For strong composite laminates in fibreglass projects, it’s critical to use the right resins and reinforcements. Polyester, vinyl ester, and epoxy resins are coupled with fibreglass cloth, mat, and carbon fibre as reinforcements. 

For components like drive belts, clutch discs, brake pads, headliners, and insulation, automotive applications benefit from fibreglass yarns, impregnated glass cords, treated glass cords, and woven fibreglass, which provide tensile strength, temperature resistance, and dimensional stability.

BLG Fiberglass Manufacturing is an automotive fiberglass supplier in USA and other countries worldwide. Their factory can produce parts for a wide range of automotive vehicles, including medium trucks, heavy trucks, recreation vehicles, mass transit, and speciality vehicles. Their products are made to enhance the vehicle’s appearance and performance. 

Types of Fibreglass Reinforcement and Their Needs 

Fiberglass Cloth: 

A lightweight and durable material suitable for composite parts, molds, and repairs when combined with resin. Lighter-weight fabrics treated with resin are preferred for waterproofing.

Chopped Strand Mat: 

Consists of short fibres randomly adjusted and held by a resin binder, offering flexibility to mould according to curves and tight spaces in polyester and vinyl ester resins.

Carbon Fiber: 

Renowned for strength, lightweight, and aesthetics, used in the automotive, sports, and aerospace industries. A yard of carbon fibre fabric contains millions of tiny filaments that distribute weight when woven together, forming a robust fabric.

Knitted Fabric: 

Stitched knitted fabric ensures rapid wetting, directional strength, and time savings in multi-layer layups. Compatible with polyester, vinyl ester, and epoxy resin, even when combined with mat.

Types of Resins 


Epoxy is renowned for its strong strength, superior adhesion, and adaptability across a variety of applications.


Polyester is affordable, simple to use, and appropriate for projects with a variety of uses.

Vinyl Ester: 

In comparison to polyester, vinyl ester offers better durability and chemical resistance.


For a variety of uses, polyurethane offers flexibility, abrasion resistance, and impact strength.


Perfect for applications requiring high-temperature resistance and fire-resistant qualities.


In certain applications, silicone is renowned for its superior heat resistance, electrical insulation, and weather ability.


For outdoor and visual applications, acrylic offers UV protection, clarity, and chemical resistance.

During the moulding process, fibre selection must be carefully considered. Other materials are also competing for customers’ attention in the market.
