The procedure of example 1 was followed except that in step (1), MEKP-9 was replaced with a dimethyl phthalate solution of cyclohexanone peroxide (cyclohexanone peroxide concentration of 50% by mass).
Example 9
The procedure of example 1 was followed except that in step (1), the mass ratio of methyl methacrylate to styrene was 1: 1.
Comparative example 1
The procedure of example 1 was followed except that in step (1), the mass ratio of methyl methacrylate to styrene was 6: 1.
Comparative example 2
The method of example 1 was followed except that, in the step (2), the mass ratio of the resin composition to the alkali-free glass fiber cloth was 50: 50.
comparative example 3
The method of example 1 was followed except that, in the step (2), the mass ratio of the resin composition to the alkali-free glass fiber cloth was 90: 10.
comparative example 4
The process of example 1 was followed except that in step (1), the ratio of the total mass of methyl methacrylate and styrene to the mass of MEKP-9 was 100: 4.
In this comparative example, since the reaction was too rapid, local implosion occurred during the resin curing molding process, the wettability of the resin and the glass fiber was decreased in a microscopic state, and the prepared PMMA/glass fiber composite exhibited an overall whitish appearance (opaque).
