Light carbon fiber case integral forming manufacturing method

Abstract

The invention discloses a light carbon fiber case integral forming manufacturing method. The light carbon fiber case integral forming manufacturing method comprises the following contents of pre-formation of guide rails and wedge-shaped parts; implementation of threaded installation holes, wherein the threaded installation holes are implemented through metal embedded parts, bottom installation holes are pre-machined in the metal embedded parts, and the metal embedded parts are precisely positioned on the forming surface of a case die through the pre-machined bottom installation holes; pre-formation of side face installation beams; case body lay-up; machining; surface metallization on the inner surface and the outer surface of the case body; and surface three-proofing treatment. According to the light carbon fiber case integral forming manufacturing method, reasonable split design is carried out, the guide rails, the wedge-shaped parts and side face connecting beams are pre-formed and then assembled with the case body die, overall case body lay-up and autoclave co-curing formation are carried out, the manufacturing difficulty is lowered, and the overall rigidity requirement of the case body is also ensured; many printed board assemblies need to be installed in the case body, a power supply component needs to be installed outside the case body, installation interfaces are many, the positions are compact, the high-precision requirement for installation positions and dimensions is met through the embedded part precise positioning technology, and the connecting strength is ensured.

Description

technical field [0001] The invention relates to a manufacturing method for integral molding of a chassis, in particular to a manufacturing method for integral molding of a lightweight carbon fiber chassis. Background technique [0002] The publication number is CN 105856756A, which discloses a carbon fiber composite box and its preparation method.
