A kind of plastic template and production method of lft strip fabric reinforced core layer

Abstract

The invention discloses a plastic formwork of an LFT material strip fabric reinforcing core layer and a producing method of the plastic formwork. The plastic formwork comprises a plurality of layers of stacked fabric layers made of LFT material strips, and surfaces of the fabric layers and interlamination of the fabric layers are filled with and covered with thermoplastic plastics. According to the plastic formwork of the LFT material strip fabric reinforcing core layer and the producing method of the plastic formwork, the fabric layers made of the LFT material strips are used as the reinforcing core layer, the problem that GF fabric layers cannot be easily infiltrated and covered by the thermoplastic plastic melt bodies completely is solved, and the mechanical strength of the plastic formwork is improved.

Description

technical field [0001] The invention mainly relates to the field of glass fiber composite materials, and mainly relates to the production technology of glass fiber composite pellets. Background technique [0002] Thermoplastics have light weight, good acid and alkali corrosion resistance, and can be recycled and reused many times. The development speed is very fast. A development trend in the world. However, building formwork has high requirements on mechanical properties and dimensional stability, and requires certain heat resistance, and is easy to install and use. Therefore, fiber reinforced thermoplastics (RFTP) are usually used. Based on the size requirements of building formwork, it is difficult to use LFT or SFT reinforcement. Forming method, but using LFT or SFT compression molding, not only the process and other problems, but also it is difficult to ensure the uniform mechanical properties of the template. However, when GF (glass fiber) fabric and thermoplastic sh...

Problems solved by technology

However, building formwork has high requirements on mechanical properties and dimensional stability, and requires certain heat resistance, and is easy to install and use. Therefore, fiber reinforced thermoplastics (RFTP) are usually used. Based on the size requirements of building formwork, it is difficult to use LFT or SFT reinforcement. Molding method, but the use of LFT or SFT compression molding, not only the process and other problems, but also difficult to ensure uniform mechanical properties of the template

However, when GF (glass fiber) fabric and thermoplastic sheet are used for molding production, it is difficult to make the plastic melt soak into the GF fabric well, that is, the interface between the GF fabric and the plastic is prone to problems such as exposure, which makes it difficult to meet the requirements for mechanical properties of the product.
