Glass fiber-silsesquioxane composite molded article and method for producing same

A glass cloth-silsesquioxane composite molded article, comprising:

• a glass cloth;
• and
• a cured product of silsesquioxane polymer that forms a composite with the glass cloth,
• wherein the silsesquioxane has a cage structure or partial cage structure,
• wherein the glass cloth-silsesquioxane composite molded article is obtained by impregnating the glass cloth with a composition containing at least one silsesquioxane having a polymerizable functional group represented by formula (A-3), and a curing agent, or a polymerization initiator,
• and subjecting the resultant to a curing reaction:
• wherein in the formula (A-3),
• R independently represents hydrogen;
• an alkyl having 1 to 45 carbon atoms in which any hydrogen may be substituted by fluorine and nonadjacent —CH2— may be substituted by —O— or a cycloalkylene;
• a cycloalkyl having 4 to 8 carbon atoms;
• or an aryl in which any hydrogen may be substituted by an alkyl having 1 to 10 carbon atoms, halogen, or fluorine;
• R1 independently represents a group selected from an alkyl having 1 to 4 carbon atoms, cyclopentyl, cyclohexyl, and phenyl;
• and at least one of X represents an alkyl having 1 to 10 carbon atoms having a polymerizable functional group, a cycloalkyl having a polymerizable functional group, or a phenyl having a polymerizable functional group, and the remainder of X represents a group defined in the same manner as R1,
• wherein the polymerizable functional group of X is selected from group represented by the formulas (d) and (e)
• wherein, R2 represents an alkylene having 1 to 10 carbon atoms, one —CH2— in the alkylene may be substituted by —O— or 1,4-phenylene;
• and R3 represents hydrogen or an alkyl having 1 to 6 carbon atoms.
