The additional aspect and advantage of the present invention will be set forth in part in the description, and partly will become from the following description
Obtain substantially, or recognized by the practice of the present invention.
Specific embodiment
Embodiments of the invention are described below in detail, the embodiment is exemplary, it is intended to for explaining the present invention, and
It is not considered as limiting the invention.
As described in the background art, PEI+30% glass fibre is due to density is low, high temperature resistant, excellent electrical insulating property
Etc. characteristic, it is chosen to be applied in the specialities such as the aviation helmet of pilot.It is less to there is thickness in this kind of specialities,
The characteristics of generally no greater than 2mm, applicant in actual use, find the material made by housing become at different temperatures
Shape is larger, affects the performance of product.
In order to improve accessory size stability at different temperatures, it is ensured that product quality, determine by heat treatment method
Part stress is eliminated, makes accessory size change minimum under condition of different temperatures.At present, prior art does not disclose PEI+
The heat-treatment technology method of 30% glass fiber compound material thin-walled workpiece.
Applicant passes through lot of experiments and theory analysis, it is found that the digital control processing with PEI+30% glass fibre as substrate is thin
After wall pieces are machined, which is adopted 160～190 DEG C are warming up in couveuse, be then incubated 1h-4h, subsequent natural cooling
To the ageing hot processing method of room temperature, thin-wall part stress after processing can be discharged.Meanwhile, further quantization assessment housing is not
It is synthermal with the time under timeliness, find a kind of best heat-treatment protocol of stress-removal effect, meet material making aboard
With requiring.
The part of machine-shaping is divided into 16 batches, different time is carried out with different temperatures to the part of different batches
The high/low-temperature impact of annealing and different temperatures and time, specific processing step is：
1. the digital control processing thin-wall part pair with PEI+30% glass fibre as substrate is processed, and makes sample.And to examination
Sample housing is numbered.
2. timeliness scheme is divided into 4 groups, respectively 160 DEG C, 170 DEG C, 180 DEG C, 190 DEG C.4 are divided into according to temperature retention time
Group, temperature retention time are respectively 1h, 2h, 3h, 4h.16 heat-treatment protocols are given birth to according to different temperature and temperature retention time common property.
The heat treatment method process control parameter of 1 16 heat-treatment protocols of table
