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 preparation side of PPS composite
Method.
Background technology
Day by day flourishing due to industry and technology, and people are to the attention of energy saving standard, people it is also proposed to material that quality is light, intensity is high, modulus is high, be easy to the requirements such as manufacture, recoverable.Traditional homogenous material cannot meet such requirement.And the composite of the combinations of substances of two or more physics and chemistry different in kind can not only be met these requirements, also there is the designability of material, make the performance playing material to greatest extent become possibility.Therefore, the fields such as aerospace industries, auto manufacturing, shipping industry, high-grade sports equipment are studied, developed and be applied to composite in recent decades always energetically.
In existing market composite preparation process in, adopt to differ greatly, the shortcoming of existence is more, and due to by the restriction of process conditions, the stretch-proof performance of products obtained therefrom is not good, and the composite made realizes slower in engineering.
Summary of the invention
The technical problem that the present invention mainly solves is: the preparation method providing the PPS composite that a kind of combination property is good, tensile strength is high.
In order to solve the problem, technical scheme of the present invention is: a kind of preparation method of PPS composite, the steps include:
1) by PPS powder, by 15-20Kg/m
2inject mould, sprawl evenly, add fiber cloth, then above fiber cloth, PPS powder is pressed 25-30Kg/m
2inject mould, sprawl evenly;
2) mould that step 1) lays is put into hot press, the initial pressure of 1.6 ~ 1.8MPa, makes raw material more closely knit, with the speed of 10 ~ 12 DEG C/min, is heated to 285 ± 2 DEG C from room temperature in addition; And then with the speed of 4 ~ 5 DEG C/min, temperature rises to 318 ± 2 DEG C by 285 ± 2 DEG C of heating; Pressure is added to 3.5 ~ 4MPa, and keep temperature 318 ± 2 DEG C, pressure 3.5 ~ 4MPa, the time is 30 ~ 40min; The speed of l ~ 2 DEG C/min is down to room temperature, keeps pressure 3.5 ± 0.2MPa in temperature-fall period, is down to die sinking after room temperature, takes out PPS composite.
Described fiber cloth is glass fabric or carbon cloth.
Uniform method sprawled by the powder of PPS described in step 1): shake under adopting 200 ~ 500Hz
15~25s。
The invention has the beneficial effects as follows: this production technology is simple, and energy consumption is low, with short production cycle, products obtained therefrom
High, the applied range of hot strength.
