Problems solved by technology

[0003] Although it has many advantages in mechanical properties, in some special fields such as high temperature, high humidity, high magnetic field and other environments, long-term exposure to this environment will cause the matrix to age, and the overall mechanical properties of the composite material will also decline, which also limits its performance. application, so the development of multifunctional continuous fiber reinforced thermoplastic composites has become a top priority

Abstract

Belonging to the technical field of high polymer materials, the invention relates to a thermoplastic resin prepreg tape and preparation method thereof. The thermoplastic resin prepreg tape comprises the following components by weight: 30-80% of thermoplastic resin; 10-60% of a fiber; 0.5-3% of a compatilizer; 0.2-0.5% of an antioxidant; 0.3-2% of a lubricant; and 1-40% of a wave-absorbing material. In the invention, mainly the wave-absorbing material is added to the prepreg tape so as to make the continuous fiber reinforced thermoplastic resin prepreg tape have a wave-absorbing property. The continuous fiber reinforced thermoplastic resin prepreg tape has high strength and a wave-absorbing property at the same time, and can be applied to anechoic chambers, microwave communication, electronic equipment, medical equipment and other fields, thus enhancing product competitiveness and expanding application scope.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a thermoplastic resin prepreg tape and a preparation method thereof. Background technique [0002] Continuous fiber reinforced thermoplastic resin composites exhibit high mechanical properties due to the continuous distribution of fibers in the matrix. At the same time, because of its fast forming speed and recyclable use, it has become the focus of attention. The zeniconTM product developed by Crane Composite Materials Company of the United States uses hot-melt resin to form continuous fibers in the 0° / 90° axial direction, and then consolidates them into plates of required thickness with multiple layers. The panels are available in several thermoplastics (polypropylene, polyethylene, PET, nylon) and in several reinforcing fibers (glass fibres, carbon fibres, aramid fibres). According to strength requirements, the fiber content can be 40% to 80%. Chinese patent CN 1294...
