Abstract
The invention discloses a preparation method of a PPS (polyphenylene sulfide) composite material, which comprises the following steps: 1) uniformly spreading PPS powder and fiber cloth alternatively; and 2) placing a mold, in which the PPS powder and the fiber cloth are spread, in the step 1) into a hot press, pressurizing and heating according to steps and then cooling and finalizing to open the mold to obtain the PPS composite material. The production process is simple and has low energy consumption and a short production cycle. The obtained product has high tensile strength and a wide application range.
Description
Technical field
The present invention relates to technical field of composite materials, be specifically related to a kind of PPS composite manufacture side
Method.
Background technology
Because industry is day by day flourishing with technology, and people are to energy-conservation and attention environmental protection, and people have proposed also to material that quality is light, intensity is high, modulus is high, be easy to the requirements such as manufacturing, recoverable.Traditional homogenous material can't satisfy such requirement.And the composite that the combinations of substances of two or more physics and chemistry different in kind forms can not only be satisfied these requirements, and also have the designability of material, become possibility so that bring into play to greatest extent the performance of material.Therefore, composite is studied, is developed always and be applied to the fields such as space flight and aviation industry, auto manufacturing, shipping industry, high-grade sports equipment in recent decades energetically.
In the composite manufacture process, adopt in order to differ greatly in the existing market, the shortcoming of existence is more, owing to be subjected to the restriction of process conditions, the stretch-proof performance of products obtained therefrom is not good, and the composite that makes is realized slower in engineering.
Summary of the invention
The technical problem that the present invention mainly solves is: the PPS composite manufacture that a kind of combination property is good, tensile strength is high method is provided.
In order to address the above problem, technical scheme of the present invention is: a kind of PPS composite manufacture method the steps include:
1) with the PPS powder, presses 15-20Kg/m
2Inject mould, sprawl evenly, add fiber cloth, then above fiber cloth, the PPS powder is pressed 25-30Kg/m
2Inject mould, sprawl evenly;
2) mould that step 1) is laid is put into hot press, and the initial pressure of 1.6 ~ 1.8MPa makes raw material more closely knit in addition, with the speed of 10 ~ 12 ℃/min, is heated to 285 ± 2 ℃ from room temperature; And then with the speed of 4 ~ 5 ℃/min, temperature rises to 318 ± 2 ℃ by 285 ± 2 ℃ of heating; Pressure is added to 3.5 ~ 4MPa, keep 318 ± 2 ℃ of temperature, pressure 3.5 ~ 4MPa, the time is 30 ~ 40min; The speed of l ~ 2 ℃/min is down to room temperature, keeps pressure 3.5 ± 0.2MPa in the temperature-fall period, is down to die sinking after the room temperature, takes out the PPS composite.
Described fiber cloth is glass fabric or carbon cloth.
The powder of PPS described in the step 1) is sprawled uniform method: adopt under 200 ~ 500Hz and shake
15~25s。
The invention has the beneficial effects as follows: this production technology is simple, and energy consumption is low, and is with short production cycle, products obtained therefrom
High, the applied range of hot strength.
