What the present invention provided prepares the method that described carbon fibers/fiberglass fabric is combined headpiece case, comprises the steps:
1), after described carbon fiber and glass fibre being cut into, according to proportioning, the size mated with the helmet, it is placed in preforming mould
Have I surface, and by flattening fixing shaping under the air draught suction function of mould air draught through hole generation, obtain preform；
2) in the mould II with glue-feeder, releasing agent is rubbed, by step 1) gained preform is transferred to institute
Stating in mould II, evacuation is also maintained at vacuum state, preheats described mould II simultaneously；
3) described flame-retarded resin is injected in described mould II with glue-feeder described in firming agent mixing tailing edge, inject
During keep described step 2) in vacuum state constant, after injecting glue, mould II is solidified, cold
But it is combined headpiece case to obtaining described carbon fibers/fiberglass fabric after the room temperature demoulding.
The step 2 of said method) in vacuum step, vacuum is-0.08 to-0.1MPa, specially 0.1MPa；
Described step 3) in, firming agent one in amine curing agent and methyl ethyl ketone peroxide；Wherein, described
At least one in diethyl amino propylamine, diethylamine, diamino-cyclohexane and m-xylene diamine of amine curing agent；
Described flame-retarded resin is 100:(50-2 with the mass ratio of firming agent), specially 100:20,100:2 or 100:
3。
In injecting glue step, need to strictly keep can not adulterating in vacuum and glue bubble；
In curing schedule, temperature is 80 DEG C-100 DEG C, and hardening time is 2h-3h.
The carbon fibers/fiberglass fabric composite flame-proof helmet that the present invention provides, due to double-deck in double-layer interlayer structure
Bottom surface all uses carbon fiber pilotaxitic texture, and interlayer uses erects glass fibre, and carbon fiber and glass fibre are by knot simultaneously
Node is embedding knits crosslinking, it is ensured that headpiece case is in the intensity of all directions and rigidity.Compared with existing fire hat housing,
Alleviate the weight of headpiece case by a relatively large margin.Simultaneously because have employed reinforcing fiber materials solid sandwich, play
Go out the advantage of structural mechanics design, it is possible to well resist the external impacts being perpendicular to the helmet, and have higher resistance to
Puncture resistance, lateral rigidity, electrical insulating property.
