I: Preparation of thermoplastic composite sheets

refer to image 3 , the thermoplastic composite sheet to be prepared presents an up-down symmetrical structure and consists of the following layers:

The first layer (upper surface layer) is PC film with a size of 650mm×750mm;

The second layer (intermediate layer) is a 0 degree carbon fiber reinforced polycarbonate unidirectional tape with four first localized reinforcement areas by cutting out the 0 degree carbon fiber reinforced polycarbonate unidirectional tape in the four areas The tape is then formed by replacing the excised area with a PC film, the size of the first local enhancement area is 90mm × 78mm, the distance to the side in the 0-degree direction approaching is 32.5mm, and the distance to the side in the 90-degree direction approaching is 30mm;

The third layer (middle layer) is a 90 degree carbon fiber reinforced polycarbonate unidirectional tape;

The fourth layer (middle layer) is the same as the third lay...

Abstract

The invention relates to a thermoplastic composite board as well as a processing method and a product thereof. The thermoplastic composite board comprises an upper surface layer (11), a lower surface layer (13) and one or more middle layers (12), wherein the upper surface layer (11) and the lower surface layer (13) are laminated together; the middle layers (12) are arranged between the upper surface layer (11) and the lower surface layer (13); the upper surface is composed of the upper surface layer (11), the lower surface is composed of the lower surface layer (13), and the first side face (14), the second side face (15), the third side face (16) and the fourth side face (17) are sequentially adjacent to one another. The thermoplastic composite sheet (1) has at least one first local reinforcement region (18-21) close to the intersection of adjacent sides and at least one second local reinforcement region (22-23) close to any one of the sides (14-17). The thermoplastic composite board provided by the invention has a local reinforcing area, and a product prepared from the thermoplastic composite board is locally reinforced, so that the local impact resistance and / or static loading capacity are / is improved, and a better balance among strength, rigidity and light weight of a final product can be realized under the condition that the overall structural weight is not obviously increased.

Description

technical field [0001] The present invention relates to the technical field of composite material manufacturing. Specifically, the present invention relates to a thermoplastic composite sheet and its preparation method and products. Background technique [0002] Luggage (also known as travel case), including trolley cases, is a box that is carried when going out to store items. The use of luggage is more and more common because the luggage is bulky, can be pulled and can greatly reduce the drag force of the user. [0003] Early suitcases were made of wood or other heavy materials. With the popularity of air travel, luggage materials tended to be lighter, hard plastic or cloth. In the current luggage material market, composite materials are one of the optional materials for manufacturing high-strength and high-hardness luggage, but at the same time, high strength and high hardness often mean that the luggage is relatively heavy. [0004] In the traditional manufacturing pr...
