Design takeaway

When designing with composite materials, prioritize reducing the amount of resin used, as it has a disproportionately higher environmental impact compared to reinforcing fibers.

How to apply

When designing composite products, conduct an LCA to identify the components with the highest environmental impact and explore design modifications to reduce their proportion or substitute them with lower-impact alternatives.

Project actions

  • 01When choosing materials for your design, consider their environmental impact beyond just performance and cost.
  • 02Think about the entire lifecycle of your product, from raw material extraction to disposal.

Method & Evidence

AimHow can the resin content in composite ship structures be optimized to minimize environmental impact, specifically global warming and ozone depletion potentials, during the production and use phases?
MethodComparative Life Cycle Assessment (LCA)
ProcedureA 52-ft. yacht's composite structure was redesigned for reduced weight. Life Cycle Assessments were conducted on both the original and lightweight designs using SimaPro 8, analyzing impacts during production and a 20-year use phase. The environmental impact of glass fiber and resin components were individually assessed.

Strengths & Limitations

Strengths

  • +Employs a recognized methodology (LCA) for environmental assessment.
  • +Provides a quantitative comparison of environmental impacts between different design iterations.

Limitations

Performing a full LCA can be complex and data-intensive. The accuracy of the results depends heavily on the quality of the data used.

Reliability & validity

The reliability of the LCA depends on the consistency of the SimaPro database and the accuracy of the input data. Validity is supported by the comparative nature of the assessment, focusing on relative changes.

Think critically

To what extent can the findings regarding resin impact be generalized to other composite materials and applications beyond marine vessels?
