Textured yarn continuous fiber reinforced plastic grain and producing method thereof

Abstract

The invention discloses a textured yarn continuous fiber reinforced plastic grain and a producing method thereof. According to the invention, the grain comprises a grain matrix and a textured yarn reinforced continuous fiber, wherein the textured yarn reinforced continuous fiber comprises two parts, i.e., core yarn and layer yarn; the core yarn is parallel to the axis of the grain matrix and uniformly distributed within the grain matrix; the layer yarn is loosely distributed around the core yarn; and according to the invention, the method mainly comprises the following three processes that: the process a for mainly finishing extrusion of the plastic matrix; the process b for mainly finishing the dispersion of the textured yarn and the molding of a grain strip; and the process c for mainly finishing the cooling, drying, granulating, collecting and the like of the grain strip. The textured yarn continuous fiber reinforced plastic grain and the producing method thereof, disclosed by the invention, have the following advantage that: because of double reinforcing of the core yarn and the layer yarn, the singleness of the reinforcing direction and various performances including machining performance are largely improved. The invention provides an effectively producing method of the plastic grain.

Description

technical field [0001] The invention relates to a fiber-reinforced plastic pellet and a production method thereof, in particular to a textured yarn long fiber-reinforced plastic pellet and a production method thereof. Background technique [0002] At present, in the long-fiber reinforced plastic pellets, the reinforcing fiber filaments are equivalent to the pellets, and they are distributed in parallel in the pellets. Therefore, the strength performance of the products is better, but due to the production process and other reasons, the filaments in the pellets are often It cannot be effectively dispersed and evenly infiltrated, so its processing performance is often not ideal. Therefore, although long fiber-reinforced plastic pellets have been widely used, there is still no fiber-reinforced plastic pellet and corresponding production method that can effectively improve injection molding performance and can effectively improve its reinforcement with a single directionality. ...

[0002] At present, in the long-fiber reinforced plastic pellets, the reinforcing fiber filaments are equivalent to the pellets, and they are distributed in parallel in the pellets. Therefore, the strength performance of the products is better, but due to the production process and other reasons, the filaments in the pellets are often It cannot be effectively dispersed and evenly infiltrated, so its processing performance is often not ideal

Therefore, although long fiber-reinforced plastic pellets have been widely used, there is no fiber-reinforced plastic pellet and corresponding production method that can effectively improve injection molding performance and can effectively improve its reinforcement with a single directionality.
