Manufacturing method and product of carbon fiber grid cloth reinforced composite thermoplastic pp sheet

Abstract

The invention discloses a preparing method of a carbon-fiber-gridding-fabric-reinforced composite thermoplastic PP plate. The preparing method is characterized by including the following steps that materials are prepared, wherein carbon-fiber gridding fabric, PP non-woven fabric and a thermoplastic raw material comprising, by mass, 40-50 parts of copolymerization PP, 50-60 parts of common PP, 0.1-0.2 part of main antioxidant, 0.1-0.5 part of auxiliary antioxidant, 0.1 part of light stabilizer, 0.6 part of heat stabilizer, 1.2 parts of color master batches and 0.4 part of mineral oil are prepared; the materials in the formula are added into a mixing machine and fully mixed ready for use; the mixed materials are fed to a drying cabin to be dried ready for use; the dried materials are fed into containing hoppers of three plastic extruding machines respectively, the materials are automatically fed into the three plastic extruding machines through the containing hoppers, melted PP is extruded to form soft piece blanks through the three plastic extruding machines at the same time, and the carbon-fiber gridding fabric and the PP non-woven fabric pre-arranged on composite devices installed above and below the three plastic extruding machines are sequentially led into the portions between pressing rollers of three plastic extruding composite machines respectively to be soaked and laminated to form the composite plate.

Description

technical field [0001] The invention relates to a manufacturing method and product of a thermoplastic plate, in particular to a manufacturing method and product of a carbon fiber grid cloth reinforced composite thermoplastic PP plate. Background technique [0002] As we all know, in order to achieve lightweight of automobiles, the first thing is to reduce the weight of auto parts. The lightweight of auto parts involves the lightweight of raw materials. Researchers at home and abroad have done a lot of research on the lightweight of automotive materials: using polypropylene foam materials to make car interior decoration top covers, columns, door panels, etc.; using carbon fiber reinforced composite thermoplastic materials to make car shells, bottom guards, hoods, etc. Wait. The development direction of automotive materials is to replace solid materials with foamed materials. Replacing aluminum plates and steel plates with carbon fiber and glass fiber reinforced composite p...

Problems solved by technology

For example: Tianjin Polytechnic University adopts continuous impregnation of carbon fiber cloth. Because the carbon fiber cloth is densely woven, it is difficult for the thermoplastic resin to completely cover the carbon fiber during the impregnation process, which will lead to weak bonding between the carbon fiber cloth and PP and affect the performance of the material; Beijing Nashengtong The company's use of carbon fiber unidirectional arrangement composite prepreg tape will lead to the defect of inconsistent vertical and horizontal strength
