Application

Design takeaway

When designing with polylactide/cellulose fibre biocomposites for vehicle interiors, consider optimizing compounding processes and explore the use of absorbent additives to control odour.

How to apply

When selecting or developing biocomposite materials for enclosed environments like car interiors, evaluate the impact of processing on odour and consider incorporating odour-absorbing additives.

Project actions

01When researching materials for your design project, consider their potential for odour emission, especially for interior applications.
02Investigate additives that can improve material performance or reduce undesirable characteristics like odour.

Method & Evidence

AimTo investigate the impact of processing stages and absorbent agents on the odour emission and properties of polylactide/cellulose fibre biocomposites for automotive interiors.

MethodExperimental characterisation and material testing

ProcedureBiocomposites were prepared and subjected to various processing stages (drying, compounding, injection moulding). Material properties were analysed using size exclusion chromatography, thermogravimetry, and differential scanning calorimetry. Odour emission was quantified using dynamic dilution olfactometry and the Field of odours method. The effect of an absorbent agent was evaluated.

Variables

IV["Processing stages (drying, compounding, injection moulding)","Presence/absence of absorbent agent"]

DV["Polylactide degradation (molecular weight)","Odour emission (global odour concentration)","Material properties (morphology, mechanical, thermal)"]

CV["Biocomposite composition (polylactide/cellulose fibre ratio)","Specific absorbent agent used","Testing conditions for material characterisation and olfactometry"]

Strengths & Limitations

Strengths

+Comprehensive characterisation of material properties and odour emission.
+Direct comparison of processing stage impacts.
+Demonstration of a functional solution (absorbent agent).

Limitations

The specific absorbent agent used might not be readily available or cost-effective for all design projects. The study's focus on automotive interiors may limit direct applicability to other domains without further adaptation.

Reliability & validity

The use of established analytical techniques (SEC, TGA, DSC) and standardized olfactometry methods contributes to the reliability of the findings. Validity is supported by the direct correlation observed between processing, material changes, and odour emission.

Think critically

To what extent can odour be considered a primary performance metric in material selection, and how might this influence the adoption of otherwise sustainable materials?

Design Principles

"Material formulation and processing can be tailored to mitigate undesirable emissions without sacrificing performance."

This research offers a practical solution for designers and engineers developing interior automotive components from biocomposites. By mitigating odour, manufacturers can enhance user experience and meet increasingly stringent automotive interior air quality standards, promoting the adoption of more sustainable materials.

What This Means for Your Design

Making car parts from plant-based plastics can sometimes smell bad. This study found that how you mix the materials (compounding) is the main cause of the smell. Adding a special ingredient can cut the smell in half without making the part weaker.

How to use in your project
