摘要： A prepreg for fiber-reinforced composite materials comprising (A) a reinforcing fiber having a modulus of elasticity of 200 GPa or more, (B) a fibrous thermoplastic resin having a modulus of elasticity of 100 GPa or less, and (C) a thermosetting matrix resin. The prepreg of the present invention does not only have excellent handling property equivalent to that of the prepreg with the conventional thermosetting resin as a matrix, but also gives excellent toughness to the resulting molded product without injuring the thermal and mechanical properties. Particularly, it has a high resistance to interlaminar fracture when exposed to impact, so that it is preferably used as a structural material for airplanes, etc.
摘要翻译： 1.一种纤维增强复合材料用预浸料，其特征在于：（A）弹性模量为200GPa以上的增强纤维，（B）弹性模量为100GPa以下的纤维状热塑性树脂，（C）基质树脂。本发明的预浸料不仅具有与以往的热固性树脂为基质的预浸料相当的优异的处理性，而且对所得的成型体产生优异的韧性，而不损害热和机械性能。特别地，当暴露于冲击时，其具有高的层间断裂性，因此优选用作飞机等的结构材料。

摘要： Oxidizing treatment of carbon fibers under specific conditions provides carbon fibers having oxygen concentration (O.sub.1S /C.sub.1S atom number ratio) in the surface part of the carbon fibers of 0.05 to 0.30 as measured by X-ray photoelectron spectroscopy, coefficients of water-extractable fraction of up to 2.0, and coefficients of tow spread of at least 1.times.10.sup.-3. These carbon fibers are excellent in adhesion to various matrix resins and when mixed as reinforcements with matrix resins, provide composite materials superior especially in impact resistance. The thus obtained composite materials are useful for aircraft, automobiles, and general industrial materials.

摘要： A non-solvent type thermosetting resin film exhibiting excellent uniformity in thickness is prepared by a process wherein a molten thermosetting resin composition having a curing agent incorporated therein is extruded through a linear slit of a flat die, maintained at a constant temperature, onto a release sheet continuously moving at a constant rate in close proximity to the exit end of the linear slit. As the flat die a flat sheeting die having a substantially circular manifold is used and the molten thermosetting resin is extruded onto the release sheet, which is supported by a back-up roll and confronts the exit end of the linear slit of the flat sheeting die.
