What would a suit-like protective garment weigh and cost, and what limits it?
research/garment-protective
Cunniff-style scaling for nylon, aramid and UHMWPE: at equal weight UHMWPE gives 1.49× aramid's V50 and needs 0.20–0.67× the areal density depending on an unknown exponent; a 3 mm, 1 kg suit-like panel falls short of a 4 kg/m² aramid reference except under optimistic assumptions. Stylised; recalled formula, assumed properties and prices, no protection claim.
What it found
A Cunniff-style specific-toughness scaling (U*) for nylon, aramid and UHMWPE with a 0.5 m2 torso-panel mass, cost, thickness and stiffness model. At equal weight UHMWPE gives 1.49× aramid's V50 in this scaling, and needs 0.20–0.67× the areal density depending on an unknown exponent. Under a 3 mm, 1 kg suit-like limit the panel falls short of a 4 kg/m2 aramid reference except for UHMWPE with an optimistic exponent. Stylised: recalled formula, assumed properties and unsourced prices, no ballistic physics and no protection claim.

- Which sensors in a smart garment recognise what you are doing, and how fragile is that to garment slip?Activity recognition from simulated chest/thigh/wrist IMUs and knee/elbow strain: two sensors reach ~99% and all five 99.9% on easy synthetic classes, but a clean-trained model falls to 45% under 1 rad garment slip (94% when trained with slip). Stylised; invented signals, no real dataset.
- Where does a designer coat's price go, and what does a $20 to $50 replica keep?Bottom-up cost model for a lined coat applied to two reported designer prices: modelled factory cost is under 15% of price, the assumed markup chain does not close the gap, and a $20–50 replica needs very cheap cloth and labour. All inputs assumed. Stylised.
- Can a cheap cloth drape score how well a flat pattern fits a body, and is a fitted pattern body-specific?Position-based cloth drape scores a flat skirt-tube pattern on two synthetic elliptical bodies by strain and waist ease; the best waist is near the body's waist perimeter and a pattern fitted to one body fits the other clearly worse. Stylised; strains depend on mesh and solver.
- How much cloth does marker making waste, and do annealing and exact methods beat greedy nesting?Marker making as strip packing: on 20 random 8-box markers, shelf heuristics leave 17–20% extra length vs the exact optimum, annealing 0.5%; on two stylised garments, polygon nesting beats box packing at equal budget. Stylised; no seam allowance or multi-ply.
- What do seam allowance and mixed sizes do to marker efficiency, and what does that do to a garment's cloth cost?A 1 cm seam allowance cut the stylised shirt's marker efficiency from 0.69 to 0.63 and the skirt's from 0.71 to 0.51; mixing three sizes in one marker shortened it 9%; swapped into the cost model, trench cloth rises from $26 to $33–41 at $7/m². Stylised; sensitivity, not a coat measurement.
- How much cloth does a cutting plan save by mixing sizes in one marker, and is the saving real?Cutting-order planning for a 3-size stylised shirt: laying several garments per marker saves 9–11% of cloth over one per marker; mixing sizes adds 0.4–3.7% in sample, but re-nesting the chosen markers with fresh seeds leaves +0.09%, so it is within nesting noise. Stylised; invented shapes.
