1. Fiberglass Fabric & Glass Fiber: Overview

Fiberglass fabric is a woven textile made from continuous glass filaments. Glass fiber is available in two primary grades: E-glass (electrical grade, most common) and S-glass (structural grade, higher strength). At Impact Materials, we supply both E-glass and S-glass products to meet diverse performance and budget requirements.

Key Properties:

  • Tensile Strength: 3,445 MPa (E-glass), 4,800 MPa (S-glass)
  • Density: 2.58 g/cm³ (E-glass), 2.49 g/cm³ (S-glass)
  • Electrical Insulation: Excellent
  • Chemical Resistance: Superior
  • Cost: Most economical composite reinforcement

4. FAQ

Q: What is the difference between E-glass and S-glass?

A: E-glass is the standard electrical grade with good all-around properties. S-glass offers 40% higher tensile strength and is used for structural aerospace applications.

Q: What resin works best with fiberglass?

A: Polyester resin is most common for general use. Epoxy resin offers superior mechanical properties. Vinyl ester provides best chemical resistance.

Q: Do you offer free samples?

A: Yes! Impact Materials provides free A4-sized samples (210×297mm) for evaluation. Standard samples ship within 3-5 days via express courier.
