Non-woven laid scrims for Automotive Outer wheel arch liners

Non-woven laid scrims Introduction

This product is a Laid Scrim​ (glass, polyester, or hybrid), a cost-effective, open-mesh reinforcement fabric engineered for automotive outer wheel arch liners​ — the non-woven / GMT / PP-backed shield that sits ahead of or behind the wheel arch to deflect stone chips, mud, and spray. It is manufactured by chemically bonding continuous filament yarns (Glass, Polyester, Carbon, Cotton, Flax, Jute, Viscose, Kevlar, Nomex, etc.) into a flat-laid open mesh (square or tri-directional), then laminated into or between the non-woven / GMT / PP stack that forms the arch liner substrate. Thanks to lightweight, high strength, low shrinkage/low elongation, and corrosion resistance, the scrim upgrades a limp or brittle substrate into a dimensionally stable, impact-tolerant composite that survives stone-chip impact, mud slurry wash, road-salt exposure, and NVH vibration/thermal cycles (-40 °C to >100 °C near the brake/engine zone). 

Non-woven laid scrims Characteristics

Non-woven laid scrims Application

Primary Use: Reinforcement for Automotive Undershields

The core application of this automotive-grade laid scrim is as the hidden tensile grid laminated into or between​ the non-woven / GMT / PP stack that forms the underbody shield — and by extension the same scrim platform also serves rear shelves, headliners, door-linings, seat-back trims, outer wheel-arch liners, engine casing / sound-deadening, foams punched parts​ within the same Automotive category. It is laminated into the host stack to:

Add Stone-Impact & Underside Abuse Resistance

Undershields take constant gravel impact, road-salt spray, and occasional bottoming. The scrim adds multi-directional tensile and tear resistance at very low GSM, reinforcing the non-woven/GMT sandwich without thickening the tray or adding molded-in stress risers around clip/fastener bosses.

Maintain Dimensional Stability Through Exhaust-Zone Cycles

The scrim’s low elongation keeps the undershield flat through press-forming, trimming, and road cycles (-40 °C to >120 °C near exhaust/engine zone, NVH vibration, car-wash / chassis-dyno loading), preserving fit against the underbody and preventing rattle or aeroshield flutter.

Enable Lightweighting & NVH Goals

With glass, carbon, or hybrid scrim options, the same non-woven/GMT stack can be down-gauged while holding strength — supporting OEM lightweighting and NVH damping strategies for exterior and interior trim programs.

Secondary Applications

a) Aluminum Foil Composite

b) PVC Flooring

c) None-woven category products reinforced

d) PVC Tarpaulin

Laid scrim can be used as basic materials to produce truck cover, light awning, banner, sail cloth​ etc.

Due to lightweight, high strength, low shrinkage/elongation, corrosion preventive, laid scrims offers tremendous value compared to conventional material concepts. And it’s easily to laminate with many kinds of materials, this makes it has an extensive fields of applications.
