Embodiment

[0054] The present invention will now be described with reference to the following examples, which should be considered illustrative rather than restrictive in every respect.

[0055] Treatment of glass fiber with hydrophilic surface coating

[0056] 1. Cut E-glass fibers to an average fiber length of 3400 microns, and then grind to an average length of 700 microns.

[0057] 2. Use boiling water and strong detergent to clean the ground glass fiber under strong stirring. Then rinse the detergent from the fiber.

[0058] 3. Suspend 1% w / w methacryloxytrimethoxysilane (Dow Z-6030) in pH 4 water, and add the fibers to the suspension. The resulting mixture was vigorously stirred at room temperature for 60 minutes.

[0059] 4. The liquid then flows off the glass fibers, leaving them still wetted by the mixture.

[0060] 5. The Z-6030-treated fiber is then dispersed again in water with a pH of 7.

[0061] 6. Separately, in the presence of a tin catalyst (such as tributyltin), the solution of Z...

Abstract

The present invention relates to a reinforced composite material and a method for its production. The composite material comprises at least one cured resin having a reinforcing material. Preferably the reinforcing material is a plurality of glass fibres which are treated such that the properties of the interphase substantially surrounding each fibre are substantially equivalent to those of the bulk cured resin. The fibre treatment may be selected from the group consisting of a polymeric coating, a hydrophilic surface coating, a surface coating of a free radical inhibitor, or a reduction in the total surface area of the fibres. The reinforced composite material of the invention provides improved long-term mechanical properties compared to traditional glass fibre reinforced materials.

Description

technical field [0001] The present invention relates to reinforced composites, and in particular, to fiber reinforced polymer composites. However, it should be understood that the present invention is not limited to this specific field of application. Background technique [0002] Any discussion of prior art throughout this specification should in no way be considered an admission that such prior art is widely known, or forms part of the common general knowledge in the field. [0003] Fiber reinforced polymer composites are known in the art and are generally prepared by reacting a curable resin with a reactive diluent in the presence of a free radical initiator. Typically, the curable resin is an unsaturated polyester resin, and the reactive diluent is a vinyl monomer. Reinforcing materials such as glass fibers are often included in the formulation to provide dimensional stability and toughness. This reinforced composite is used in many critical industrial applications, i...
