Basalt Fiber Fabric vs. Basalt Fiber Needle Mat

Both Basalt Fiber Fabric and Basalt Fiber Needle Mat are insulation and reinforcement materials made from basalt rock fibers, but they differ significantly in structure, properties, applications, and performance.

1. Structure and Manufacturing

Aspect	Basalt Fiber Fabric	Basalt Fiber Needle Mat
Structure	Woven textile (plain, twill, satin)	Non-woven, felt-like mat
Production Method	Woven from continuous basalt yarns	Made by needling short basalt fibers into a mat
Fiber Type	Continuous fibers	Short/staple fibers

2. Physical & Mechanical Properties

Property	Basalt Fiber Fabric	Basalt Fiber Needle Mat
Strength	High tensile strength	Low tensile strength
Density	Lower bulk density	Higher bulk density
Flexibility	Good flexibility and drapability	Soft but bulkier, less form-fitting
Thermal Resistance	Up to ~800°C	Up to ~800°C
Acoustic Insulation	Moderate	Excellent
Vibration Dampening	Low	High

3. Applications

Industry/Use	Basalt Fiber Fabric	Basalt Fiber Needle Mat
Composites (e.g., automotive, aerospace)	Yes – used in laminates, FRPs	No, not structural
Thermal Insulation	Limited – used in protective clothing or wraps	Excellent – used in furnaces, pipelines
Acoustic Insulation	Moderate	Excellent for sound absorption
Fire Protection	Used in fire curtains, fire blankets	Used in fireproof insulation panels
Construction	As reinforcement in concrete or plaster	As an insulation layer in walls, roofs
Shipbuilding & Rail	As reinforcement and fire barriers	As thermal/sound insulation

4. Cost and Availability

Factor	Basalt Fiber Fabric	Basalt Fiber Needle Mat
Cost	Higher (due to weaving)	Lower (simpler production)
Form Factors	Rolls of various weaves	Sheets or rolls in multiple thicknesses

Summary: When to Use Which?

Use Case	Recommended Material
High-strength composite or laminate	Basalt Fiber Fabric
Thermal or sound insulation	Basalt Fiber Needle Mat
Fire-resistant blankets or curtains	Basalt Fabric (woven for flexibility)
Bulk insulation for industrial furnaces	Basalt Needle Mat
