In the method for manufacturing equipment part, in particular for manufacture seat insert element, handrail or headrest pad member
The aspect of the method for part, according to the present invention, the task is solved in the following manner：It regard fiber and bonding agent as fiber composite material
Material is placed in mould, wherein, fiber is connected by bonding agent and drip molding is shaped to, the drip molding is (outstanding by local compacting
Its hot extrusion or cold extrusion), wherein, by least one formed body, especially functional 3D formed bodies, such as parts, component
Or functional part, such as injection moulding is on the drip molding in the region being compacted of the drip molding.
Especially using heat-curable adhesive or preferably used based on natural rubber or synthetic rubber, especially as bonding agent
It is the bonding agent based on chlorobutadiene.By using heat-curable adhesive or the bonding agent based on rubber (bonding agent is in room
It is solid-state under temperature, but at least deformable in the time interval of 30 minutes, 8 hours, 12 hours or 48 hours) and pass through
Local compacting compactly extrudes the thermoplastic composition in the drip molding, and the bonding agent is made as a compact and shaping
Seal equally works.Especially at room temperature at least in the time range from 20 seconds to 180 seconds with area and/
Or pressure is molded the drip molding relevantly.For example at room temperature up to 20,40,60,80,100,120,140,160 or
180 seconds ground part it is relevant with pressure be molded the drip molding.
(also referred to as vitrifying turns the glass transition temperature of bonding agent based on rubber, especially natural rubber or synthetic rubber
Temperature or referred to as Tg) it is about 50 DEG C.If provided, with the drip molding based on natural rubber or the bonding agent of synthetic rubber by fibre
Dimension composite is molded in the case of such as 50 DEG C, especially pressure forming, then polymer chain has certain motility simultaneously
And can --- using in the case of high briquetting pressure --- along sliding over each other.This is based on：Such as 50 DEG C or 60 DEG C of shaping
Temperature is in the range of significantly higher than glass transition temperature but less than softening range.Especially make the drip molding in room temperature
Local pressure is molded for example within the temperature range of from 30 DEG C to 100 DEG C above.
Bonding agent, especially its polymer invaded in fibrous composite can be in the case of unbroken with certain
Degree flows, wherein, the drip molding, the especially drip molding kept together by bonding agent each fiber (=it is by invading
The matrix that the bonding agent entered is constituted with fibrous composite) deformed, especially by pressure forming.
In the case of pressure forming, for example, apply squeeze pressure in die casting, the squeeze pressure has from 10
Ton is to adjustable extruding force in the range of 1000 tons.The extruding force depends on forming temperature and area to be formed herein.
