Problems solved by technology

[0003] In the traditional production process of biomass-based composite materials, the biomass fiber materials used are long, easy to entangle and absorb water during transportation, which directly leads to processing difficulties and poor apparent quality of products
Therefore, biomass fiber powder is often used as filler, and thermoplastic resin is used as adhesive to knead and extrude to produce homogeneous biomass-based composite materials. However, the plant fiber itself in this type of material is relatively fine, and it is further processed in the kneading process. Thinning, particularly low aspect ratio, loses the reinforcing effect of biomass fibers, and the final composite product is hard and brittle, low in strength, poor in toughness, and its application range is limited

Abstract

The invention discloses a forming device of a layered biomass composite material. The forming device comprises an upper layer discharge module, a lower layer discharge module, a fiber laying module and a pressing module. By means of the forming device, a biomass fiber material can be wrapped in thermoplastic resin sheets on the upper layer and the lower layer, and then the layered composite material can be obtained after pressing. The forming device is reasonable in design, biomass fiber does not need to be refined, and continuous production can be achieved; and the manufactured layered composite material is uniform in texture, smooth in surface and good in mechanical property.

Description

technical field [0001] The invention relates to the field of composite material forming devices, and more specifically, relates to a layered biomass composite material forming device. Background technique [0002] The development of high-filling biomass-based composite materials has a history of decades. With the continuous expansion of its application scope and the improvement of product structure requirements, the market's requirements for the surface texture of biomass fiber filling in biomass-based composite materials New requirements were put forward. [0003] In the traditional production process of biomass-based composite materials, the biomass fiber materials used are long, easy to entangle and absorb water during transportation, which directly leads to processing difficulties and poor apparent quality of products. Therefore, biomass fiber powder is often used as filler, and thermoplastic resin is used as adhesive to knead and extrude to produce homogeneous biomass-...
