JPS60204308A - Manufacture of laminate - Google Patents

Abstract

PURPOSE:To obtain the laminate excellent in mold releasing property for a panel plate even if outer mold release agent is not used by applying the forming pressure under heating repeatedly at the pressure equal to or lower than the maximum forming pressure, after phenol resin has been impregnated into the base material of cellulose family fiber paper cloth and it has been dried. CONSTITUTION:A prepreg is obtained, impregnating phenol resin into the base material of cellulose family fiber paper cloth and drying it. The objective laminate may be formed, while lowering the forming pressure of said prepreg to the pressure P2 in the range of 70-0% of forming pressure P1 from the time t1 of resin fusion starting temperature T1, and then raising and lowering said forming pressure at the internal of t0 in the period until the time t2 of resin fusion finishing temperature T2. EFFECT:The laminate with smooth surface may be formed without the occurrence of fiber exposure, and the fiber adhering to a flat panel surface may be prevented, thereby elongating the life of the panel plate.

For applying shielding agent 04J-Eiji rko external orchid! The cooking of the dust weakens the ``M power of the temporary shield salary, so the use of the external pane Rushi Oki J is σ Kobato.
L71 - Kai no Soshin's next face, which was caught by the 0-type ILτ, which was seriously damaged, and Tsui's leaking glare team, was also visible, and the fiber's shield phenomenon power u9 was also visible on the surface of the spring board.

(Objective of the Invention) The present invention has not been taken into account in view of this point, and is intended to weaken the secret force τ of the 7ffi<7ffi<, and to manufacture a laminated mount with improved M-type characteristics with the board. This is something provided by Toronoe T.

(Serialization of the invention) Uninvented, cellulose thread fiber paper base material, phenol fat τ thin film, dried Gripreg τ, M desired g copper ratio tsubame. In a similar manufacturing method, however, the molding pressure τ during bath melting of the honey is 70% to 0 of the molding pressure of the honey.

That is, by the molding method of the present invention, r:Jyll(
During the time t3 when the melting start temperature is 11゛1 and the end temperature is 1゛g, the molding pressure τM is lowered from the desired molding pressure P1 to Pltlc, and the cellulose ultrafine Between the small 11/'1 part of the resin store and the lecture room, place the resin cloth of the Miyazaki cloth in each station, press 8 steering molds, press P, and mold in one row.
