This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Fillers include the following:

particulate materials which can be added to the composite matrix to vary the bulk, stiffness, density or other properties of the final composite

Requirements of core include the following:

stiffness/flexibility

directionality

density

shear strength

operating temperature

provision of thickness

provision of some rigidity

thermal and acoustic insulation, where appropriate

but not the significant structural strength provided by reinforcing

Most appropriate core/filler includes the following:

compliance with product requirements

greatest ease of use in manufacture

best financial return

greatest sustainability contribution

Areas for improvement include one (1) or more of the following:

cost/benefit of different core/filler systems

selecting a core/filler suited to the fabrication process

air/vapour entrapment

bonding/delaminating

contamination

Sustainability includes the following:

survival of the ecology/physical environment

economic viability

social sustainability
