Abstract
A fiber-reinforced lightweight resin molded article with pores has a portion having a porosity lower than that of other general portions. Such a low-porosity portion serves as a rib in the resultant molded articles, to thereby enables to provide a fiber-reinforced lightweight resin molded article having excellent rigidity, bending strength, impact strength, uniformity of strength, resistance to local stress and torsion. The present invention also provides an efficient method for manufacturing the fiber-reinforced lightweight resin molded article.
