'weights out' (ie 25% weight reduction) or 'volume out' (ie 45% weight reduction) applications.

The trailer design is 'modular' which enables semi-trailers to be customised and manufactured in different lengths from 7 metres to 13.6 metres.

Other benefits include:

• Excellent corrosion resistance and durability
• Increased aerodynamics from moulded shape
• Can accommodate single and multiple axle configurations
• Excellent road handling
• Economic – pay back within 2 years

Commercialisation

EPL are looking for industrial partners to assist with the commercialisation of this technology.
