Title: Hiroyasu Ihara: Innovations in Composite Materials and Robotics

Introduction

Hiroyasu Ihara is an inventor based in Tokyo, Japan, whose work includes innovations in fiber-reinforced resin composites and robotic components. His listed portfolio includes 2 patents.

Latest Patents

Ihara’s latest patents address the performance and manufacture of advanced composite structures.

“Fiber-reinforced resin composite material and method for producing same” describes a composite with a simple-shape portion made from resin-impregnated reinforcing-fiber prepreg and an integrated complicated-shape portion. The resin used in the prepreg contains the same components as the resin in the complicated-shape portion. The invention aims to help prevent strength loss at the interface between the two portions.

“Robot hand” describes a robot hand made with laminated carbon-fiber-reinforced plastic (CFRP) layers and an intervening vibration-damping elastic layer. Alternating regions of viscoelastic resin and higher-rigidity resin are arranged across the CFRP layers. The viscoelastic regions help damp vibration, while the higher-rigidity regions improve flexural rigidity along the layers’ longitudinal direction.
