Title:
PELLET AND MOLDINGS
Document Type and Number:
Japanese Patent JP2023174702
Kind Code:
A
Abstract:
To realize composite resin moldings with high elastic modulus and high impact resistance.SOLUTION: A pellet contains a main resin 1 and a fibrous filler 2. An end portion in a fiber length direction of the fibrous filler 2 is defibrillated, and the defibrillated portion 3 is more than 5% and less than 50% of the fiber length of the entire fibrous filler 2. A fiber diameter at the defibrillated portion 3 is more than 1/1000 and less than 1/10 of the fiber diameter at the un-defibrillated portion. An aspect ratio of the un-defibrillated portion of the fibrous filler 2 is more than 5 and less than 1000. A modulus of elasticity of the fibrous filler 2 is greater than that of the main resin 1, and a difference between the modulus of elasticity of the fibrous filler 2 and that of the main resin 1 is within 20 GPa. Vacancies exist at an interface between the main resin 1 and the fibrous filler 2, and a volume of these vacancies is 10% or less of a volume of the fibrous filler.SELECTED DRAWING: Figure 1
