Description
Technical field
The present invention relates to Fibre Optical Sensor paving field, particularly to a kind of automatic paving in carbon fiber prepreg surface optical fiber
The apparatus and method of sensor.
Background technology
Optical fiber is the filament pulled into by quartz, a diameter of 15 μm～50 μm, thus and fragile and frangibility, so most
Optical fiber before use must be by which floor protection structure cladding, and the cable after cladding is i.e. referred to as optical cable.Owing to optical fiber can be experienced
Ambient temperature and the change of strain, therefore use optical cable carry out thermometric or survey strain in a lot of occasions.
Carbon fiber prepreg has certain viscosity, and viscosity refers to the ability that self pastes mutually at a certain temperature, with
A piece of prepreg, the low viscosity that may lose of temperature, temperature height toughness again, temperature difference about 5 DEG C, viscosity just has substantially change
Change.Losing, for viscosity, the prepreg that the time do not grows, slightly improve temperature, viscosity is improved, and can realize the paving work of parts
Skill, test shows not have much affect its mechanical property.Viscosity should not be the biggest, in order to can separate again when laying is wrong
Carry out paving and prepreg is unlikely to damaged；Viscosity can not be the least, so that two pieces of prepreg energy at the working temperature
It is pasted together and is unlikely to separately.
