PURPOSE:To obtain a sheet excellent in heat resistance by using a glass fiber and a specific thermoplastic resin and specifying the heat absorption characteristics of the sheet. CONSTITUTION:The resin sheet is obtd. by using a glass fiber and a thermoplastic resin which has at least one group (A) selected from a 1-4C satd. aliph. hydrocarbon group and a 6-44C monocyclic, condensed polycyclic, or noncondensed polycyclic arom. hydrocarbon group (substd. by at least one 1-4C satd. aliph. hydrocarbon group) and at least one linkage (B) selected from ether, ketone, ester, amide, and imide linkages in a molar ratio of A to B of (1:9)-(9:1) and a mol.wt. of 10,000-300,000 (e.g. a polyarylene ether ketone). The sheet is made to have two endothermic peaks in a temp. range higher than the m. p. of the resin in the DSC curve obtd. by differential scanning calorimetry. |
