Product Description

PLEASE CONTACT US FOR DATA SHEET IF YOU NEED.

Glass fiber pultrusion: the main reinforcement materials used in pultrusion process are glass fiber and its products, such as untwisted roving, glass fiber felt, etc. In order to meet the special performance requirements of the products, we can use aramide fiber, carbon fiber, ultra-high molecular weight polyethylene fiber and basalt fiber.

(1) Glass fiber
The glass fibers used in pultrusion process are mainly alkali free, medium alkali and high strength glass fibers.
The varieties of glass fiber products are:

1.no twist roving
Untwisted roving has double and direct yarns with linear densities of 1100 (1200) to 4400 (4800). Requirements: good band forming; Good regression; Uniform tension; Uniform linear density; Good permeability.

2.glass fiber felt piece
Requirements for chopped felt: uniform area and quality; The distribution of shorted primordium and C binder was uniform. Moderate dry felt strength; Good permeability. Used for products with low strength requirements.
The reinforcing effect of continuous felt is better than that of chopped felt. Ditto the above requirements.
The surface felt provides surface modification and acid resistance.
Stitching felt does not contain binder, good permeability, low price.

3. glass fiber knitted fabric can increase the tensile strength and bending strength of the products; Reduce the weight of products; The surface of the product is smooth and smooth.

4. Combination of glass fiber reinforced material, can adjust the transverse and longitudinal strength of products.
