Non-woven laid scrims for Automotive Undershields

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 undershields​ — the non-woven / GMT / PP-backed panel mounted beneath the engine bay and along the underbody to deflect stones, spray, and road debris while contributing to NVH damping and aerodynamic smoothing. 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 undershield 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- and heat-tolerant composite that survives stone impact, underbody wash, road-salt exposure, and thermal/ vibration cycles (-40 °C to >120 °C near exhaust/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 underbody and engine-bay 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.

The First and Biggest manufacturer and supplier of laid scrims in china!

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.
