For achieving the above object, the present invention is by the following technical solutions:
A kind of high-strength thermoplastic composite plastic seat component, comprise the reinforced rib that parts are facial and support component is facial, the fiber in parts face comprises at least one deck continuous fiber, and the fiber in reinforced rib is long fibre.
Described continuous fiber is one deck.
Described continuous fiber is at least two-layer, between continuous fiber layer adjacent every or continuous fiber layer between sandwiched long fibre layer.
Described continuous fiber is thermoplastic resin impregnated continuous unidirectional fibre, the two-way fiber of intersection laying, or at least one in fabric.
Described parts are back of seat, seat sitting face or back of seat and the integrated chair top of seat sitting face.
The thermoplastic base resin that the thermoplastic base resin of described continuous fiber dipping and long fibre flood is same resin.
The thermoplastic base resin that the thermoplastic base resin of described continuous fiber dipping and long fibre flood is different resins.
The preparation method of high-strength thermoplastic composite plastic seat component, comprises the steps:
Step one, cuts out the thermoplastic resin impregnated continuous fiber sheet with seat component shape and weight-matched;
Step 2, cuts out the long fiber thermoplastic resin sheet with seat component shape and weight-matched;
Step 3, heats the continuous fiber sheet of step one, and is heated by the long fiber thermoplastic resin sheet of step 2, or the long fibre material mated with seat component is heated in preparation separately, and heating-up temperature is 200-240 DEG C;
Step 4, the continuous fiber thermoplastic resin sheet heat step 3 and long fiber thermoplastic resin sheet lamination are inserted in mould, or by the continuous fiber thermoplastic resin sheet heated described in step 3 and long fibre material is stacked inserts in mould, the wherein cavity body of mould in the corresponding seat part side portion of continuous fiber thermoplastic resin sheet, long fibre sheet or long fibre material corresponding be reinforced rib cavity body of mould;
Step 5, compression molding, die pressure 1500-1800T/M
2, patrix temperature 30-80 DEG C, counterdie temperature 30-80 DEG C, dwell time 40-90s.
Preparation process of the present invention is simple, production efficiency is high.By dipping and die press technology for forming, make seat component have higher strength-to-density ratio and specific modulus, product has the feature such as designability, lower density; Layout and the orientation of two kinds of fibers complement each other, and use long fibre in reinforced rib, avoid the phenomenon that in compressing process, fiber easily ruptures, and substantially increase the strength-to-density ratio of product, specific modulus and impact resistance.The present invention has compared with traditional production technology that energy consumption is little, production efficiency is high, and cost is lower, and the dimensional accuracy of product have also been obtained raising.
