Fiberglass Reinforced Sheets

Fiberglass reinforced sheets combine two structural fiberglass skins with a lightweight honeycomb core, creating panels that deliver exceptional strength-to-weight ratios. The outer skins use epoxy-impregnated woven fiberglass fabric, while the core features hexagonal cells made from aramid paper, polypropylene (PP), or aluminum honeycomb.

Manufacturing involves sandwiching the core between fiberglass layers, then consolidating through high-temperature curing or thermal lamination. This process bonds all components into a cohesive panel with high tensile and compressive strength. The separated skin design provides significant stiffness and dimensional stability while maintaining low thermal expansion.

These panels excel in aerospace interior components, marine hull reinforcements, transportation applications, and architectural cladding. The hollow core structure inherently provides sound deadening and thermal insulation properties, while the fiberglass construction resists moisture, corrosion, and chemical exposure.

Customization spans thickness ranges from 10mm to 75mm, with widths up to 3.2 meters and lengths reaching 12 meters. Panels accommodate Computer Numerical Control (CNC) machining for precise cutting and drilling, and work with standard carbide-tipped tools. Surface treatments range from high-gloss to textured finishes, with extensive options for core density, cell size, and dimensional specifications.

CFRT Sheets

A high-performance composite sheet made of continuous fiber reinforcements (such as glass or carbon) fully impregnated in a thermoplastic matrix. This construction provides exceptional stiffness, high strength, and impact resistance in a lightweight, thermoformable, and fully recyclable material form.

FR4 Fiberglass Sheets

A high-pressure thermoset laminate composed of woven glass fabric with a flame-retardant epoxy resin binder. It is defined by its high mechanical strength, excellent electrical insulating properties, and low moisture absorption, maintaining these characteristics in both dry and humid conditions.

FRP/GRP Sheet

Fiberglass reinforced plastic composite sheet made of glass fiber reinforcement and polymer resin matrix. Offers exceptional strength-to-weight ratio, corrosion resistance, UV stability, non-conductive properties, and dimensional stability for industrial, marine, construction, and chemical-resistant applications.

LWRT Sheets

A lightweight reinforced thermoplastic material made from a non-woven mat of commingled glass and polypropylene fibers. Its defining characteristic is a low-density, porous structure that provides excellent sound absorption and thermal insulation properties, combined with high impact resistance and structural integrity.

Thermoplastic UD Tapes

A continuous fiber reinforced composite in a thin, tape-like format where all fibers are aligned in a single direction. This unidirectional alignment provides extremely high tensile strength and stiffness precisely along the fiber axis, delivering optimized, load-bearing performance in a specific orientation.

Fiberglass Reinforced Sheets Selection & Engineering Guide

Selecting the right specification for Fiberglass Reinforced Sheets depends on matching structural load requirements, environmental exposure, and thermal R-value insulation goals. At RaxPanel, our engineering team manufactures high-performance composite panels to deliver durable, moisture-resistant, and energy-efficient solutions for industrial and commercial projects worldwide.

💡 Pro Tip: Delamination Prevention Under Thermal Cycling
At RaxPanel, we utilize automated vacuum lamination with high-performance two-component polyurethane adhesives to ensure a bond strength that absorbs differential thermal expansion without micro-delamination.

1. How to Choose the Right Skin Alloy and Thickness

Outer skin selection governs mechanical impact resistance, corrosion barriers, and structural stiffness across different operating environments.

2. How Well Does the Core Insulate and Withstand Heavy Loads?

The core material handles shear stress and maintains thermal R-value insulation across operating temperature ranges:

Performance Metric	RaxPanel Engineering Standard	Application Advantage
Outer Skin Spec	Pre-Painted Aluminum / GRP Sheet (0.3mm – 2.0mm)	High tensile strength and corrosion resistance
Thermal Conductivity	~ 0.020 – 0.038 W/m·K	Consistent R-value insulation & energy savings
Bonding Adhesive	Two-Component Polyurethane / Epoxy Adhesive	Delamination-free performance under freeze-thaw cycles

3. Which Surface Finish Will Protect Your Panels for 20+ Years?

Factory roller coating specifies long-term color stability, UV protection, and resistance against industrial pollutants or marine salt spray.

4. How Fire-Safe and Soundproof Are These Panels?

🛡️ Compliance & Acoustic Isolation:

Fire Safety: Formulations comply with EN 13501-1 Class B-s1,d0 and GB8624 Class B1 building fire safety standards.
Sound Damping: Composite core attenuates noise transmission by 24 dB to 30 dB relative to solid metal sheets.

5. Where Are Fiberglass Reinforced Sheetss Most Commonly Installed?

🏢 Commercial & Industrial Buildings

Exterior wall cladding, cleanroom partitions, and insulated roof envelopes.

🚚 Cold Storage & Transport Fleets

Refrigerated truck bodies, cold storage rooms, and RV composite walls.

6. How to Cut, Groove, and Seal Edges During Installation

Panels process easily on-site using standard CNC machinery, routers, or specialized edge profiles for airtight moisture sealing.

Frequently Asked Questions (FAQS)

1. What are the standard panel thicknesses, maximum lengths, and width options available for Fiberglass Reinforced Sheetss?

Standard panel thicknesses range from 10mm up to 150mm. Standard widths include 1000mm, 1220mm, and 1500mm, with maximum single-sheet lengths up to 5800mm (5.8m) to fit ocean freight container shipping dimensions.

2. What are the primary engineering benefits of using Fiberglass Reinforced Sheetss?

Fiberglass Reinforced Sheetss deliver an exceptional stiffness-to-weight ratio, rot-proof moisture resistance, reliable thermal insulation, and dynamic fatigue endurance for high-stress applications.

3. How do these composite panels perform under high humidity and outdoor weathering?

The closed-cell core prevents water logging and condensation absorption, while pre-painted skins provide a 20+ year weatherability barrier against UV degradation.

4. What fire safety ratings and quality certifications do these composite panels meet?

Flame-retardant formulations meet EN 13501-1 Class B-s1,d0 and GB8624 Class B1 fire performance standards. Manufacturing quality is governed under ISO9001 management systems, with raw material performance verified under SGS and CE testing.

5. What surface coating options are available for exterior UV protection?

70% PVDF Fluorocarbon Coating PVDF coating provides a 20+ year exterior weatherability warranty against UV fading and acid rain. FEVE offers high gloss retention, while PE coating is cost-effective for indoor partitions.

6. Can these composite panels be CNC grooved, bent, or edge-sealed on-site?

Yes. Pre-painted skins can be V-grooved at 90° or 135° on the reverse side using standard CNC routers or hand tools, allowing manual edge folding into architectural cassettes without surface paint cracking.

7. How are large panel shipments packaged to prevent freight damage during ocean transit?

Panels are packed with protective PE film on both skins, separated by inter-sheet foam layers, and secured on heavy-duty export wooden pallets or CKD steel crates to prevent shipping damage during 20ft and 40ft container freight.
