PROPERTIES

Based on three optimization cri-teria which are

properties (weight, stiness,strength)

price

sustainability

we support you to design theoptimal sandwich structure

(choice o materials, laminateplan etc.).

The result is a sustainable pro-duct design that has superiortechnical properties at opti-mized cost.

Unique about our Hybrid CoreConcept is the denition o asustainable sandwich design.

How can you get to that? Thekeyword in this context is Lie

Cycle Analysis.A Lie Cycle Analysis (LCA)shows the total environmentalimpact o a product through-out the dierent phases o aproducts lie cycle. Each phaseo the lie cycle consumes

resources and may generatereusable output (recycling).

The sum o all input minus allreusable output is the environ-mental ootprint o a product.

On the reverse side o this fyeris an optimization example oran upper foor section o adouble-decker bus. It illustrateshow the environmental ootprinto a structure can be improvedthanks to our Hybrid Core Cal-culator.

Example: Optimization oan upper foor section o adouble-decker bus

Facts and gures:

Double-decker city bus

Lie time mileage 800000km

Fuel consumption 40lt/100km

End-o-lie scenario Recycling

Total bus weight 15t

Steel upper foor 560kg

Alternative sandwich foor ap-prox. 360kg

Dimensions o upper foor sec-tion:

Length 11.2m

Width 2.4m

The chart below shows the

greenhouse potential or severaldesign options.

The most critical impact is theuse phase which is driven byweight.

This means that or a typical citybus the impact o the dierentcore materials is minor com-pared to the use phase impact.

In comparison to the steel foor,a sandwich design can reducethe foors weight by some 30%.

The chart also shows that in thisuse-phase-intensive applica-tion this weight reduction resultsin a considerable 30% reductiono the foors ecological impact.

A composite sandwich construc-tion is thereore not only lighterbut also much more sustainable.

Key insights:

The lie cycle analysis alwayscomprises the total lie o a

product rom cradle (produc-tion) to grave (end-o-lie).

Each application has to beanalyzed in its specic cir-cumstances, especially regar-ding the use phase and theend-o-lie scenario.

I the use phase is energy-intensive, the ecological im-pact o production, transport,end-o-lie may become negli-gible. In such application, lightweight and energy eciency

are key drivers.

Depending on the point oview (energy, CO

2equ., water

usage, ocus on end-o-lie,etc.), dierent material selec-tions may be avorable.

Every kg o a product:

uses raw materials

needs to be transported

may consume energy duringthe products use phase(bus)

requires incineration/ land-ll/ recycling

Every kg o a product that canbe saved improves a productsecological ootprint.

The ecological ootprint

o the bus foor can bereduced by 30%!
