Description

Aramid fiber-glass fiber composite sheet and its preparation method

technical field

The invention belongs to the technical field of fiber composite materials, and in particular relates to an aramid fiber-glass fiber composite sheet and a preparation method thereof.

Background technique

Glass felt is a base material without any binder or other stitching materials. Continuous glass fibers with a certain linear density are randomly distributed in a circle to form a substrate with a certain thickness. Products that are joined together. It has good compatibility with different matrix resins, and is suitable for various molding processes such as molding and compression, and is applied to reinforced modified polypropylene, epoxy and unsaturated polyester resins. However, the strength and flexibility of the glass mat need to be improved, and there are many hairs on the surface, which limits its application in some scenarios.

The full name of aramid fiber is aromatic polyamide fiber, which is an organic synthetic fiber with high strength, high modulus, low density and high wear resistance. In the early 1960s, aramid fiber was developed by DuPont of the United States as a meta-polyaramid fiber with excellent performance. The product name is NOMEX, and it is called 1313 fiber in my country; Kevlar, our country calls it 1414 fiber.

Therefore, in view of the defects of glass mat, there are currently researches and related products on the modification of glass mat by using aramid fibers. For example, a highly flame-retardant aramid fiber laminate containing aromatic heterocycles has appeared on the market. It is made of heterocyclic aramid filaments arranged together and composited with thermoplastic resins to form a sheet. Because the directionality of the fibers makes The properties of this sheet are anisotropic. There is also a glass fiber and aramid fiber composite cloth on the market, which is made by weaving glass fiber and aramid fiber through warp and weft, which overcomes the problem that glass fiber reinforced plastic products have only rigidity but no flexibility and are not impact resistant.

Through the analysis of the above-mentioned existing composite materials, it is found that the existing related composite materials are generally made of aramid fiber into aramid paper or aramid cloth, and then compounded with other materials, heated and pressurized. It is complex and requires high equipment, resulting in high production costs. In addition, due to the complexity of the process, the performance stability of the produced composite material is poor, and the qualified rate is relatively low.

Due to the own characteristics of the glass mat, the aramid fiber, aramid fiber The pulp will penetrate the glass mat, so that the aramid fiber, aramid pulp, and glass fiber are bonded and penetrated each other, so that the composite aramid layer and the glass mat matrix are firmly bonded, effectively avoiding the phenomenon of peeling and separation of the two, and at the same time giving the aramid Excellent mechanical properties such as tensile strength and bending strength of the fiberglass composite sheet. In addition, the composite aramid fiber layer is combined on the surface of the glass mat substrate, so that the surface of the aramid fiber-glass fiber composite sheet is relatively smooth, which overcomes the defect that there are many hairs distributed on the surface of the glass mat.

In the preparation method of the aramid fiber-glass fiber composite sheet described above, the mixed slurry of aramid fiber and aramid pulp is coated on the surface of the glass mat, and the characteristics of the glass fiber mat having many voids are utilized, as the aramid fiber and the pulp are evenly distributed.
