Problems solved by technology

[0003] At present, most of the reinforced notebooks in the world are made of aluminum alloy. Although they can protect the notebook computer to a certain extent, they cannot be directly cushioned by the aluminum alloy material. Additional rubber parts must be added to achieve this. The cushioning effect makes its reinforced shell too bulky and heavy, which greatly reduces its portability

preparation example Construction

[0036] The invention provides a method for preparing a carbon fiber composite material for reinforcing a notebook computer casing, comprising the following steps:

[0037]The notebook computer shell mold is divided into a hardening zone and a buffer zone, the hardening zone is the central part of the notebook computer shell mold, the buffer zone is the peripheral edge part of the notebook computer shell mold, the hardening zone and the buffer Die isolation boards are set between zones;

[0038] The carbon fiber cloth is laid flat in the notebook computer casing mold to obtain a mold for laying the carbon fiber cloth;

[0039] Mixing bisphenol A type diglycidyl ether prepolymer and amine curing agent, pouring in the hardening area, and then pre-curing to obtain the pre-curing hardening area;

[0040] After removing the mold isolation plate, apply a silane coupling agent at the interface between the hardening zone and the buffer zone;

[0041] Mix isocyanate and hydroxyl-termi...

Embodiment 1

[0066] Fiber laying: Cut T700 plain weave carbon fiber cloth according to the size of the mold (T700 carbon fiber cloth, the surface density is 198g / m 2 , with a thickness of 0.23mm), and lay 15 layers in the mold;

[0067] Casting in the hardening area: fully mix the bisphenol A diglycidyl ether prepolymer and the curing agent diethyltoluenediamine, the mixing mass ratio is 78 parts of T700 carbon fiber cloth, 18 parts of bisphenol A diglycidyl ether, two 6 parts of ethyltoluenediamine, poured in the hardening area, heated to 90°C, and continued for 60 minutes for pre-curing;

Abstract

The invention provides a carbon fiber composite material for reinforcing a notebook computer shell and a preparation method of the carbon fiber composite material, and belongs to the technical field of composite materials. According to the invention, the bisphenol A type thermosetting epoxy resin is combined with the carbon fiber cloth, so that the carbon fiber cloth has good mechanical propertiesand processing formability, and can play a good role in protecting the whole notebook computer; the polyurethane elastomer has the advantages of being resistant to abrasion, cutting and tearing, highin bearing capacity, transparent or semitransparent, resistant to ozone, pourable, pourable and wide in hardness range, the polyurethane elastomer is combined with the carbon fiber cloth to serve asa buffer area of the shell, a large amount of impact energy can be absorbed, and a good buffer effect on mechanical impact is achieved. According to the preparation method, a partition ternary integrated polymerization method is adopted, bisphenol A thermosetting epoxy resin and a polyurethane elastomer are crosslinked and combined into a whole in the heat treatment process through a silane coupling agent, and it is guaranteed that different components can exert the maximum effect in corresponding protection areas.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a carbon fiber composite material used to reinforce a notebook computer casing and a preparation method thereof. Background technique [0002] In today's highly informationized society, electronic computers have become an indispensable and important tool in people's daily production and life. With its portability and mobility, notebook computers are widely used in various non-fixed usage scenarios. Ordinary notebook computer shells are generally made of plastic or aluminum alloy. Although the portability is guaranteed, the protection performance of the notebook is not good enough, and it cannot withstand severe impacts and vibrations. However, in some special application fields or relatively harsh use environments, in order to protect important precision components inside the computer and prevent damage to the core hardware of the notebook computer during shocks and ...
