Product properties / advantages:

BFCE can be used in the following production technologies:

Filament Winding
Pultrusion
Knitting and Weaving (less texturized option)
Long Fiber Technologies (LFT)

The BFCE, are giving the following advantages and benefits in comparison to the non-texturized glass fiber roving:

Better and faster resin wetting properties
Greater fiber volume, which minimize the risk of “holes” voids in final composite product
Possibility to use resins with higher density and additional resin fillers
Keeps high volume during processes requiring high pulling/winding tension

The Core-Effect type of texturizing makes the BFCE resistant to the volume reduction of the fibers when being pulled during the resin application and forming.

The Core-Effect Bulky Fibers (BFCE) are produced in Air-Jet Technology. This technology allows to use a standard Glass Fiber Direct Roving as a base material, which can be transformed into the highly volumized product.

Core-Effect Bulky Fibers (BFCE) are the most efficient alternative on the market, which provides a constant bulky fiber volume in low and high pulling tension.

Figure 3 – The comparison of Standard (BFR) Bulky Roving with (BFCE) Core-Effect Bulky Fiber

The fibers presented on the Picture above (Figure 3), are showing the major differences in the material structure. The Core-Effect Bulky Fiber (BFCE) has most of the monofilament fibers separated from each other. The separated fibers are oriented in „wave form pattern“. The wave amplitude is much greater than Standard Bulky Fiber (BFR) and can be „adjusted“ in the air-jet texturizing process, according to the preferences of final customer.

The biggest advantage for BFCE, is that it is able to keep the high volume, even after putting a high tension on the fiber.

Please see the comparison pictures of standard texturized direct roving and Core-Effect roving under low and high tension:

Figure 4 - Glass fiber volume comparison of BFR with BFCE under high tension

The BFCE keeps the same volume under high pulling/winding tension in comparison to Standard BFR glass fiber (Figure 4).

The advantages of (BFCE) in comparison to standard (BFR):

The „wave-form“ amplitude of the(BFCE) is much higher than the (BFR).
The „wave-form“ pattern and material volume of (BFCE) does not reduce under high tension.
Possibility to MIX the fibers with in the end product (Possible to mix higher grade materials like S-glass on CORE and E-glass or ECR on EFFECT.

NBTA’s texturizing process enables to MIX the fibers to create the “Tailor Made product”.

It is possible to MIX the E-glass with ECR-glass and S-glass fibers to add additional tension strength to the final NBTA’s products as BFR and BFCE
